IEC 60191-6-1:2001 Mechanical standardization of semiconductor devices - Part 6-1: General rules for the preparation of outline drawings of surface mounted semiconductor device packages; Design guide for gull-wing lead terminals
This part of IEC 60191 covers the requirements for the design rule of terminal shape plastic packages with gull-wing leads; e.g., QFP, SOP, SSOP, TSOP, etc. which are packages classified as Form E in IEC 60191-4. This publication is intended to establish common rules on terminal shapes irrespective of package types.
