Brick PINFIELD Production Tester (3pcs produced)
The PINFIELD Production Tester was developed for the purpose to evaluate the functionality of LVPS dc/dc converter modules (bricks) with the total quantity of 2700pcs during the serial production. The station provides set of independent low-voltage parametric and functional tests (capacitance tests, input current, LT dc/dc conv. chip functionality, trimming, feedback loop parameters, etc) without powering the brick with dangerous 200Vdc. The PINFIELD station consists of a control box providing supply voltages and measurements features, 10ch voltage scanner (Keithley 2000), LCR meter to measure four brick capacitances (HP4263B), oscilloscope to measure the switching frequency of the converter (TDS224), and a PC computer. The whole tester is fully automated by means of a Labview control program v.7.0, GPIB bus, and USB/RS232 serial link. The test of one dc/dc brick requires only 4 minutes, and about 80% functionality is guaranteed..
