All You Need to Know about High Volume PCB

Circuit boards have become a key cog of every electronic equipment and device in the present-day world. Considering our ever-increasing reliance on electronics for diverse purposes starting from our homes to our workplaces, then the importance of circuit boards will only but increase with time. It is something that I find fascinating considering the evolution of circuit boards from the breadboard days to the new complex, miniaturized printed circuit boards.

Our overreliance on printed circuit boards for our electronic needs calls for a high volume PCB assembly and PCB mass production. Because of this, it not only becomes crucial to undertake high volume PCB production and get an ideal high volume PCB manufacturer to cater to these needs. This article canvasses all the key aspects you need to know about high-volume printed circuit boards. So let us dig in, shall we?

High Volume PCB Production and Assembly

The subject of high volume PCB production and assembly can often prove confusing for both experienced and fresh faces in the circuit board industry. For starters, therefore, it becomes essential to detail what high volume PCB production and assembly refers to and get it out of the way. So what is it all about?

• High Volume PCB Production

High volume PCB production refers to the last step of the circuit board production process before delivery to customers or clients. It always features no design changes with a linear process that results in large volumes of printed circuit boards. The aim of this process entails producing high volumes of PCBs as required by the client at the least costs, albeit with a high yield rate.

• High Volume PCB Assembly

High volume PCB assembly implies the assembly of printed circuit boards of ten thousand plus pieces with DFT and DFM. Such a high number requires you to understand what type of PCB you want before engaging a PCB company for your mass PCB needs. Otherwise, you can end up with large PCB of excellent quality that cannot help your electronic needs. Therefore, the significance of picking the right printed circuit board cannot get understated, especially when it comes to influencing the performance of your electronic product.

What better-printed circuit board manufacturing company to engage for your high volume PCB production and assembly needs than the RayMing PCB and Assembly Company? The company will not only guarantee your mass PCB supply needs through its manufacturing facility but wow you with its printed circuit board capacity in aspects like quick delivery, cost reduction, etc. Additionally, the company possesses high lever printed circuit board equipment to secure your orders, adhere to stringent quality control measures in delivering high-quality printed circuit boards. What’s more, the company has a round-the-clock customer support service to ensure a seamless experience during the high volume PCB production and assembly process.   

Maximizing the PCB Production and Assembly Process

In most instances, if not all, maximizing the high volume PCB production and assembly process efficiency often hinges on optimizing the low volume production process. So to maximize the high volume production and assembly process, it becomes imperative to maximize the printed circuit board prototyping phase. So how can you ensure this?

• Pick a qualified contract manufacturer for your printed circuit board design. The quality of low volume PCB production often hinges on the contract manufacturer’s expertise and equipment in meeting your design needs.
• Tailor your PCB design to your contract manufacturer’s capabilities. It becomes essential to use specifications that align with the contract manufacturer’s equipment capabilities to ensure timely deliveries, prevent the need for redesigning, and avoid extra development costs.
• Optimize the selection of your components. A shortage of components often proves a common reason for stalled or disrupted production. It, therefore, becomes pivotal to ensure that all crucial components (of acceptable quality) are available for your anticipated production levels.   
• Apply decent DFM (design for manufacturing) guidelines. It becomes crucial to assist the low-level production of your printed circuit boards by following design for manufacturing guidelines and rules specific to your contract manufacturer. It will, in turn, help with your high-volume PCB production and assembly process.
• Perform the required testing of the printed circuit boards. It becomes vital to ensure that every regulatory testing gets conducted on your printed circuit boards post the prototyping stage. However, you should always try and go beyond by performing extra tests to ensure aspects like structural integrity prove sound.

If you optimize the low volume production phase by sticking to the detailed aspects, you will optimize your printed circuit boards’ high volume production and assembly process. Here, it becomes essential to remember that the initial stages of the production process prove essential as it acts as the basis for the high volume PCB production and assembly.

Easing the Transition from Low Volume/Prototyping to High Volume Printed Circuit Board Production

You sure understand the importance of PCBs and how the prototyping stage and its optimization impact high volume PCB production. So what happens during the transition process, and how can you seamlessly transition from prototyping to high volume mass production.  

Like in most other real-life situations, the transition from low volume to mass production can prove difficult, though it always comes with incredible gain. In electronics, this prototype-to-mass production transition often proves a significant one. While the base unit remains constant from the prototype level to the high volume production of printed circuit boards, the specific processes often prove unique with particular objectives.

