PCB vias are divided into three types: Plating Through Hole, Blind Via Hole and Buried Via Hole. The copper foil traces between conductive patterns in different layers of the circuit board are connected through vias.
The printed circuit board is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components.It is manufactured by electronic printing, so it is named "printed circuit board".
Wanfeng is committed to solving the problem that enterprises have nowhere to process difficult boards, precision boards, and special boards in PCB proofing. It provides customers with PCB proofing of single and double-sided aluminum substrates to meet customers' various PCB proofing needs.
There are many types of circuit boards, which are mainly divided into three categories from the number of layers: single-layer circuit boards, double-layer circuit boards and multi-layer circuit boards.
