USE OF HYDROFLUOROETHERS AS TEST LIQUID IN THE TESTING OF AN ELECTRONIC COMPONENT

摘要

The present invention provides a method for testing an electronic component comprising exposing the electronic component to a testing liquid comprising hydrofluoroether that is essentially non-flammable. Preferably the testing liquid is comprised of 90 % by weight to 100 % by weight of the hydrofluoroether. Examples of test methods of electronic components in which the hydrofluoroethers can be used include the testing for the hermeticity of a sealed cavity, a thermal shock test, a liquid burn in test and an environmental stress screening test (ESS).
