Subject: [TN] Different pad sizes on the same BGA
Dear Technos,
Due to a highly restrictive design, we have a 1mm pitch, 17x17mm BGA
that has 250 micron pads. As per a previous posting of mine, these pads
peel off during depanelizing.
In reply to my request to increase pad size, the designer could do the
following:
* Modify the first row of pads to rectangular shape, 250x350 um
* Increase all the other pads to 350um circular pads
How does this look from the reliability point of view?
It's a medical imagery application, not a life supporting device but
best reliability expected. It will work in hospitals, so relatively
stable environment.
Thanks,
Ioan
