Double Sided Board Fabrication

Double Sided Board is a printed circuit board with copper on both sides of Top (top layer) and Bottom (bottom layer), both sides can be wired and welded, and the middle is a layer of insulation layer, which is a commonly used printed circuit board. Both sides can be wired, greatly reducing the difficulty of wiring, so it is widely used.
Both sides of the Double Sided Board have wiring, but to use the wires on both sides, there must be an appropriate circuit connection between the two sides. This "bridge" between circuits is called a pilot hole. A pilot hole is a small hole filled with or coated with metal on the PCB board, which can be connected with wires on both sides. Because the area of the Double Sided Board is twice as large as that of the Single Sided Board, the Double Sided Board solves the difficulty of the Single Sided Board because of the wiring interleaving (which can be channeled through the hole to the other side), and it is more suitable for more complex circuits than the Single Sided Board.

Shenzhen Sky-Win is a one-stop PCBA service provider - Our current focus on the PCBA one-stop supplier schematic design, software development, PCB Layout, a full set of material purchasing, SMT+DIP manufacturing, board direct supply and other OEM/ODM services.
