Thermonics & MCT Join Forces to Improve Strip Handling Equipment Efficiency

Posted by Tom Ryan on Jul 12, 2017 1:46:00 PM

Thermonics, a member of inTEST Thermal Solutions with Temptronic and Sigma Systems has developed a portable, low-temperature fluid chiller for MCT Worldwide, Minneapolis, MN (, improving strip handler equipment efficiency. MCT is the leader in strip test handlers for the semiconductor testing industry. The new chiller improves overall equipment efficiency for those customers performing cold testing down to -55 ºC. The chiller has been integrated with MCT’s SH-5000 Strip Test Handler which is widely used for testing of both leaded and leadless semiconductor packages. By delivering low-temperature process fluid to the handler at a higher cooling capacity, the chiller cuts the handler ramp down time to a -40 ºC test point in nearly half the time of previous systems. An automatic fluid purge option eliminates manual draining, decreasing the time to disconnect the chiller from the handler and also minimizing fluid loss during changeover.
