Double Sided PCB has a raw laminate with a thin layer of copper, applied to two sides of circuit board. Holes drilled through the board allow circuits on one side of board to connect to circuits on the other.
Double Layers PCB expands design capability and reduces physical sizes.
2 Layers PCB becomes the master of the industry for leading the way to higher technological applications, for example, LED lighting, Industrial controls, Instrumentation, Power supplies, HVAC systems, Automotive dashboards, Amplifiers, and Vending machines.
