heavy copper based 200W/m.K high thermal conductivity multilayer layout clad pcb manufacturer
1. Product introduction:
The construction of a heavy copper circuit endows a board with benefits such as:
●Increased endurance to thermal strains.
●Increased current carrying capacity.
●Increased mechanical strength at connector sites and in PTH holes.
●Use of exotic materials to their full potential (i.e., high temperature) without circuit failure.
●Heavy copper plated vias carry higher current through the board and help to transfer heat to an external heatsink.
●On-board heatsinks directly plated onto the board surface using up to 120-oz copper planes.
●On-board high-power-density planar transformers

6. FAQ:
Q.Which type of PCBs do you expert in?
A:We are specialized in producing HDI multilayer blind, BGA, impedance, half-hole, double-sided, single-sided, etc.
A:We are OEM on PCB boards with experience over 12 years.
Q.What is your Lead time?
A:Lead time is usually punctual here, for some special situation, we can also advise customer in advance to avoid any inexpectation or loss at customer side.
Q:.What is your testing policy and how you controle the quality?
A:For sample, usually tested by flying probe; for PCB Volume over 3 square meters, usually tested by fixture, this will be more faster. Due to there’s many steps to PCB production, we usually do inspection after every step.
