Occupational dermatitis from soldering flux among workers in the electronics industry

Abstract

Although numerous occupational irritants and allergens have been known to cause contact dermatitis in the electronics industry, soldering flux is seldom mentioned. Soldering flux used in the electronics industry can cause both irritant and allergic contact dermatitis. Aminoethylethanolamine, a constituent of some fluxes, is a sensitizer. Dermatitis tends to start over the periungual area and spread to the finger shafts and sometimes the wrists. The use of cotton gloves by workers appeared to aggravate the problem. Prophylactic measures are essential to prevent occupational contact dermatitis in workers handling flux in the electronics industry.
