Brian: SMTnet has a "Terms & Definitions" section in the "Library." OA Flux. Flux, Organic Acid. A water soluble flux. Good luck Dave F

150º de-ionized water, however, if you're doing hobby work at home, regular hot water will be fine. Just be sure to allow the water to dry sufficiently before powering up the board. You can also use IPA or a custom flux cleaning solvent available o

Does anyone have any info in regards to wearing gloves, finger cots in a no-clean process? Are there ionic contamination levels that validate the costs involved in setting up a system? Appreciate any feedback -Rich

Definitly evaluate the TD washer smt 324 / 318. I have two units and they have been fantastic from a maintenance point of view. Small, quiet and easy to maintain. I am in the middle of cleaning capability and ionic contamination testing as we spe

Hi Rob, I must take issue with your statement �By definition, no clean solder can be not-cleaned�. All no-clean fluxes can be cleaned. Whether or not one cleans no-clean depends on a variety of factors. More than eighty percent of all post reflow

Sean, We suggest having the PCB tested for ionic cleanliness. It is conceivable that though the visible flux residue has been cleaned, there is still invisible, yet ionically significant residue in the area of the board/part. We also suggest ensur

Hi, Is the limit for " 10.07 " for assemblies ? I guess we need to calculate how much ionic residue the boards see after assembly and cleaning. and then calculate back to the board spec if i am not mistaken ? For bare fabs we have to access the li

water alone especially cold is not good enough, how do you check for hasl fluids when most residues left behind after improper cleaning are non ionic. Use 40C saponifier followed by heated rinse then cold rinse then DI rinse followed by dry.Nylon bru

I'd like to follow the thread discussed on assembly. Hope Everyone is ok with that. I do run into the problem (have it now) that Ionic cleanliness is requested by print on a no-clean assembly. My intention is to use the no-clean to skip the aqueou

If No-Clean flux does not need to be cleaned, then why do I get readings of up to 27(ug NaCl/sq in) on boards that are not washed, up to 23.4(ug NaCl/sq in) on boards washed with DI water only and from 1.2 to 10.1(ug NaCl/sq in) on boards washed with
