Double Sided FR4 CEM3 PCB Assembly Circuit Board Fabrication Assembly One Stop Service
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.
