Copper PCB Heavy Copper PCB Hard Gold Metal Core

Copper PCB Heavy Copper PCB Hard Gold Metal Core


Product Details

General description
This is a type of 4 Layer Rogers PCB built on 0.508 mm (20 mil) RO4350B with Tg 280°C for the
application of GPS tracker. Multilayer PCB's on Rogers material have different structure (stack up)
from FR-4 multilayer PCB's, because the core of Rogers material is semi-manufactures. For this 4
layer high frequency PCB, it uses 2 cores of 20mil RO4350B. Usually blind via from layer 1 to layer
3 is hard to be drilled. On the other hand, the back drill technology can solve this problem of signal
