Hi: I'm looking for input from anyone who has experience assembling the MLP package on PCBs. We are experiencing solder opens after assembly, and I'm curious to see how others are processing these critters. The part we are using is a Semtech SH3000

Would like opinions on which brand of leaded water soluble solder has the longest print life. we're currently using Alpha WS-809. Each board goes through the printer every 15 minutes or so, and we wind up re-printing most boards as the solder isn't

It appears to us that the problem lies in the lead-free solder paste rather than the inductors. We have not found a lead-free solder that does not do this. The green is on the copper wire. We believe it gets there during the reflow. The gasses fr

DO NOT Mix Technologies.... If you are using a no clean solder paste use a no clean wave solder process. I have direct experience with using a no clean paste and a RA water-soluble wave solder process. When cleaning with the water wash system your

We have some humidity issues due to monsoon season in southern Arizona, I am having issues with water soluble solder paste, and moisture sensative IC's. We are trying to maintain a 32% relative humidity for EESD purposes. What is the standard, and w

Does any one have the best recommendation for a water soluble solder paste for use with fine pitch parts and micro BGA's and immersion gold pads.
