Using a flux pen sounds like a good idea. Comments are: * I assume you�re talking aqueous flux. If not, some NC flux pens leave white residues. Nearly all of 15 samples suffered to varying degrees with white residues. * Use the same flux that you

We use a NC Flux in the wave solder and after aAcelerated Life Test cicle we found contamination white residues paths between some solder points. Does somebody know a possible cause for this contamination.

thank you for the information .We are planning to send the units for analysis.

This is recommended by our EMS to make sure flux is not cheating AOI.

| We are facing a problem of high contamination on boards after wave soldering. We want the contamination to be under 24 ugm/inch square. We are using a no clean flux with the spray fluxer unit of wave soldering. The contamination is higher on the e

Ideally first you need to analyze the residue to see what it is. We had a customer with white residues after wave and elemental analysis revealed tin.

Too many hands in the bucket, unless the owner is one of the engineers. Typically flux is not rated or classified by "feel". What are you soldering? Wires? Components to PCB? What is your cleaning capability or requirement? Aqueous? No-Clean? Ul
