PCB Back Drilling is one of the special controlled depth drilling (NPTH) in the loop of PCB manufacturing process. Normally, there will be various challenges in engineering and production when it comes to PCB design and printed circuit board manufacturing and one of them is how to ensure high performance of retaining signal integrity.
The choice of PCB surface treatment process depends mainly on the type of component that is finally assembled. And the surface treatment process will affect the production, assembly and end use of the PCB.
Silkscreen is one of important compositions to a complete PCB board fabrication, especially it's high importance to finally circuit board assembly. Good work on silkscreen design will be more friendly to PCB manufacturing and assembly.
