The electronics industry has been cleaning flux from electronic assemblies since the 1960s when the war in the humid jungles of Vietnam and the critical tolerances of the spacecraft made it necessary to remove any residues from electronics that lead to dendrite growth.
At first rosin-based flux (RA, RMA) was being removed. In the late 1990s low residue flux was introduced which was supposed to be no-clean flux, however, as the size electronics assemblies and semiconductors shrunk, even non-clean flux residue has to be cleaned. In the 2000s, the electronics assembly industry switched to lead-free flux, which resulted in residues that are very difficult to remove.
Banner Chemicals offers a variety defluxing and electronics cleaning products. While we offer world-class cleaning products for electronic assembly, our cleaning products tend to be significant less expensive than our competitors’ products.
