LEAD FOR SOLDERING GULL-WING LEAD PACKAGE SURFACE MOUNT COMPONENT

摘要

PURPOSE: To enable properly and surely soldering the lead for soldering a gull- wing lead package surface mount component, by performing bending work at the tip of the lead for soldering the gull-wing lead package surface mount component. ;CONSTITUTION: In the lead for soldering a gull-wing lead package surface mount component, base metal 2 is coated with fusible alloy 1, and bending work is performed at the tip of the base metal 2. Thereby, the rupture surface on which an oxide film of the tip end surface of the lead for soldering a conventional gull-wing lead package surface mount component is formed is not directly soldered, and soldering is performed on a bent corner part coated with the fusible alloy 1. Hence, solder wetability is improved, and solderability to the soldering lead of the gull-wing lead package surface mount component and the long term guarantee of soldering quality are enhanced.;COPYRIGHT: (C)1995,JPO
