Embedded Copper Block PCB
PRODUCT SPEC

Embedded Copper Block PCB

A multilayer embedded copper block PCB for high heat flux and high-current assemblies. The structure embeds copper blocks from one side inside a multilayer HDI board, improving thermal dissipation, saving board area, strengthening the structure, improving reliability, and supporting signal-integrity optimization. Capabilities include 2-30 layers, 0.8-3.0 mm copper block thickness, 3-400 mm copper block size, 3/3 mil inner routing, 3.5/3.5 mil outer routing, 0.10 mm laser vias, and 16:1 through-hole aspect ratio.
