Overview

IEC 60191-6:1990/AMD1:1999 is Amendment 1 to the IEC mechanical standardization series for semiconductor devices. It updates Part 6, which defines general rules for preparing outline drawings of surface-mounted semiconductor device packages. This amendment specifically adds two TSOP (Thin Small Outline Package) family drawing templates - TSOP Type1 and TSOP Type2 - and their recommended dimensional values and notes (Annexes A.5, A.6, B.2 and B.3).

Key topics

• Outline drawing rules: formalizes how to present package outlines, datums and reference planes for surface-mounted device (SMD) packages.
• TSOP package definitions: new annexes include detailed figures and definitions for TSOP Type1 and TSOP Type2.
• Datum and planes: definition and application of datum A, seating plane, and base plane used in mechanical drawings.
• Terminal geometry: terminal cross-section, length of soldered part (Lp), terminal width (b, b1), and plating details (Pb/Sn, Pd) with recommended thickness and tolerances.
• Pitch and coplanarity: terminal pitch (iei) options, positional tolerances (including Maximum Material Condition, MMC), and allowable coplanarity for solderability.
• Index area and positional areas: rules for index mark placement and terminal position areas (l2 max, b3 max, etc.).
• Recommended dimensional tables: Annex B includes recommended nominal and limit values for mounting/interchangeability and gauging (examples: E × HD families, L1, ZD formulas, standard terminal counts).

Applications

This amendment is practical for professionals involved in the mechanical and PCB aspects of semiconductor packaging:

• Package designers creating TSOP outline drawings and mechanical specifications.
• PCB layout engineers ensuring pad patterns and clearances match standardized package outlines.
• Test socket and tray designers using recommended L1 / G1 dimensions for mechanical fixtures.
• Component manufacturers and assembly engineers for consistent terminal plating, coplanarity, and solderability requirements.
• Quality and standards teams ensuring interchangeability and compliance with IEC mechanical rules.

• This document is part of the IEC 60191 series (mechanical standardization of semiconductor devices) and was prepared by IEC TC47 / SC47D. For full compliance work, consult the full Part 6 text and other IEC 60191 parts for related package families.
