Abstract

This Standard was technically approved by the Assembly & Packaging Global Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on March 26, 2015. Available at www.semiviews.org and www.semi.org in June 2015; originally published June 1998; previously published July 2006.

 

NOTICE: This Document was reapproved with minor editorial changes.

 

This Standard describes procedures for measuring the mechanical, physical, chemical, thermal, and electrical properties of leadframe tape.

 

Equipment, sampling, and procedures are referred to in the individual test methods.

The test methods for the individual properties have been given in this standard.

Ionic impurities (see SEMI G75.1).

Adhesive strength (see SEMI G75.2).

Peel strength of protective film from leadframe tape (see SEMI G75.3).

Water absorption (see SEMI G75.4).

Weight loss (see SEMI G75.5).

Shrinkage factor (see SEMI G75.6).

Thermal decomposition temperature (see SEMI G75.7).

Coefficient of thermal expansion and glass transition temperature (see SEMI G75.8).

Tensile strength, elongation, and tensile modulus (see SEMI G75.9).

Volume and surface resistivity (see SEMI G75.10).

Dielectric constant and dissipation factor (see SEMI G75.11).

Breakdown strength (see SEMI G75.12).

Leakage current (see SEMI G75.13).

 

The methods help tape manufacturers, leadframe manufacturers, and their customers in evaluating leadframe tapes.
