Our assembly group used to pitch a fit if the traces didn't come out of the ends of the pads, ---[] []--- , not the sides, not the corners. They said it caused tombstoning. When confronted to produce a board with this tombstoning, they couldn't. They subsequently changed the rule so we could use sides and corners to exit, and there have been no additional complaints. Any assembler, captive or independent, will not change unless you force them to. They would rather use proven methods and not expend time, materials, resources, and MONEY to improve their process. -- George Patrick Tektronix, Inc. Central Engineering, M/S 39-512 P.O.

It's fine for a vendor to take a position such as this - but they really need to justify it when they do. We do it all the time without any problem. -----Original Message----- From: john wheeler [mailto:[log in to unmask]] Sent: Wednesday, August 07, 2002 10:22 AM To: [log in to unmask] Subject: [DC] PREFERED TRACE DIRECTION INTO PAD We had a board reviewed by an assembly company that said traces should not come out the corner of chip resistors and capacitors (45 degrees). I thought that this was I good way to keep trace lengths shorter. What problems does this cause coming out of the corner? Is a side or end the preferred way?
