Does anyone have experience with fabricating/designing boards for ATE
applications at 0.5mm pitch? I have done about 5 boards to date, and all
have been a rollercoaster. It seems that silver epoxy is the only true way
to go, along with several sequential laminations. But with the increase in
laminations comes the slippage of inner layers. Have worked with a few
fabhouses on micro-vias, but this does not seem to be a true alternative yet
as far as cost and time. Truly looking for fabhouses (besides Harbour) and
design techniques that help push this envelope further.
