PCB Black Material Custom PCB 2 layer HASL quick turn manufacturer

2 Layers Standard PCB, black material, Surface Treatment is HASL, Copper Thickness is 35UM, Yellow soldermask, white silkscreen, Thickness is 1.6mm±10%mm. Once you have a circuit board design ready it is time for the PCB prototype stage. Prototyping is a crucial stage in project development used to prove the functionality of the circuit. Whether you have made the simplest PCB design or the most complex one, proceeding to production without going through a complete PCB prototype stage is begging for trouble. A lot of tweaks (or corrections) can be applied by modifying an initial PCB prototype but for more major changes and certain circumstances it may be best to just repeat the PCB prototype stage until completely satisfied that mass production of units with matching desirable specifications is likely, so prototype is very important, WMD will show you the actual plate which you can prove.
