You may find some wetting issues running LF HASL with 63/37, as your reflow temperatures will be significantly below the LF reflow. On fiducials...if you don't have a quote for your boards with ENIG, I would recommend at least checking it out. It's

Hello We have a GSM machine with two heads from the universal company, currently the machine fails to zero and in production mode, when the heads increase the displacement speed in the Y axis, they stop immediately. And the error illustrated in the i

Yes, we can't use pure Pb PROCESS. And as I say we will not use it anyway, as we have lead-free BGA's, LGAs, component with Solder Charged Terminations... It's became almost normal practice to solder it with leaded solder pastes. In this case peak re

The first thing I do when looking at a part relative to stencil design, is determine the coplanarity per the data sheet. Ideally your stencil thickness should be equal to, or if needed, greater than the coplanarity. You want the solder paste to com

I am confused about the parameters of the reflow profile needed to solder lead free components. We assemble boards for automotive modules required with leaded solder paste. The boards have ENIG finish. The problem is that I see some wetting issues, v
