WEET Tell the Truth That Some Factories Use Small Chips to Cost Down and How To Test Diode Chip Size

Do you know how to test a diode rectifier chip size? Some low level factory even use very small chips to cost down.  But WEET will never do it. The chip size have great influence on the performance of a diode. WEET would like to show some samples ways to test the chip size. 1, Conduct IFSM surge current...
