Hi Jean-Francois, What kind of covercoat is on the flex- Flexible soldermask or kapton/polyimide covercoats? Regards Steve Kelly -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Bissonnette, Jean-Francois Sent: Friday, January 09, 2004 3:33 PM To: [log in to unmask] Subject: [TN] Inner Wall Defect Hi technetters, We recently received flex cables with PTH that have holes blocked by some kind of solder webing. I've asked Steeve Gregory to post them on his web site. I would like to have opinions from the experts out there. Even though the supplier has been asked many times to correct the process the flex circuits often have that defect... Any idea? The pictures are at: http://www.stevezeva.homestead.com under Inner Wall Defect. Thanks!
