SEMI G42 - Specification for Thermal Test Board Standardization for Measuring Junction-to-Ambient Thermal Resistance of Semiconductor Packages -

Abstract

This Document provides the requirements for a standard thermal resistance test board to be used in junction-to-ambient thermal resistance measurement of a semiconductor package under still- and forced-air condition as a referee method.

This Document describes the thermal resistance test board for measurement of the following packages:

• Dual-In-Line Packages (DIP),

• Plastic Chip Carrier Package (PCC),

• Quad Flat Package (QFP),

• Pin Grid Array Package (PGA), and

•Ball Grid Array Package (BGA).

This Document uses SI units.
