Steve, Ed I have also participated in mass addition of wires to fix design issues, without impact to reliability. But the two cents I want to add is that it's OK to do a jumper as a repair for a damaged trace IF you know why the trace is damaged (e.g.. physical damage). If you blindly add jumpers to fix mystery opens in a board then you may be sending walking wounded out to the field to die later. As always: opinions are my own, mileage may vary; contents are hot, not suitable for small children... regards, Graham Collins Process Engineer Litton Systems Canada (902) 873-2000 extension 215 > -----Original Message----- > From: SteveZeva [SMTP:[log in to unmask]] > Sent: Wednesday, March 25, 1998 5:03 PM > To: [log in to unmask] > Subject: Re: [TN] circuit board trace repair > > Ed, > > At a past employer, we built boards for a pretty large networking > company > that went into one of their servers.
