Residue Effects of Weak Organic Acid (WOA) Flux Activators

Flux chemistries that are not properly activated or cleaned is the most common source of detrimental ionic contamination.

In this article, you’ll learn:

• The three categories of residues containing WOA flux activators.

• The best practice use of each WOA flux activator.

• The reason unreacted fluxes pose a reliability threat.

Varying flux chemistries require different cleaning protocols and ionic contamination limits.
