How to Select a HAST Chamber
When you are looking for a HAST Chamber keep two key aspects in mind: 1. A HAST CHAMBER is a Precision Scientific Instrument - It is NOT a run-of-the-mill Temperature and Humidity Chamber. It is a piece of testing equipment required to perform Highly Accelerated Stress Test under very precise set
A HAST CHAMBER is a Precision Scientific Instrument It is NOT a run-of-the-mill Temperature and Humidity Chamber. It is a piece of testing equipment required to perform Highly Accelerated Stress Test under very precise set conditions of Temperature & Humidity under Pressure. Anyone looking
in the silicone elastomer as contact medium to provide electrical paths between a printed circuit board and a component. In order to assess the reliability of this type of socket, biased, highly accelerated stress testing (HAST) was conducted.
