An application note that explores cryogenic and compressor-based cooling for electronic thermal characterization and testing was released by InTest Thermal, Mansfield, Mass. The three factors help determine the cooling method to be used for electronic testing — test specifications, facility resources and cost of using cryogenic vs. compressor-based cooling — are reviewed and explored.
Identifying an optimal cooling method in the design, production and failure-analysis of electronic devices can be a challenge, according to the company. The paper discusses the merits and weaknesses of compressor-based and cryogenic (LN2, LCO2) cooling systems. The paper also evaluates each cooling method with consideration for cost, temperature needs and facility requirements.
