Pre-Conditioning Service

Plastic SMD’s and/or non-hermetic solid state devices are subjected to preconditioning tests prior to moving into other reliability testing sequences. Some of the test combinations for these Moisture Tests are:

85C/85%RH, 85C/60%RH, 30C/60%RH

Other options for accelerated soak conditions require 60C/60%RH

Steady-State Temperature Humidity Bias Life (THB) or Cycled Temperature-Humidity-bias Life Test)

 To define and evaluate the moisture resistance on non- hermetic packages and solid state devices in humid environments under high temperature and humidity conditions. This is an accelerated test that causes the penetration of moisture to the device under test.
