Hi Ofer: It seems that an object smashed against the area affected. There is a mark left by an object that collided with the area. Regards, Ramon -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of Ofer Cohen Sent: Wednesday, June 08, 2005 12:12 PM To: [log in to unmask] Subject: [TN] Loose peace of metal - why? Technettters, My QC inspector called me to watch the phenomena showed in the picture that Steve Gregory kindly loaded to his site, and can be found in http://www.stevezeva.homestead.com[Ofer Cohen] (Look for "14 PCB 0402"). This is an extension to the edge trace, but is loose and seems to be breakable. Can somebody tell me why it happened and how to avoid it?