Becoming aware of the differences between the objectives becomes pivotal for engineers and designers of PCBs when picking the ideal contract manufacturer for the two product development phases. Additionally, such knowledge also becomes invaluable in easing the transition from the low volume/prototype phase into the mass or high volume production phase.

Before we delve into the transition process, it becomes necessary to understand what PCB prototyping and high volume production imply. Firstly, the prototyping of PCBs infers the development of small quantities of printed circuit boards that can get deployed for design validation processes by testing the system’s performance and operation. Therefore, the process must feature aspects such as flexibility, prove sufficiently fast, and get carried out by quality contract manufacturers besides consistent testing. At this stage, any design issues get corrected to avoid any issues on the development of the printed circuit board or post-production in its lifecycle when deployed.    

Conversely, high volume PCB production aims at reliably and efficiently producing high-quality printed circuit boards. The assumption at this stage always encompasses aspects such as the components, design, operation, and functionality having gotten sorted out in the prototyping phase. Because of this, the focus during high volume PCB production revolves around attributes such as reliability, testing, and cost-effectiveness.   

Reliability becomes key because of the large number of printed circuit boards involved that must prove similar in design and quality and at a high yield rate. On the other hand, testing becomes crucial because of ensuring high-quality standards of the PCBs post-production. Finally, the cost aspect becomes crucial because of the large quantity of printed circuit board units. The large number ensures lower costs of production utilizing the principle of economies of scale.

It, therefore, becomes apparent that the objectives between prototyping of PCBs and mass production/high volume production are different.  Consequently, transitioning from one phase to the other will require numerous changes, which include contract manufacturers (when the CM specializes in either of the two). However, it is important to state that if you contact us at RayMing PCB and Assembly, you will not need to change and contract another firm as we cover both aspects.   

The Transition from Prototyping to High Volume Production of Printed Circuit Boards

The transition from the PCB prototyping phase into mass/high volume production must prove seamless and direct in ideal circumstances. However, the transition is never as seamless as everyone would want. Here, you can face countless challenges, such as the need for readjustment of the design files to facilitate quality printed circuit boards. However, the absence of such files can become costly as you will spend more time and money to rectify and produce quality PCBs by having to make engineering design changes.  

Other crucial issues that may arise in the absence of design files include the need to obtain and submit extra design files from your prototype manufacturer to the contract manufacturer. Additionally, your contract manufacturer may lack the capacity to develop your circuit boards in line with similar specifications detailed by your prototype contract manufacturer. It also becomes typical to find components missing even during the PCB production phase. Finally, design changes may become necessary, especially when under performance and operational inadequacies need re-prototyping and redesigning.

Such issues, when they crop up, can delay the high volume PCB production process because of the countless redesign needs you will have to do before the mass production.  While it may not always seem possible to resolve or avert all the potential issues that might crop up, it becomes possible to ease the transition by adopting some crucial PCB product development process guidelines. So how can you ease the transition process from the prototyping phase into the high volume production process?

The best way of ensuring a smooth transition from prototyping into high volume production of printed circuit boards entail finding and picking a contract manufacturer willing to collaborate in creating an excellent final prototype design besides as-built design files to eradicate the need for engineering change order and therefore speed up the high volume production process.

Benefits of Mass/High Volume PCB Assembly

The benefits that accrue from a high volume printed circuit board are numerous and significant.  The benefits include the following.

• High volume printed circuit board assembly encompasses the need for the prototyping and design functions to get carried out in one go, ensuring that the prototype gets meticulously developed and tested to guarantee accurate functioning. Therefore, it becomes simple to get the large production run going.
• The high volume PCB assembly ensures mass production of printed circuit board products, something that becomes incredibly useful in going to market at a mass or large-scale level. It ensures large numbers of quality printed circuit board products and quick turnaround periods. Such a situation proves ideal for getting to the market quickly and ahead of the existing competition.
• Another incredible benefit of high volume printed circuit board production entails the aspect of low production cost. Many cost-related benefits accrue from engaging in a high volume printed circuit board production as high volumes often result in economies of scale. The production cost will impact the pricing of your printed circuit board which enhances your competitive edge in the electronics market. It acts differently from an instance where you produce and assemble small batches, as this always tends to increase the cost.  
• High-volume printed circuit board production and assembly also provide a shortened production cycle, all thanks to automation. Therefore, it plays a major role in your production pipeline and the go-to-market strategy, which gets a major boost.
• The mass or high volume production of printed circuit boards also ensures the production consistency and uniformity in features. It results from a scenario that the assembly of each printed circuit board gets a similar assembly and testing regime, which in turn guarantees the quality.

