Abstract
PURPOSE:To improve the efficiency of soldering work by a method wherein a plurality of leads selected from many leads in a flat package-type electronic parts are used as straight leads and the tip sections of the other leads are formed in U shape. CONSTITUTION:A plurality of leads 2a selected from many leads 2 in a flat package-type electronic part having a mold section 1 are used as straight leads and the tips of the other leads 2b are formed in U shape. Then, the straight leads and U-shaped leads are soldered by melting solder going up from through holes under the condition that the straight leads 2a are penetrated the through holes of a printed substrate for positioning. In this way, soldering for parts with many pins are facilitated under the mixed loading condition with other individual parts and working efficiency is improved.
