不在路测试对于新购厚膜块或对其内电路不了解有一定的帮助。厚膜电路的测试,并不需要以接地引脚为基准来测试,而要以与电路连结较多的引脚来做基准点,这样能照顾到电路内大多数元件,测出的数据较为准确。凡厚膜块内含开关管的在测试数据中均标出三个电极的位置,内部开关管可按平时测法来测试判断其好坏。由于IX0308CE及IX0689CE引脚较多,所以选前后级两个基准点分开来测试,这样测试较为 Not on the road test for the new purchase of thick film or circuit does not understand some help. Thick-film test circuit does not need to test the ground pin as a benchmark, but to the circuit with more pins to do the benchmark point, so that it can take care of most of the circuit components, the measured data is more accurate . Where thick film contains the switch in the test data are marked three electrode position, the internal switch can be measured according to the usual test to determine its good or bad. As IX0308CE and IX0689CE more pins, so the election before and after the two benchmark points separately to test, this test is more
