Hi, The guys here have some boards that have been reworked however as we use no-clean paste we are getting the white residue after ultrasonic cleaning. We are using an alcohol based cleaner in the ultra sonic cleaner. Does anyone have any ideas, or

if two boards with different solder masks give different results on flux residue level after soldering with the exact same machine settings than it is clear that one of the solder masks is not compatible with your no-clean flux. could be the solder m

Matt solder mask finishes gives the widest process window in view of potential amount of residues when using No-Clean. Shiny (glass like) finishes are more sensitive to residues due to lower surface area compared to matt finish. If the shiny finish i

Hi all How can I find the technical paper or source of information about using No-clean flux with high frequency apllication. High frequency mean more than 2 GHz - 5 GHz. I heard from my colleague that No-clean flux residue on board effect to high

Omid, No-clean fluxes need to be used right out of the can without thinning. In the past with RA and RMA fluxes you could adjust or thin them to your desired density because they had plenty of solids up to 30%. No-Clean fluxes have a lot lower solid
