Pardon me for being so bold, but I still cannot understand to this day why solder paste thawing is an issue. I am not sure what types of paste you all are using but it has been my experience that the only thing you gain by refrigerating is 3 months

Stepped stencils are usually the result of some dumb customer's requirement. 2 examples I can give: 1.) Customer demanded 50% wick-up the termination of a MELF component. No way you can get that from reflow. Played around with a drastic "step up

What are the long term issues with high tin content solders on parts plated with silver over copper? Is it possible that the silver will be absorbed by the solder then over a long period of time the tin will react with the copper causing it to part

Hi russ, I am in the process of developing a "hybrid" reflow profile to solder a board that has LF BGAs and leaded solder. Have you encountered a similar situation before? if so what was the "safe" top side temp for the leaded components that was set

I have read an interesting article on pip plus, where they say "However, both PIP processing and the use of solder preforms are well-proven methods. The combination of pin-in-paste plus solder preforms delivers numerous benefits compared to a combi

Due to spacing issue, we are considering using power bricks with tin/lead solder ball instead of PTH package. The solder ball is 40 mil diameter. Our CM suggested they do hand place since the pick and place nozzle cannot pick up and hold the part due
