How PCBs are made – the basics

PCB manufacturing is an important step towards the successful build of electronic equipment. The printed circuit board may influence the device’s quality and smooth operation – if it is well built, the device works as planned, and if it has flaws, it may bring some deviations from normal operation. Anyway, billions of electronic devices worldwide, and all of them use PCBs as the basis for circuits. Earlier devices were larger, used lots of through-hole components, but today in the modern world, electronics is very miniature and dense. Thus PCBs become much more complex, requiring more and thinner tracks, more layers, and should work on high frequencies. So, PCB designers have a tough task, but a PCB manufacturer should follow the trends. But despite the requirement change, the whole process of PCB manufacturing remain practically the same.
