There are many names for prototype printed circuit board (PCB) assembly. Other names you will commonly hear are: surface-mount technology (SMT) PCB prototypes, PCBA prototype assembly, PCB sample assembly, etc. The term PCB assembly
refers to a fast prototype PCBA used to test the function of new electronic designs. These help with quality assurance, verifying that there is no problem with the test product, finding bugs, and updating the design. Typically, before mass production, one electronic project will need 2-3 iterations of a SMT assembly to make sure everything is working perfecty.
RayMing supports engineers to assemble their electronic prototype quickly and cost effectively during the whole design verification process. To ensure that the product design meets requirements, in general, we suggest 5 pcb or 10pcs for prototype assembly testing. Of course, one or two piece is also OK, so long as it can be verified.

How to guarantee high quality PCBA assembly ?
How to choose prototype pcb manufacturing
PCBA sample assembly is a complex and highly professional process. In recent years, SMT assembly manufacturers have developed rapidly. Many electronic engineers or electronic device manufacturers do not know where to start due to lack of professional knowledge and experience when selecting specific PCBA manufacturers.
First, when choosing a prototype assembly manufacturer, the first thing to check is whether the manufacturer is professional by checking for two aspects: equipment and management system. Generally speaking, the more professional PCB assembly manufacturers have more advanced and complete equipment, which is the basis for completing SMT assembly. Moreover, a good SMT manufacturer will also pass the ISO 9001 quality management system test, and will also be registered with the relevant national quality inspection departments. These qualifications and certificates can help you initially determine whether the manufacturer is professional.
Second, the “feel” of your service. An SMT assembly factory provides your PCBA assembly services, not the final product. Therefore, the service attitude of an SMT manufacturer is very important. A more formal manufacturer encounters problems or problems with customers. When other new requirements and suggestions are made, we will actively listen to customers’ opinions and make changes and improvements in time to satisfy customers. By inspecting a manufacturer’s service culture, you can make judgments about the quality of the employees engaged in SMT assembly and the overall corporate culture.
Third, look at the reputation. Industry reputation is a good reference factor for us to choose pcb prototype and assembly manufacturers. Manufacturers with good reputations generally have greater advantages in the industry in terms of quotes, service, industry experience, and R&D. It is recommended that we prioritize manufacturers with good market reputations, which will save us a lot of energy and time in the later stages.
This has been an introduction into the more important items related to the selection of SMT patch proofing manufacturers. SMT patch proofing is a must for everyone. Therefore, when choosing a service manufacturer, you should not be negligent. It is recommended that you build on the introductory content above. Comprehensive considerations ensures that you choose the most suitable prototype smt assembly manufacturer.
Anyone interested in electronics and electronic circuit boards needs to understand the various stages of developing and producing a printed circuit board. It can come in handy when you are seeking a top prototype smt assembly provider. The various production stages of printed circuit boards entail design, prototyping (prototype PCB development and rapid prototyping pcb assembly), and PCB high volume production. Different entities will always seek part of the whole production process depending on their electronic circuit board needs.
However, this article seeks to help you understand everything about prototype PCB assembly, a fundamental aspect of the PCB production process.
Rapid prototyping pcb assembly represents a fundamental phase of the printed circuit production process. It is also inferred as PCBA prototype assembly, SMT or surface-mount technology PCB prototype, PCB sample assembly, etc. From these alternative names, the meaning of prototype assembly regarding printed circuit boards becomes apparent. So what is assembly prototype?
PCB prototype assembly service is a fast prototype printed circuit board assembly primarily used to test fresh or new electronic designs. Consequently, it assists with checking and ensuring quality assurance of the PCB. For instance, it verifies that no bug exists in the test PCB, updates the design, and finds bugs. In most instances, prototype assembly of an electronic project will require two or three iterations to ensure everything is perfect.
If you have developed a printed circuit board design and want top prototype pcb assembly supplier, it becomes prudent to pick a top prototype circuit board assembly company. What better company than RayMing PCB and Assembly Company. The company assists engineers and designers in assembling their electronic prototypes at a cost-effective price and quickly. You will get quality prototype pcb assembly supplier because design verification also takes place. However, you have to provide the recommended five to ten pieces for the prototype assembly testing.
