PCB manufacturing has never been so easy and cheap
Every electronics device is built around PCB. It is an essential part that provides rigidity, thermal dissipation and even brings additional functionality. PCB enables assembling and robustly soldering components. There is no doubt that how good PCB depends on the designer and manufacturing quality. You can make a perfect circuit design, but if PCB is crappy, no manufacturer can help even with the highest precision. All steps from idea to the finished product must be treated with high standards no matter if this depends on you or the second party. PCB manufacturing is a significant step. Depending on board quality, it depends on whether it will be easy to solder if dimensions and holes markings will be within specs. Previous actions influence the automation of further processes of assembly and testing.
