I. Introduction: three slot thermal shock chambers without the use of liquid gas (LN2LCO2) auxiliary cooling, completely still analyte test mode is the current electronic components testing, research and semiconductor production line with a large number of screening can save a lot of testing supplies costs. Quick operation, high reliability, is the company after years of concentrated effort to research and development of high-performance test machine, providing you with a long-term reliable test tool. Second, the main characteristics: (01) test tank completely still, by the applied load test hole wiring; (02) Storage System can prevent users from occupational injuries; (Note: The exhaust gas generated by the liquid, into the lungs causing pulmonary Ministry to reduce the amount of oxygen, and produce burnout, lack of concentration, etc.); (03) color LCD with touch-type man-machine interface controller, simple operation, easy to learn; high (04) Royal precision temperature system, all using PID automatic calculation imperial system; (05) to select the start position, high or low temperatures to start the cycle; (06) has an appointment start function; (07) and can be set to automatically defrost cycles; (08) to select two or three slots slot cyclic thermal shock chambers; (09) operating status display; (10) there is an exception or fault display and troubleshooting instructions; (11) pneumatic valve easy to open, to ensure airtight and off thermal protection Third, the principle diagram of four.
