Techneters,
Can anyone help? I am having two problem areas:
1) Blind via holes 16 mil diameter 16 mil deep contacting with 4
inner layers. I cannot always plate copper into all holes. If I do copper
plate them I cannot tin plate all the holes. I have vibrators on the
cathode movement frame and a giant to clout the fight bars with a 2 pound
hammer. Is there anything else I can do?!?
2) Circuits with 2 mil track and gaps. The finish required is
electroless nickel/immersion gold. How can this be done without causing
the tracks to short with nickel spikes?
Thanks in advance,
Roger Hammond
