Nooo, Joyce is not counterfeiting. She can do a lot of wonderful lab stuff, but that is not something she practices at or for RIM.

Imag is. Chem process. Control by solution composition, ph, etc. It is self limiting. If done properly, it could be on site. I did plate a copper coin using just the stuff your vendor mentioned. However, I did check conc, ph, temp, surface cleanliness, etc. Make sure he take the waste with him if you allow him to set a foot in your plant. Good luck. -------------------------- Sent using BlackBerry ----- Original Message ----- From: TechNet <[log in to unmask]> To: [log in to unmask] <[log in to unmask]> Sent: Tue Nov 11 22:46:51 2008 Subject: [TN] Repair to ImAg plating? Hi everyone, We have an issue with loss of plating adhesion on some ImAg finished PCBs. The affected area is small and consistent in location across the PCBs with the defect. All other areas seem to be ok when tested per a tape test. The PCB supplier is proposing to visit and "repair" them here at our site. I was not even aware plating could be repaired, let alone away from a PCB fab shop without plating lines etc. Is this even possible? I am very hesitant, as I very seriously doubt the control and/or quality of the "repair" process. At the very least, how would thickness be controlled? We specify micro 5-12 inches in thickness per IPC-4553, and the overall PCB is to meet IPC-6012 Class 3. Anyway, they described the process as follows: I will send you the solution by Fedex in a small bottle. Once you have received it, I will come to your facility and repair the boards. I will need a hot plate and Pyrex container to heat-up the solution to 120 F. Do you have these two items? Otherwise I will bring them with me. I will clean and repair the boards locally. Once it is done, I will do the tape test to make sure the adhesion of the silver is adequate. My little voice is screaming "NOOOOOOOOOOOOOOOOOOOOOOO!!"
