Is normal DI rinse cycle enough to wash away all residue after SMT assembly of high density substrate? This substrate would later be over molded to form MCM module package and I am seeing delamination in high density areas of the substrate at MSL3

Grant, No-Clean paste + IPA = White Residue! #1: Stop using IPA #2: Switch to either a solvent-based de-fluxing chemical or an aqueous-based de-fluxing chemical. If you are using an ultrasonic cleaner for your boards as stated, do not use sapon

I use Simple Green, works pretty well, although I use the concentrate and don't dilute it as is recommended, so it's pretty strong. I am going to try the sugar water though. I'm intrigued.

So, someone is going to get a chance to buy a nice and shiny oven, eh? Summary from my notes of old thread on SMTnet: Some people melt sugar and use that solution to clean cooked-on flux residue. Dissolve sugar into warm water, spray it on the area t