Printed Circuit Board Services to Consider when Picking a Top Prototype PCBA Company
- Engineering services on offer, and which relate to the prototype printed circuit board
- Here it would help if you considered whether the company offers DFM or design for manufacturing services. Additionally, it should also provide DFT (design for testing) and DOF (design of experiments). DOE entails value-added engineering services developed control plans.
- Prototype assembly services that the company offers. It would be best to determine whether the PCB assembly company performs single and double-sided surface-mount assembly. It should also have the capacity to perform selective soldering and plated through-hole. Additionally, mixed technologies also help, therefore, consider one that can combine through-hole, electro-mechanical, and SMT assembly.
- Printed circuit board assembly function testing
- Here, it becomes prudent to consider services such as flying probe testing, circuit wire bonding, and in-circuit testing. Additionally, the company should also provide PCBA conformal coat and functional testing.
Prototype Printed Circuit Board Assembly Process Steps
Understanding the PCB prototype assembly process becomes key in estimating the cost and other related aspects before approaching a prototype pcb production company. The assembly process includes the following.
- It represents the first step, and it starts by allocating a distinct 2D barcode for each printed circuit board. The barcode becomes instrumental in allowing any needed trace-back, and for this to get achieved, the barcode gets scanned throughout the assembly process. Crucial information like supplier details and every component’s delivery documents also get tracked. Further, the process steps deployed, the time, and the person who undertook the process also need to get linked to the PCB specifications and BOM revisions.
- Stenciling of the solder paste. It is the second step of the assembly process and features equipment like a MEDL stencil printer incorporating solder paste on the bare printed circuit board.
- Pick and place. The third step entails placing the SMD components accurately using the pick and place machine.
- It comes after the accurate placement of the components. The inspection ensures that the correct orientation and placement of SMT (surface mount technology) components before relaying the assembly to the soldering stage.
- Reflow soldering. It is the next step in the assembly process, and the printed circuit board gets placed in the reflow oven with every relevant component. The oven often consists of diverse zones, and it ensures the hardening of the solder paste. However, it becomes essential to remember that using a solder paste with a low melting point stands recommended. It entails eliminating the risk of damaging any of the PCB components by the high temperatures accompanying the soldering process.
- Another round of inspection. It becomes essential to conduct another inspection round post the soldering process of the SMT components. It allows for the detection of any potential defects of solder joints. The inspection often gets completed manually or by a machine, depending on the requirements and specifications of the customer.
- Insertion of through-hole components. It is the next step after the second round of inspection. Through-hole components get placed manually on the printed circuit board, and thus, you must ensure the correct orientation. The soldering, however, gets carried out by a machine or manually- by hand, though this depends on the extent of the needed selective soldering.
- Technical edge cutting. It represents the subsequent stage post the insertion of the THT components. Before you start, however, you need to ascertain whether you will deploy automated machines for the assembly process or do it manually. If, for instance, you are using machines, then the printed circuit boards will get equipped with the technical edges, edges that need cutting off after completion of the assembly process. However, when the PCB comes as a panel and possesses numerous single circuits, it becomes imperative to separate the panel at this stage. Clean cutting of the edges requires you to ensure pre-cut V-cuts or break-out tabs early during the ordering process.
- At this stage, when the cutting off of the technical edges has already concluded, the third round of inspection happens. It is an inspection round that intends to verify the orientation and placement of every component to ensure it is all correct. Additionally, the inspection also ensures that the quality of the solder connections besides the edges proves top-notch.
- It comes as the next step after the last inspection. Here, the prototype PCB assemblies get packed in safe ESD packages. It is crucial to note that each assembly needs its ESD shielding bag. However, when the printed circuit board prototype dimensions surpass the standard packages, then the assemblies get packed in anti-static foam.
- Quality control. The last step before the packages gets closed for shipping entails a round of quality control check. Here a sample gets optically checked to ensure the PCBA prototype is of sound quality.
Estimating the Cost of a Prototype Assembly Project
The ability to accurately predict the cost of your prototype pcb production project can prove a tough ask. However, you can always come up with estimates of the total costs.
