HIGHLY ACCELERATED STRESS TEST
The Highly Accelerated Stress Test (HAST) is performed at a 141°C temperature and 85% Relative
Humidity (RH) at 2 ATM of pressure with alternate pin bias. This test replaces the traditional
85/85 test and greatly reduces the time taken to evaluate the ability of a plastic encapsulated device
to withstand the long-term effects of a biased humid environment.
PACKAGE INTEGRITY TEST
Package Integrity testing ensures the integrity of surface mount devices in terms of package
cracking, bonding craters, and marked deterioration as a result of heat application during the
soldering operation. This includes testing of 5 units on each 3 legs as follows:
CONTROL
TEST 1
TEST 2
(*PPT = Pressure Pot Testing at 121°C, 100% RH, 2 ATM)
End-points are room temperature electrical test, visual inspection, mark permanency and crater test.
