Printed circuit boards – or PCBs for brevity – are widely used in the field of electronics. They are usually made of copper sheets laminated or mounted onto a non-conductive backing material. Three main variants of printed circuit boards exist in the market: single layer (only one side is laminated with copper), double layer (both the front and back sides have copper), and multi-layer (two or more laminates on both sides of the board, with additional materials embedded for more effective conduction of electricity).
Printed circuit boards are best used in electronic circuits that call for complicated wiring. In fact, you can use them as more affordable alternatives for a fully wired system. Unlike traditional wire wraps utilized for old versions of circuits, electronic components, such as resistors and capacitors, are simply soldered on the PCB. This eliminates the need for wires altogether. However, before fixing these components into the printed circuit board itself, the wiring pattern needs to be etched first and the corresponding holes drilled onto it.
A handful of methods are used to etch the wiring pattern on the PCB prior to drilling, but most of these are industrial-scale processes best suited to fulfill a large quantity. The simplest method of etching, typically used by hobbyists and small-scale producers, is immersion chemical etching. First, the wiring pattern is drawn on the PCB’s copper layer using a marker or any resisting material. The panel is then soaked into an etching solution, usually ferric chloride, to remove any unnecessary copper. The chemical etching process takes time, but it can sped up with the application of heat.
After the etching process, the finished printed circuit boards are drilled at certain points to accommodate electrical components to be soldered onto it. After attaching the components, testing them for functionality comes next. Testing also determines if there are existing wiring connections that you should remove and if there are two points that you need to join together.
If the finished PCBs pass, you can then put them into anti-static packaging bags for transport. Packaging them into anti-static bags is important, as they are sensitive to even the simplest static charge. Nowadays, PCBs are also being used in the computing industry – from peripherals such as computer mouses to the complicated motherboards inside laptops and desktops.
Many companies have stringent requirements when it comes to printed circuit boards, and usually outsource their production to companies such as PCBNet.
One great thing about us here at PCBNet is that all the printed circuit boards we provide to customers meet the IPC-A-600F (Class 2) standard.
Usually, there are three main standards for circuit boards in the market today:
Class 1 (for general electronic products), Class 2 (for dedicated service electronic products), and Class 3 (for products used in certain applications that require high reliability). Our customers will have an assurance that PCBNet follows the same high quality standards, regardless if the board is a prototype or an actual one for manufacturing.
We, at PCBNet, pride ourselves in our full turnkey assembly and manufacturing process, which happens under one roof. This, alongside our capabilities and experience in the field of printed circuit board production, enables us to produce bulk orders within a shorter period. In addition, our available portfolio of materials allow for the creation of substrates designed for specialized applications. In cases where companies already have the required components for a certain project but lack the assembly capability, PCBNet can gladly do the work for them.
With our thorough inventory process in place, we make sure that all the necessary parts arrive in our facility before we start production. It’s no wonder why companies that rely on us for their PCB fabrication and assembly needs cite a shorter production time and increased efficiency without forsaking quality as reasons why they trust us. Our company is committed to help you out when it comes to PCBs. We are more than willing to extend our helping hand.
