Round pads for 0402's. Is it feasible?

While investigating a routing study for a new bga device, I found the vendor used round 20 mil pads on 0402 decoupling caps.This allows fitting the caps between break out vias on their 1mm pitch BGA. Round pad gives about 8 mils diagonally from pin t

This is not strictly a surface mount query but any input welcome I am thinking of using surface mount solder thief pads for a through hole connector. The connector is two rows of 0.1" pitch pins and on waving there is often a bridge on the last two p

Hi all, it has been a bit of a delay but I've finally had a chance to do some further investigation on this. First off, we spend some time to clean the solder bath using Kester Solder Saver and scooped out a lot of crap. We then added about 5kg of

How important NSMD pads are for the QFN and similar packages?

Electronics Forum | Wed Jul 30 00:47:10 EDT 2014 | matusov

Hello gurus, I am a hardware designer with a small company. We are about to send a new PCB for fabrication. This board uses dozens of tiny QFN, DFN, and similar packages. As a final check I have been going through the datasheets of all these parts t

BGA APATURE

Electronics Forum | Wed Nov 05 17:36:12 EST 2003 | Stephen

Make sure that the side of the square is the diameter of the pad, That is that the circle is inside the square not that the square is inside the circle. normally the aperatures are smaller than the pad to get gasketing. In this case the idea is to
