Composition for cleaning solder flux remaining in FPCB and cleaning method using the same

摘要

The present invention relates to an alcohol-based compound; Organic amine compounds; Glycol ether compounds; And a sulfur compound-containing solder flux removing composition and a solder-plus cleaning method using the same. According to the present invention, the solder flux of the flexible printed circuit board to which the gyro sensor is applied can be cleaned without damaging the gyro sensor, and the black shield and the underfill attached to the semiconductor mounted on the flexible circuit board can be damaged And the solder flux can be cleaned.;
