Properly functioning printed circuit boards are essential for both manufacturers of electronic devices and also the developers if the overall intent is for the electronic device to function at high capacity. From designing the schematics of the printed circuit boards to testing the products, there is no process of PCB manufacturing and/or assembly that can be taken for granted. While it's true that you can attempt this process on your own, especially if you are in possession of a large scale manufacturing facility, here are a few reasons why it would be a better option to opt for a professional company for PCB manufacturing and assembly. 1. Variety A professional printed circuit boards manufacturing company will be able to offer you a huge variety. You will be able to choose from rigid, flexible, or rigid-flex. What's more, the PCBs will be customized as per the need of the application. 2. Quality Professional and good printed circuit board manufacturing and assembling companies might cost you just a little bit extra but they also guarantee to produce the best results and offer very high quality products. In the end, it is quality that will make the difference between mediocre and a high functioning PCB. 3. Cost Efficiency Since you don't have to waste time or resources on buying equipment to produce the best PCBs or hiring staff to oversee the process, you can actually end up saving money. You can even save on PCB assembly cost by hiring this job out. All you have to do is to negotiate the quote and sit back, relax, and wait for the PCBs to be delivered to you. 4. Eliminate Design Flaws Design engineers hired by PCB manufacturing and assembling companies use the best graphic software to develop and test the schematics of PCBs. This increases the chances of eliminating flaws in the printed circuit boards during the initial design phase. 5. Multilayer PCB Manufacturing and Assembly The process of manufacturing and assembling multilayer PCBs is as intricate as it sounds. All processes of manufacturing and assembling multilayer PCBs require the best machines and trained technicians to pass the quality and functionality tests. Manufacturing and assembling multilayer printed circuit boards yourself is going to cost you a lot. Even the smallest of mistakes during the manufacturing and assembling process might render the entire PCB entirely useless. 6. Save Time PCBs are just a single part of the electronic device. To complete the device, many more pieces would be needed. The manufacturers of the electronic device can hire out the job of manufacturing or assembling the PCBs, which will mean they will have one less chore to do. This, in turn, will save you a lot of time which could be spent on elevating the quality of the product. 7. Experience Experience makes all the difference. It is what makes the name of any company reliable in the market. Long experience of manufacturing and assembling printed circuit boards makes the company well versed in the process and it also makes it an expert to identify design, manufacturing, assembling, and testing needs of certain applications We, at Asia Pacific Circuits, offer these benefits and so much more. For quick turn PCB assembly, PCB manufacturing and PCB designing, you can contact us anytime.

In this study various printed circuit board surface finishes were evaluated, including: organic solderability preservative (OSP), plasma finish (PF), immersion silver (IAg), electroless nickel / immersion silver (ENIS), electroless nickel / immersion gold hi-phosphorus (ENIG Hi-P), and electroless nickel / electroless palladium / immersion gold (ENEPIG). To verify the performance of PF as a post-treatment option, it was added to IAg, ENIG Hi-P, and ENEPIG to compare with non-treated. A total of nine groups of PCB were evaluated. Each group contains 30 boards, with the exception on ENIS where only 8 boards were available.

Printed circuit board surface finishes are a topic of constant discussion as environmental influences, such as the Restriction of Hazardous Substances (RoHS) Directive or technology challenges, such as flip chip and 01005 passive components, initiate technology changes. These factors drive the need for greater control of processing characteristics like coplanarity and solderability, which influence the selection of surface finishes and impact costs as well as process robustness and integrity. The ideal printed circuit board finish would have good solderability, long shelf life, ease of fabrication/processing, robust environmental performance and provide dual soldering/wirebonding capabilities; unfortunately no single industry surface finish possesses all of these traits. The selection of a printed circuit board surface finish is ultimately a series of compromises for a given application.

Stencil printing technology has come a long way since the early 80’s when SMT process gained importance in the electronics packaging industry. In those early days, components were fairly large, making the board design and printing process relatively simple. The current trend in product miniaturization has led to smaller and more complex board designs. This has resulted into designs with maximum area utilization of the board space. It is not uncommon, especially for hand held devices, to find components only a few millimeters from the edge of the board. The board clamping systems used in the printing process have become a significant area of concern based on the current board design trend.
