FR4 Printed Circuit Board

Multi-Layer FR4 PCB: BPM19055

As a professional supplier of printed circuit board(PCB), Best Technology is capable of manufacturing the FR4 PCB up to 32 layers and board thickness from 0.13mm to 8mm, here we would like to introduce one of our distinctive multilayer FR4 Boards as BPM19055 with ENIG surface finish.

• 4L FR4 PCB
• Outer layer: 18um copper +25um copper plating
• Inner layer: 35um copper
• Total board thickness: 1.52mm+/-10%
• Soldermask: Green
• Silkscreen:White

In addition to the above points, we also made 5mm rails in the panel as well as 4 positioning holes and multiple fiducial marks. And this board also has impedance control. If the copper thickness and total thickness are not changed, PP thickness can be adjusted. Also, wire width and wire space needs to meet impedance control.
