Thermal Shock Environmental Test Chambers

Product Details:

Purchasing a liquid thermal shock chamber needs close consideration of the long term operating costs. The specialized liquids used can easily evaporate, causing the loss of thousands of dollars of fluid per year, if not properly contained. Liquid-to-liquid thermal shock testing is typically conducted to apply very strong, repetitive thermal stress to test pieces. It can model a product's ability to withstand thermally-induced size changes, crack resistance, hermetic integrity, and changes in electrical properties. This form of testing provides a very rapid temperature shock recovery of conditions, and it can significantly reduce testing time by requiring shorter soaks and less cycles.The TSB thermal shock chambers have been built to meet the demanding test requirements of Mil-Std 883 method 1011.9, which has become a defacto industrial standard for semiconductor devices. 

Serious cost savings:

• ESPEC has led the industry in developing a sophisticated test chamber with multiple mechanisms to significantly reduce fluid usage. The new TSB-51 loses just 1.4 grams per test cycle, or less than a liter of fluid per 1,000 cycle test. The recovery system reduces fluid loss through enhanced airtightness, preventing leakage of evaporated thermal fluid from the test area. A fan draws air to a condensing coil that turns evaporated fluid into a liquid, returning it to the baths. The units also include a separation filter for removing water from the thermal fluid. A refrigerated cooling ring at the top of the hot bath helps limit evaporative losses. 
• Easy to use: The TSB models have also includes our SCP-220TS touch-screen controller, making operation clear and easy.

Product Details:

Through simulation of wind volume and wind speed, TCC-150 can minimize specimen temperature variations, enabling more accurate quick temperature change testing. For specimen temperature, the ramp rate is 15°C/min. For air temperature,the ramp rate is 23°C/min (temperature heat-up average). To maintain a constant temperature change rate for test specimens, the TCC-150 uses a sensor (positioned by the user)for specimen temperature measurement,and a newly-developed high-speed controller that enables highly precise specimen temperature control. This controller enables measurement and control processing at a higher speed than conventional controllers.

Product Details:

• Large-volume test area The test area can contain up to sixty substrates, when set vertically
• Easy wiring access Clear cabinet sides allow easy access for specimen measurement
• Cable ports are provided on the right as well as left sides of the chamber