Application Areas of High Volume Printed Circuit Board Assembly Services

• High-volume printed circuit board assembly services apply in the mass production of electronic appliances.
• Under typical circumstances, the entry process into new or existing markets in diverse geographical areas requires large-scale printed circuit boards. Because of this, high volume PCB assembly services apply significantly.
• Mass volumes of PCBs also find application immediately printed circuit boards go beyond the prototype phase of the development, and once every error, if any, gets corrected. It especially becomes essential before the PCBs get to the market. Because of this, it features prominently in the electronic manufacturing sphere, especially for companies where consistency and uniformity prove key.

Designing a Military Printed Circuit Board

The conceptualization and design of the PCB often represent the first step in the entire production process of circuit boards, and as such, not any different from a military PCB. It includes diverse aspects that you must consider, including the type of military PCB. So what are these considerations?

• Board materials. It is an instrumental part of a military PCB design as you need to ascertain that every material is of a military-grade standard and specification.  Materials used for developing military PCBs need to prove heat resistant because of the application of the PCB in harsh weather conditions. Additionally, the deployment of thermal compounds becomes crucial in aiding heat dissipation.

Remember, a printed circuit board needs non-conductive and conductive materials to work. As much as the material considerations need adhering, it should happen in line with base material needs (ceramic or FR-4, comprising glass-reinforced epoxy) and the conductive copper layer. Since most military PCB are high-performance circuits, the base materials will comprise mainly ceramic or PTFE bases.

• PCB stack-up. In this case, the printed circuit board stack-up infers to the layer number that a military PCB will need. It is crucial to determine this in the design phase to help you understand the necessary impedance for each layer, besides the correct fabrication process to pursue. Such determinations help figure out the anticipated yield, minimize the cost of production, and ensure reliability.
• Copper traces. A printed circuit board circuit’s copper traces are important in transmitting electrical and other types of signals in the PCB. It is vital to comprehend the attributes of the copper traces besides its limitation during the design phase.
• Via types

The type of via becomes instrumental in connecting the diverse military components in the military PCB. It includes through-hole, blind, micro, and buried vias. However, all top-quality PCBs have a reduced number of vias. Additionally, the current carrying capacity of the via becomes a crucial factor to consider when designing the PCB.

• Picking components. A military PCB contains not only one military component but a myriad of them. Consequently, you will have to factor this in your design requires diverse types of military component types. It becomes crucial to pick the correct components for your military PCB to reduce errors and ensure high standards of PCB quality.
• Design rules. It becomes essential to consider the design rules post the considerations already elucidated. Here, aspects such as component placement, DFM, layer allocation cross-talk budgets, and flight time should get considered. Other components that will work in close correlation with the PCB, such as a military grade capacitors, need to be factored in the military PCB design.
• Power and signal integrity

A quality military printed circuit board possesses sound power and signal integrity. For this aspect, key considerations should include the signal rise and signal fall times, characteristic impedance, rack lengths, and drive strength. However, the signal integrity simulation has to get underway before and after the layout for a quality performance guarantee. Additionally, the power distribution’s DC and AC performance needs to get considered as well.         

Prototyping a Military PCB

Military printed circuit boards, like other PCBs, need a prototyping phase. It should include the following process steps.

• Design. It represents an important step, and as discussed above, sets the tone for the prototyping and production process of the military PCB. Here, it becomes pivotal to deploy a relevant printed circuit board design software to make your prototype. Additionally, it is crucial to indicate the design software used when sending the military design file to your prototype contract manufacturer.  
• Schematic design. The stage encompasses describing useful information that the engineers will use to prototype your military printed circuit board. It is crucial to detail the materials, military components (PCB), component placement, and the circuit board’s function. Additionally, the panel and grid size needs to get picked at this stage.

While acting as a segment of the initial design phase, this stage also encompasses checks through simulations to ensure the accuracy and functionality of the military PCB design.  

• Bill of materials. It is crucial to develop a listing of all the components and materials required in the prototyping process. It is especially pivotal when trying to self-sourced for the military PCB materials. The bill of materials also becomes crucial for the contract military PCB prototype manufacturer, especially in sourcing your printed circuit board materials. It enhances your military PCB’s accuracy per the schematic. A BOM encompasses details like:
• Value. It specifies the specifications in units of the component. It includes units like ohms, etc.
• Quantity. Encompasses the military PCB components needed
• Reference designators. It covers codes deployed in the identification of certain parts
• Footprint. It is a precise location of particular components on the printed circuit board prototype.
• Manufacturer parts number. The number indicates the part’s number according to the component manufacturer.

