Copper surface treatment for CO2 laser direct drilling
This laser direct pretreatment effectively removes copper splash or burrs produced in CO2 laser direct drilling.
MEC PowerETCH
HE-7002A
This laser direct pretreatment effectively removes copper splash or burrs produced in CO2 laser direct drilling. This pretreatment, applicable for horizontal process lines, can remove the rough surface at the bottom of via holes (mat surface) formed on the core layer of any-layer substrate.
Deburr etching
Why deburr etching is necessary?
If copper splash is not removed before plating, abnormal depositions of plated metal may occur, causing conduction failure. To prevent this, deburring microetching is necessary.
