Quality is more than a word

Key technology for ensuring reliability Supports the current trend toward higher stress. High accuracy is increasingly demanded in the pursuit of reliability in the field of electronics. “Liquid-to-liquid” type thermal shock testing is now attracting attention for its ability to impose higher thermal stress on specimens than “air-to-air” type testing, and to deliver test results quickly. ESPEC has successfully developed next-generation liquid-to-liquid thermal shock chambers that satisfy the demand for environmental conservation and lower running costs from brine and power consumption,...

Utility A number of mechanisms for drastically reducing brine consumption To reduce br i ne consu mpt ion, t he airtightness of the test area has been enhanced to prevent vapor leakage and brine evaporation. Numerous mechanisms have also been adopted, including a water separation filter for removing brine from water for the purpose of brine recycling. As a result, these new chamber models have reduced brine consumption by approximately 65 compared to the preceding model (TSB-5). Both single-liquid and double-liquid brine applicable Either single-liquid brine or doubleliquid brine can be...

Comparison of power consumption Conditions : 20 cycles H : 155 L : 70 Specimen : TSB-51 TSB-5 Energy savings achieved Dramatic energy savings have been achieved through the adoption of a new r ef r ige r a t io n c i r c u it , w it h p owe r consumption slashed by as much as 52 (compared to former ESPEC models). 10.0 *Above values are references. Installation environment improved through reduced operation noise 20.0 The operation noise level of the chamber has been reduced to as low as 65 dB (A-characteristic) by providing soundproofing panels for the noise-emitting machine compartment,...

Control operation Visibility and ease of use improved through interactive input using a touch-screen system and color LCD screen Uses a color LCD interactive touchpanel system employed throughout the Thermal Shock Chamber Series A color LCD panel design allows settings to be made simply by touching the screen in accordance with the display. The test pattern, test area temperature, number of temperature cycles, trendgraph display, etc., are all displayed on the screen. Setting system Interactive input system using a touch panel Color TFT LCD panel (6.5 inch) • Test area exposure temperature...
