Hi Steve Not a dumb question. The short answer? Would it work? Absolutely. Would it be legal per IPC-A-610 class 3? No way. So we could put it on the drawing, except it's a build to print project - we aren't the design authority. The mountain of difficulty involved in getting that approved... And product qualification? Can't claim qualification by similarity on that. So the short answer is that putting an intentional solder bridge there is not an available option at this time. I'm stuck with the world's shortest jumper wire. regards, - Graham -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Steve Gregory Sent: Monday, February 02, 2009 9:05 AM To: [log in to unmask] Subject: Re: [TN] Jumper wire forming for fine pitch QFP? Morning Graham, Can I ask a dumb question? Why not just solderbridge the leads together?

Hello Technet I've got a design where we have to run a jumper between two adjacent legs of a fine pitch part. So the jumper is a tiny piece of wire that runs down the leg, across the foot, bends around in a U, and back up the adjacent lead. We hand form this, and the operators are not liking it. I'm pondering getting the machine shop to try to make something we could use to pre-form the wire for this, but it's a bit higher precision than they usually work to. The gap between component leads is about .012" Does anything already exist in the tooling world to pre-form a wire in this manner? I don't want to re-invent the wheel if I can avoid it. thanks, Graham Collins L-3 communications ES Halifax Production Engineering NOTICE OF CONFIDENTIALITY: This message and any attachments are solely for the use of the individual or entity to which it is addressed and may contain information that is privileged or confidential or controlled technical data that is subject to the laws of Canada or the United States.