Upon finalizing the design schematic and BOM, a check to ascertain that you have all the applicable parts becomes necessary. To enlist the assistance of an expert like a component engineer in ascertaining the parts selection vis-à-vis their suitability to the budget, military PCB prototype design, and size requirements.

• Routing design. It is the next step and entails the design of the military PCB prototype routing. It gets accomplished by deploying traces to link or connect diverse PCB components. Additionally, it becomes useful to remember the diverse factors that impact the routing approach. It entails signal noise generation, noise sensitivity, and power levels.

However, you have to note that most PCB designs use the netlist information to plan the military printed circuit board routing. Using a software program, it becomes simple to automatically compute the optimal routes of the printed circuit board using aspects like layer number, etc. However, it can take a long time, especially when the military PCB proves larger than the standard ones besides having a lot of components.

• Checks. The fabrication phase can always feature plenty of functionality issues. However, checking the PCB prototype design constantly while undergoing the prototyping phase reduces these issues. Some of the standard printed circuit board problems you must factor in include thermal issues such as heat spots. It is also crucial to maintain the military printed circuit board at consistent temperatures. Therefore, the need to address all arising issues from the design attributes such as thermal paths, copper thickness, the large printed circuit board size, layer number, and inconsistent temperatures.  
• DRC (Design Rule Check). Besides the DRC, you should also do the LVS (layout-versus-schematic), an antenna check, and ERC (electrical rule check). Additionally, other manufacturers conduct other QAA (quality assurance assessments). Upon the conclusion of this step, you can submit the military printed circuit board prototype design for fabrication.

While this process step ends the design and testing phase, the next phase entails the fabrication stage.

• Photo film development.  Here, RayMing PCB company experts like our engineers will deploy your military prototype design in developing a photo film consistent with your design needs using a printer or plotter. The printer ensures the printing of the military PCB layers and solder mask. Remember, the film often refers to printed photo negative plastic sheet of the board. It marks the conductive copper sections and the non-conductive sections of the military PCB prototype.  
• Printing the inner layers

It features a stage where a copper layer gets applied to the military grade PCB substrate material. The process commences with the pre-bonding process of the copper on the substrate before applying the photoresist. The photoresist often comes as a photosensitive film, which hardens when exposed to UV light. Additionally, blocked sections (often with black ink) stay soft. The last sub-step entails the removal of the soft photoresist while leaving the hardened sections to shield the copper. It is then followed closely with removing the hardened part or UV-exposed photoresist to expose the copper layers in the designated spots of your military PCB design.

• Aligning the military PCB prototype’s layers

Most military PCBs have multiple layers, and this can exceed ten layers to twenty-eight layers. In such instances, it is prudent to align these layers accurately before proceeding with the precise punching of registration holes. It is significant to ensure accuracy in the alignment process to prevent revision of the process, especially in the inner layers, which proves a tough ask post the fusion of the layers.

• Fusing the Military PCB layers

It encompasses the fusion of Prepreg and the original substrate, often clad with copper foil traces. The process step entails two steps. Firstly, the layering up phase, before the bonding phase ensues.

Fusion of the layers begins by putting the Prepreg layer atop the alignment basin. The substrate layers then get stacked before incorporating the copper sheet and another Prepreg layer. Atop the Prepreg sheet, the incorporation of another aluminum layer gets underway before topping it all off with the copper press plate. After the incorporation of the layers, everything gets fitted into the pin-attached steel table.

After this, a computer-controlled bonding press ensues. It heats the PCB stack, applies pressure before cooling it down afresh. After that, the pins get removed to uncouple the pressure plate before unpacking and obtaining your military PCB prototype.

• Drilling holes. It is prudent to note that the process continues, and at this point, you have to drill holes into the stack. It is instrumental whenever you begin adding the components. However, precision becomes key, and computer-controlled equipment eliminates the hustle you would otherwise have to go through.   
• Copper plating. It encompasses the incorporation of a copper layer on the military PCB surface through a chemical bath phase. The copper acts to shield the entire panel, including the hole’s interiors. It is also controlled by programmed machines to increase and ascertain precision.  
• Outer layer imaging. It follows the copper plating process closely. It entails applying another layer of photoresist on the printed circuit board panel, which allows for the outer layer imaging of the military PCB prototype. Remember, the process proves similar to the already discussed process of creating the inner layer’s inversion.  
• Tin and copper plating

It follows the outer layer imaging process step and entails the addition of another copper layer. However, unlike in earlier instances, the photoresist will ensure the copper deposition exclusively on the anticipated PCB board sections. After that, the military PCB board receives a round of tin plating to protect the copper layer in subsequent steps.

