Okay, 'net is back up. Here are the photos: http://stevezeva.homestead.com/tracedamage_1.JPG http://stevezeva.homestead.com/tracedamage_2.JPG http://stevezeva.homestead.com/tracedamage_3.JPG http://stevezeva.homestead.com/tracedamage_4.JPG It looks kinda' like maybe someone wasn't being careful when they were trimming the leads quite possibly. I've seen nicks in soldermask from someone trimming leads and letting the point of the cutters come into contact with the board as they were trimming them. Or can I ask how the boards were packaged during the last 40-years? Were they packaged individually, or could it have been that they were packaged back-to-back in pairs and the damage that you see on the traces is from the leads of the other board? The little gouges look about the same size as a lead...

The leads are not clinched. Here are a couple of pictures. pat -----Original Message----- From: Steve Gregory [mailto:[log in to unmask]] Sent: Wednesday, March 07, 2012 4:58 AM To: 'TechNet E-Mail Forum'; Goodyear, Patrick Subject: RE: [TN] Damaged board traces, Wow! 40-year old boards and it's the first time they're being used...I guess they really are what you would call legacy boards. Are the leads clinched? Although I don't think it is something with auto-insertion equipment, but you never know. Can you take a couple of pictures? Steve -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Goodyear, Patrick Sent: Tuesday, March 06, 2012 5:34 PM To: [log in to unmask] Subject: [TN] Damaged board traces, Working on single sided legacy boards, I finding half moon rub marks on the traces adjacent to pads, about 0.15" (3.5mm) away. They are circular in nature (half moon shape) on the edges of the traces. Definitely mechanically made. These boards are roughly 40 years old and have never been used. I'm inspecting them prior to installation. Anyone know of any OLD process that could make these types of marks. I have inspected 4 boards and find the same types of deformation on all of the boards although not in the same places. I suspect the boards were originally hand soldered, as there is no solder mask on the runs and they are plated with no excess solder clinging to them. pat ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
