Top Benefits Of Automated PCB Manufacturing And Assembly

In most cases, the development of electronic devices is not possible without PCBs. As machinery and automation have improved, it has become simpler to create and build PCBs. When it came to assembling circuitry, the old method of manual assembly meant slow manufacturing. Besides this, the method provides less reliability. There are many sectors that could benefit from automating their PCB production processes. Some of the advantages of the assembly of PCB are below.

Components Of An Automated Printed Circuit Board Production Line

1.    Drill Through and Via Holes

Drilling for interconnects and through-hole elements is often the first stage in the circuit board manufacturing process. The step occurs after deburring and cleaning processes. A drilling machine is useful for this process. Because it can create holes as tiny as a hundred microns, or ten thousand times thinner than human hairs (which are approximately hundred and fifty microns in diameter). In order to switch between different dimension bits, this system does so mechanically.

2.    Photographic Mapping and Resistant Layering

Printed circuit board traces and copper fill sections form by printing a negative picture of the final copper onto a glass sheet. This is possible using the provided Gerber data. Both sides of the panel have a photoresist. The photoresist is a material that changes color in the light. The printed layer aligns with the bottom and top of the panel. It allows UV lights to be hard the photosensitive in empty spaces. To expose the copper beneath the uncured photoresist, subsequent processing involves washing away the former.

The electronic board is still a piece of a larger panel that may feature multiple layouts. Many stages of cleaning and inspection, including optical procedures, spread out during the course of printed circuit board production. It makes sure to catch and correct problems at the earliest feasible stages.

3.    Surface Treatments and Chemical Operations


The original foil strengthens and forms a conducting path. Conducting path is formed through hole connections and vias electroformed on PCBs. Copper-plated thicknesses are customizable per customer request. The entire process for consistent quality.

4.    HASL, Silk Screen, and Solder Mask for electronics manufacturing

To shield the copper lines on a printed circuit board, a liquid solder mask gets applied on both sides of the board. A translucent printed layer is then put on both sides of the boards before they get heated to a full state. Following the removal of the uncovered solder mask, a UV procedure becomes applicable. It hardens the uncovered solder mask, mimicking the prior photoresist procedure.

The silkscreen is a visible layer applied by a printing technique. It finds use for component labeling and identification. Finally, a method like HASL is used to prevent oxidation of the uncovered solder pads. The PCB’s ability to resist and conduct current flow must be verified. This is possible using flying leads probing inspection to verify proper functionality.

5.    Systematic Methods for Routing and Profile Creation

When all the PCBs on a screen get processed and validated. The internal characteristics of the boards get routed using a computer-controlled router. For example, the board’s profile and any features that aren’t via holes. It is not necessary for these to have a perfect right angle. Before this procedure, boards can alternatively be v-scored (sliced in a “v”). Although after delivery, consumers can disassemble modules.

6.    Wrap Up, Box Up, and Send

PCBs are ready to pack and dispatch to clients. After they have undergone final cleaning, testing to remove inspection and routing artifacts. The journey to this point is nothing short of miraculous.

Benefits of Automated PCB Assembly process and Manufacturing 

1.     Reduced Price

Saving money is a side benefit of using automated PCB fabrication. When it comes to assembling the electronic circuit before manufacturing. Many Surface Mount Technology manufacturers rely on proprietary technology. Carry out this to lessen the likelihood of glitches and lags. Developers of printed circuit boards (PCBs) can fix any design defects at this stage. This prevents problems in the final product. Mistakes like missing polarity markers and the wrong footprints can delay a project. Fewer workers require to complete the production because of the automated machinery. The cost of making PCBs for the manufacturer can go down as a result of these reductions.

2.     Human error is less likely to occur.

In order to assemble circuitry, one must pay close attention to every detail. This is becoming even more true as products become smaller and their parts decrease in size. This, in fact, can lead to higher mistake rates whenever human involvement is required. Inaccuracy is less likely now because the procedure is automatic. Automation not only speeds up fabrication but also saves money. It also decreases the potential for mistakes.

Assembly of printed circuit boards (PCBs) can be a finicky and challenging procedure. Assembly of circuit boards requires extreme precision. Components and circuit boards are getting smaller. It means more care is essential while soldering them together to avoid mistakes. Both humans and machines make mistakes. But, machines are significantly less prone to make mistakes when doing routine or delicate activities. In these conditions, automatic systems are more efficient and reliable than human workers. In conclusion, machines used in precise settings can help lessen the possibility of inaccuracy.

3.     Quick Product Production

The greater amount of time needed for hand assembly has a major effect on product creation times. Automation, on the other hand, allows for faster software development. This is because of the fact that you can finish other operations in parallel. Also, you are certain of the board’s delivery dates.

Because an automatic machine is there to perform a given operation consistently, electronic circuit precision and reliability can be consistently greater than human assembly. Since automation makes it possible to maintain the similarity of each board manufactured, you may anticipate superior products when working with an assembling service.

4.     Consistency

Due to the inherent error margins in hand-made circuit boards, consistency is problematic. But automation guarantees reliability and uniform quality every time.

5.     It’s ideal for mass production.

Automation facilitates mass manufacturing because it shortens production times and lowers production costs. And because reliability is already in, you know that even in bulk, quality standards will be met.

6.     Shortened Time to Market for New Products

There is no standard timeframe for a hand-assembled product because it depends on the circuit board. When there are other tasks in parallel, the time it takes to hand-make PCBs may not be worth it. By outsourcing to a PCB assembly firm that uses automated equipment, you can rest assured that your boards will arrive in perfect shape and get through multiple steps quickly and easily. Therefore, you will avoid wasting time and resources.

7.     Higher Degrees of Customization

Customization of products to meet individual needs is a side effect of the increased production flexibility made possible by automation. Electronic goods have typically been mass-produced to the same standard. Smart industries are expected to alter this.

The speed with which manufacturers of original equipment may create prototypes and, by extension, new products will also increase as a result of this increased adaptability.
