Hmm. Then how are other users of this connector doing it? This seems like a generic problem. The solder technique is generic afaikt. 1. Either they are using smaller width tracks and are passing between the left hand pads. 2. They have via's right to the pads. But that's very close to the edge. The options I see... . find other schematics using this connector. . Use smaller width tracks. . Cut the pads tight a little shorter and place the via's to the right creating a bottleneck but stil far enough from the edge . The above but to the left, via's in the middle. > > _______________________________________________ arm-netbook mailing list arm-netbook@lists.phcomp.co.uk http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to arm-netb...@files.phcomp.co.uk
