Yins are bad, this guy's serious. Generally, solder pastes are comprised of: 90% solder powder, 5% flux, 4% solvents, and 1% activators [by weight]. Where: * Solder powder, when reflowed, is a metal bonding agent that mechanically and electrically

Hi, I've just splashed out �60 on IPC-A-600F trying to find out the formula for measuring the bow and twist of raw PCB's. Much to my dismay there are 10 lines on the subject in the whole standard. Worse still is that it tells me nothing I don't alre

Cal is correct. Sipad, Precision Pad, Optipad, SSD, and all that were a feeble Euroland approach to creating flat pads for fine pitch assembly. To begin with, they required a complete board redesign using their proprietary software. [Oooo, me firs

Hi, my guys did such solder paste deposits on PCB bareboards before, (before my physical join with my current company), approximately 2-3 years ago, for a small Lot run. What the PCB supplier did was to apply "block" shaped Sn/Pb paste alloy onto t

Thanks for the instructions. I was missing the reflow part... Omikron is the method our board house offers. We have been through the plating thickness problem and tin depletion conditions. Beyond those issues, I have been trying a few different n
