发明名称 Simultaneous pin short and continuity test on IC packages
摘要 An integrated circuit functionality test determining shorts between adjacent pins of all the IC pins while simultaneously determining pin continuity in only three steps. The process includes categorizing all pins of the IC into three sets of pins. One set of pins is connected to digital instruments, a second set of pins is connected to 0 volts, and a third set of pins is left open. The digital instruments sink current in parallel from the first set of pins to identify any shorts of the first set of pins. The process is repeated for each of the other two sets of pins. For IC packages having double and quad terminal positions, each terminal position is treated like a single terminal position, and the measurements of the respective sets of pins of each terminal position is measured in parallel.