• Final etching. It encompasses the removal of any excess copper by utilizing a chemical process reaction. However, the tin plating protects the fundamental copper traces within the conductive sections. Hooray! You will have successfully established your PCB’s conductive connections.
• Applying the solder mask

The process entails the panel or board cleaning before subjecting it to the solder mask application. It then passes through a hardening phase through exposure to UV radiation to toughen up the solder’s photo film. Elimination of undesired soft parts gets carried out at this point.  

• Surface finish application

It encompasses the deposition of extra gold or silver plating. What’s more, the process also involves the hot-air leveling of the pads to ensure uniformity.

• Applying silkscreen

The military PCB surface gets a silkscreen through ink-jet writing, ensuring the proper conveyance of vital information concerning the printed circuit board.  

• Cutting. PCBs often get extracted from a larger panel at this point. To ensure this, it has to get cut from this panel using a router or v-groove cut. However, before you extract the PCB from the larger panel, please ensure that it passes the electrical test, and its functionality is as stipulated in the design. After this, pop the segment cut to obtain your PCB board.  
• Sourcing. Preparing for the assembly process requires sourcing crucial military PCB components, something you can achieve either by relying on the PCB prototype solutions company or by yourself. The bill of materials becomes crucial as it guides the solutions provider with the sourcing of the military PCB components. What’s more? The BOM will ensure that the components sourced are of satisfactory quality according to your military PCB design.   
• Assembly. It closely follows the component sourcing stage immediately after it finalizes. It encompasses attaching the necessary components to your military circuit board.  
• Stenciling of the solder paste. The process step entails the solder paste application onto the circuit board. It combines the solder with the flux and proves helpful in melting the solder and bonding it with the circuit board. In this case of stainless steel, the stencil gets placed on the PCB to permit the solder paste application, especially in precise areas where components will get stationed. The stencil ensures the even spread of the solder paste, after which it gets removed to expose the even and correctly applied solder paste.  
• Pick and place. It ensures the perfect placing components on the prototype board’s surface through a mechanism of picking and placing, often aided by a computerized machine. It also ensures the placement of the non-connector parts on top of the solder paste in the designated spots.
• Reflow soldering. It proves pivotal in attaching the surface-mount components to the military PCB. The process gets carried by placing the circuit board on a conveyor belt before passing it through an oven (reflow). Reflow ovens have heaters that steadily and slowly heat the circuit board to about 480 degrees Fahrenheit. It is essential as the heat ends up melting the solder before cooling and solidifying the solder, which ensures the permanent placement of the SMDs to the military PCB.  It is vital to use a stencil before carrying out the reflow process independently for double-sided printed circuit boards.
• Quality control and inspection

Accidental movements at times happen during the process of oven reflow, which has the untidy outcome of poor connectivity, electrical shorts, or a lack of connection. Therefore, it is prudent to ascertain that the circuit board possesses no errors after completing the reflow phase. It gets carried out through manual checks, automatic optical inspection, and x-ray inspection. Additionally, checking by testing the functionality and quality of the PCB is crucial.

• Slotting in through-hole components

Some military prototype boards require more components aside from the SMDs. It entails the plated through-hole parts, which get plated all over to improve transmission and receptivity of electrical signals, either side of the board. However, please note that solder paste will not work on PTH parts as it runs through the PTH without adhering. It, therefore, requires manual soldering or wave soldering, where the circuit board atop a conveyor passes through the oven to apply molten solder on the board’s base. The process ensures the simultaneous soldering of the PCB pins. However, it lacks effectiveness when it comes to double-sided boards.  

• Functionality tests

The last stage of the prototyping process entails a myriad of tests to ascertain the functionality of the military PCB. Here, the board gets tested under the respective simulated setting mimicking the anticipated operating environment of the military PCB, once mass-produced and deployed for use.

Military PCB Manufacturer

Mass manufacturing and assembly of military PCBs come after the prototyping stage. However, it becomes essential to pick an ideal manufacturer for your military PCB needs. Some of the standard considerations you should take into account before picking a military PCB manufacturer include the following.

• The military PCB manufacturer needs to have a solid industry reputation. It includes having a demonstrated history and experience of sourcing for military-grade components and materials and producing quality military PCBs. Additionally, the manufacturer must demonstrate a history and reputation of delivering on time and honoring its contractual obligation.
• The military PCB manufacturer also needs to have a simple and easily accessible system for making military PCB orders and submitting Gerber files.
• The manufacturer will also have to possess top-of-the-range manufacturing equipment and the latest technologies besides skilled personnel to handle your military PCB needs.
