Multitest, a designer and manufacturer of final test handlers, contactors and load boards used by integrated device manufacturers (IDMs) and final test subcontractors worldwide, announces that its MT9510 x16 has proven its outstanding temperature accuracy of +/- 2.0°C at an Asian high-volume production site. The company always applies the strictest measurement methods for indicating temperature accuracy, i.e. the figure stands for the dynamic temperature accuracy measured at the device under test (DUT) for the entire test time. In this case the measurement was for cold and hot test of QFN 4×4 and QFN 5×5 packages during a test time of three minutes. The system ensures that even for 16 site test the packages are tested really under the required temperature without compromise. The challenge is to maintain the pre-soaked temperature from the soaking area while the package is inserted and contacted. This only is possible with advanced temperature control at the contact site during test. Based on its field proven experience with the MT9510 XP, Multitest combines advanced mechanical design features and leading thermal control processes to achieve this highly reliable temperature performance for high parallel test.
