Dear Netters:
I have a question. People say that plated through hole is the weak link
in the printed circuit board. What is the data, i.e., when does a PTH
fail (at what temp cycling, at what no. of
cycles)?
For microvias, PTH are often filled and planarized. Is a filled PTH
more reliable? Any data on this? Has anyone looked whether a pure
dielectric vs. filled dielectric vs. a Ag-filled paste make a
difference?
Thanks.
Goran
