How to Perform HAST Test with a Climatic Chamber JEITA ED-4701/100 103 Method – Tests the durability of semiconductors that are stored or used within high temperature and humidity-based atmospheres.JIS C6 – For testing compact electronic components.JESD22-A118 – Evaluates the reliability of unpowered non-hermetically sealed semiconductor-based devices.– Used for non-hermetically sealed semiconductor-based devices, while powered, to evaluate reliability – Used for accelerated humidity resistance testing of non-hermetically sealed semiconductor-based devices JESD22-A108B – High Temperature Operating Life (HTOL) test.J-STD-002D – Test per resistenza all’umidità accelerata, autoclave non distorto.JESD22-A104D – Temperature Cycling testing to cover component and solder interconnection testing.IEC 60749-4 - Used mainly for semiconductors.IEC 6 - Used for hermetically sealed compact electronic components.There are several standards for HAST tests from the IEC, JESD, JIS and JEITA, all indicating different combinations of temperature and RH, and are used for different situations. These environmental parameters provide an accelerated method of component reliability testing, that quickly finds faults and defects that could emerge during long-term use. If components are tested with power on, in most cases the test is performed with 85%RH. There is also a saturated version of the HAST test that uses a 121☌ temperature and relative humidity of 100%. However this has become less relevant today, due to the new technology used for packaging and passivation materials.īy contrast, HAST test conditions use a high temperature of at least 100☌ and usually around 105☌, along with high relative humidity of around 85%, in combination with a high atmospheric pressure of up to 4 atmospheres. condition, as the samples are subjected to Bias loads. Allthough, time is not the only difference between the two tests: for example, the THB testing holds a 85☌/85% R.h.
