Apparatus and method for evaluating the surface insulation resistance of electronic assembly manufacture |
摘要 |
A test vehicle for an SIR testing system is described. A circuit board having a plurality of interleaved circuit patterns is provided with replica components mounted thereon. The interleaved circuit patterns have different conductor spacings to permit a qualitative evaluation of electronic assembly manufacturing processes. The replica components have connection leads which are soldered to circuit pads on the circuit board. The circuit pads are connected into two groups which are used along with the interleaved circuit patterns to evaluate the manufacturing process using SIR measurements.
