or something that retards the copper plate up.
Not necessarily a problem, not pretty but not a problem if the hole walls are good.

If you section is the copper plate height requirement met?  If yes and they passed E test then they are good.

Did you get a micro section report with your certs?  Again, good micro section, good e test they are good, Hole walls have etch out, not so good.

that's my 2 cents,
Chuck

Hi Ong Seet Leng,

Looks like there was some sort of problem with the etch resist, can't say exactly what that was though. I definitely would be kicking these back to the vendor!
