Durable Environmental Stress Screening Test Chamber
10℃/min Ramp. Rate Temperature Change ESS Chamber
Rapid Temperature Change Test Chamber / ESS Chamber introduction
Environmental Stress Screening Test Chamber, also name as ESS chamber, Rapid Temperature change rate test chamber, is to change the external environmental stress by using the temperature acceleration technique (the product produces alternating expansion and contraction when circulating in the upper and lower extreme temperatures) under the design strength limit, so as to generate thermal stress and strain in the product.
Sanwood Rapid Temperature Change Rate Test chamber is applied to find hidden mechanical weaknesses in electronic components when test specimens are exposed to rapid temperature change conditions.
