Abstract:
A board electrical-test method of executing the electrical test of boards, comprising:a conveying process for sequentially conveying the boards downstream one by one with parts mounted thereon facing outward;an electrical-test method of executing the electrical test by positioning the boards while they are conveyed in said conveying process and moving electrical-test probes having contact pins for the electrical test so that extreme ends of the contact pins come into direct contact with surfaces of the boards where the parts are mounted;anda cleaning process using an elastic sheet molded to include dispersed fine metal oxide particles in a specific weight percentage, said process including a first step of piercing the elastic sheet with the extreme ends of the contact pins and a second step of removing the extreme ends from the elastic sheet, with the elastic sheet removing and capturing solder flux from the extreme ends of the contact pins.
