Thick Copper Etching

Thick Copper Etching

The trend of thickness of conductor shows decrease against finer pitch routing because TAB/COF was used mainly for low power electronics.
On the other hand according to the progress of intelligent power devices, customers have started to demand thicker copper traces for improvement of current allowance and heat dissipation capability.

FLEXCEED developed thick copper etching technology which makes high aspect ratio possible with thick copper materials.
