Specification :

Double-sided PCBs( Double-sided Printed Circuit Boards) are one step up above single-sided printed circuit board in their complexity.
Double Sided PCBs require plated through holes between top and bottom pads to provide better anchoring for soldered components. This process and the resultant boards allow interconnections between layers through all holes.And meanwhile, most designs require soldermask front and back along with a silkscreen layer for component designators.
We are engage in manufacturing the best possible precision and quality during manufacture processes. If you need more information about printed circuit boards( PCBs) , please don' t hesitate to contact us.
