----- Original Message What about liquid Kapton touch-up? Zlatko ----- Original Message ---- From: Kerry McMullen <[log in to unmask]> To: [log in to unmask] Sent: Friday, November 10, 2006 4:10:44 PM Subject: [TN] Power Via Capping Hello Esteemed Technet, Ran into a little issue here. A board we have has 4 power via's (3.3, 5, etc) directly under a device that was not supposed to have an grounded exposed heatsink on the bottom side. The nasty result is the occasional short where one of the power vias make contact to the heatsink. I cannot drill out these vias as there is trace going from these vias directly to the pins of the device. I can use kapton tape to cover the vias, but I was looking for a better solution. No soldermasking allowed! Any ideas? Thanks in advance, Kerry Kerry McMullen Principal New Product Mfg.
