All About Printed Circuit Board Fabrication

By Adele Madden


The latest innovations in the electronics industry brought about several advancements. This includes the increasing popularity of printed circuit board fabrication. Nowadays, more and more electronics builders are using this highly effective method because of the numerous advantages it brings. Accordingly, the PCB varies depending on its function. Not one board can set a definitive configuration because the layout must be specific for its purpose.

At present, many layout designers are using computer-aided design systems to create a more precise PCB outline. To perfectly fit the specific requirements for a product, a wide variety of materials are normally used to fabricate the printed boards. Copper is on top of the list. To prevent oxidation and extend its usability, its surface is coated with thin layers of lead. Other commonly used materials include nickel and gold because of their superior conductivity.

Meanwhile, the manufacturing process of PCB is complex and precise. It is extremely important that the entire process be done in a controlled and clean environment. The components must be free of any sort of contamination. Even its packaging follows a standard process as it could affect the overall performance of the final product.

The parts and components of a breadboard are highly sensitive. Minor and major damages alike can subvert its functionality deeming it useless. To prevent such damages, the boards have to be secured in a specially designated protective bag all the time. Its storage and shipment must be controlled to maintain its quality, especially when transporting to far-off locations.

Aside from the immaculate and painstaking layout, the designer must also look after the quality of the printed circuit boards. Quality control is a very important aspect to ensure superior performance. This entails thorough ocular inspection from the start of the manufacturing to its electrical testing towards the post-production phase. There could be flaws that must be corrected in the process.

Even the littlest details must be checked by the designers. Misplaced parts must be corrected. Excess solder paste should be cleaned out as it can possibly lead to various performance issues. Another common mistake that needs close monitoring is overheating of solders. It helps to do random tests on the products.

Furthermore, safety considerations must be taken into account. Every designer must be familiar with the proper use and handling of the materials. From its delivery to its disposal, there is a standard process being followed. Some of the components used in soldering may contain harmful toxins such as lead.

Every manufacturer must observe prudence in dealing with its waste materials, too. Recycling obsolete boards is highly encouraged as a means to conserve the environment. Throwing them into landfills may just add up to the ongoing pollution that has been haunting the society. To reduce the risks that come with the hazardous materials, there are newer varieties underway that are much safer to use.

There is a positive future for printed circuit board fabrication in the electronics industry. Who knows what could still happen in the years to come. There are amazing strides expected to affect PCB production in the near future. To maintain your lead, you must keep yourself updated with the recent developments in this industry.
