THERMALLY DISPERSABLE SOLDER- ING FLUX

摘要

PURPOSE: To provide a soldering flux which does not leave visible residues on a printed circuit board by constituting the soldering flux of specific weight % of camphor as a flux base, an org. activator and the balance substantially at least one org. diluent. CONSTITUTION: The thermally dissipated cleaningless soldering flux is composed of about 10 to about 20 wt.% camphor as the flux base, about 1 to about 5 wt.% org. activator and the balance substantially at least one org. diluent. The org. activator is formed of aliphat. dicarboxylic acid having about 2 to 6 carbon atoms. The org. diluent is formed of aliphat. alcohol having about 1 to 4 carbon atoms. As a result, the cleaningless flux is provided.
