Turnkey Service Rapid - Rate Environmental Stress Screening Chamber
Turnkey Service Rapid-Rate Thermal Cycling Chamber for Environmental Stress Screening
1. Applications:
Environmental stress screening (ESS) is also known as Burn-in, AST (Accelerated Stress Testing), HALT (Highly Accelerated Stress Test), or HASS (Highly Accelerated Stress Screening). No matter what the name is, the idea is the same: create a test program that allows you to eliminate the infant mortality of your products.
KOMEG Turnkey Environmental Stress Screening (ESS) Systems are specially designed to meet a range of ESS testing applications. ESS Systems consist of a test chamber, controller, product fixture, interconnect and wiring, and a functional tester.
Developed to help electronics manufacturers detect product defects and production flaws, Environmental Stress Screening forces infancy product failures that would otherwise occur after final assembly and product delivery. ESS Chambers’ goal is to improve profitability by eliminating defective products. ESS Systems can meet individual performance needs, product loading, and throughput requirements. KOMEG Technology has the experience to provide the best solution for ESS testing at your company.
