ESS and vertical/horizontal vibration test chamber

Environmental Stress Screening

This type of screening is typically performed to ensure product compliance with “Total Quality” dictates and to fulfil two major requirements:

Improve product reliability; Reduce warranty costs. ESS consists in the application of such stimuli as supply and thermal cycles alternated or combined with vibration tests aimed at highlighting those defects that cannot normally be detected by standard inspection or functional tests: contamination, cold or dry soldering, intermittent contacts, bad diffusion, weak connections, insufficient insulation.

The application of ESS techniques is mainly aimed at the ëprecipitationí of latent manufacturing defects and “infantile mortality” through fast thermal cycles (up to 30° C/min. in our ESS chambers with mechanical thermoregulation system, and up to 60° C/min. when using LN2).
