• China Printed Wire Board Custom PCB Board 10 Layer PCB

    When your PCB needs six layers of routing you should choose to use ten layers of PCB. Because ten-layer circuit boards usually have six signal layers and four planes. Of course we do not recommend the design of more than six signal layers on the 10-layer circuit board. Ten layers are also the largest number of layers which can be easily manufactured on 0.062 inch thick sheets.
