Hi, I curently have an interesting challenge. But I don't have all the knowledge to solve it. One of our boards is used in RF applications. We noticed that the No-Clean flux residue makes interferences in the RF signal. Removing the flux residue so

Does anyone have any data or experience with voids in Glob Top applications? We are working with a RF application and I'm trying to find information on RF performance characteristics and moisture absorption on a glob toped devices. We have determined

im running some tests at the moment for hand soldering using a no residue water based flux from MBO, called WBF-01. leaves a good clean finish.

Does anybody out there have any special insights into utilizing no clean paste in high frequency RF applications? I would imagine there may be some issues with solder balls that would affect functional test (Earl, do you have something for me here?)

The propensity for flux residues to cause shorts can be increased in humid environments where water molecules hydrate the surfaces. At high frequencies, electrons travel on the surface of conductors/insulators, increasing the likelihood of shorts in

Comments are: * Sounds like it's necessary to clean "heareous F381, F352 no clean solder paste" in your application. Consider a paste that may be better suited to your application. * If you're cleaning "low residue flux", consider using an organic ac

Residues from different no-clean fluxes produce different levels of variation in RF circuits. Some no-clean fluxes work fine. Following this, a no-clean flux can produce different levels of variation in RF circuits depending on the process setup.
