Quality 4 Layer PCB, 4 Layer FR4 PCB,4 Layer Printed Circuit Board-MOKO Technology LTD


The 4 Layer PCB Service is designed for multi-layer circuits. These 4 Layer PCBs include the green solder mask layers and a white silkscreen layer. This is our best value when ordering large quantities of 4-layer PCB boards, having a low per-square-inch cost and quantity discounts.

4 Layer PCB boards have many advantages over double-sided boards. They can be designed more compactly, they greatly improve noise immunity and are much easier to lay out.

Description

4 Layer  PCB  Service boards have top and bottom copper layers with all holes plated through. Sandwiched inside are Ground and Power planes. Through-hole pads can be connected to, or isolated from, the planes. These boards also have top and bottom solder mask layers, giving them a dark green color. On the top surface is a white silkscreen layer showing the component outlines.
