Hello,
I have seen comments regarding z-axis expansion that boards and components
experience during reflow; would any of the gurus care to give some numbers?
Such as the copper in the vias has such-and-such expansion versus a High Tg
FR4 which has such-and-such z-axis expansion. (I am sure someone is going
to correct me because I did not use the correct terms).
Thank you in advance,
David Tremmel
