Not sure why you'd want to immerse an assembled board in 60-70*C IPA for an hour, but I doubt there is much published material on the topic * IPA is toxic * IPA is flammable at room temperature and heating IPA to 60-70*C only makes it more so * There

Alpha UP78 was a modern solder paste. Check with your supplier for recommendations. You're are cleaning some flux residue with the IPA and reducing the leakage current. We're not wild about using IPA. Problems with IPA are: * IPA / material being

regarding dwl comment, "For low volume hand assembly, deionized water or IPA should work fine." Deionized water: Deionized water is corrosive. It needs to be removed. Proof? Drop a copper coin into a covered jar of DI water and watch what happens ov

Hi, We use IPA and Prozone, if IPA is so drastically detrimental, to the pcba's.....what suggested alternative, can you please recommend, as IPA replacement? Thanks.

IPA is a poor choice for a cleaning solvent. * As you mentioned, the flash point of IPA (~12�C TCC). This is sufficiently low that all electrical equipment within a few feet of the bath should be flameproofed or intrinsically safe, if you don't want

Several things to check are: * Ask Multicore if their flux res and your conformal coat are compatible. Conformal coats and NC flux res are notorious for having compatibily issues. * Conformal coat a bare board to determine if there is there is enoug

AJ: Problems with IPA are: * IPA / material being 'cleaned' combination still needs to be removed from the stencil. * IPA and empty containers are a hazardous material by RCRA criteria (40CFR 261) * Flash point (~12*C TCC) of IPA is low enough that a

As a side note: A lot of machine manufacturers call out IPA as a "degreaser". As an experiment put a dab of grease in a container with IPA then put some in a container with mineral spirits. Shake them up and see which one dissolves the grease. It's

Has anyone tried to immerge the PCBA(with ICs, resistors, capacitors,connectors populated) into IPA for 1hr? The temperature of IPA is about 60~70C, is there any damage or degrating found for PCB and the components? Is there any related information s
