Thermal Shock Chambers


Thermal Shock Chambers - Air to Air
ESS (Environmental Stress Screening) Chambers
The TSV, TSH, TSD Series

What is ESS?
ESS는 육안 검사 또는 전기 검사로 감지 할 수 없는 결함이 있는 부품이나 공정 문제와 같은 결함을 밝혀내는 검사 제품의 하나 입니다. 전자제품의 제조과정에서 제품의 결함과 제작 과정에서의 결함을 밝혀 내기 위해 계발되었으며 파손을 밝혀 내기 위해 열 사이클링과 진동을 이용합니다. Environmental stress screening chambers은 제조과정이나 신제품의 시험에 사용 가능 합니다. Russells사의 air-to-air thermal shock chambers는 전세계에 설치되어 오늘날의 environmental stress screening의 요구조건들을 충족시키는 것을 입증하고 있습니다. 자사의 고온과 저온 사이의 직접적인 변환 이론은 열 충격 또는 빠른 온도 변화가 있는 부분을 획득하는데 경제적인 이론입니다.
 
Thermal Shock Chambers
Russells air-to-air thermal shock chambers are available in three configurations:
  • TSV Series Two Zone (hot/cold) Vertical - direct hot/cold transfer
  • TSH Series Three Zone (hot/ambient/cold) Horizontal - direct hot/cold transfer with selectable ambient temperature dwell required for some MIL-STD's.
  • TSD Series Double Duty (hot/cold/hot) - direct hot/cold transfer with additional hot zone and second transfer carriage effectively doubles throughput capacity for high volume production.
  • Sizes from 30 l (1 cu ft) to 450 l (16 cu ft) capacity
  • Cold zone temperatures to 73° C (-100° F)
  • Hot zone to 200° C (392° F)
  • Automatic transfer of test specimens between zones
