Abstract :
We measured the creepage breakdown characteristics of printed wiring boards in silicone gel in three types of specimens, one each with and without a background electrode, and one with a background electrode but without a surface earth electrode. The relationship between creepage breakdown voltage and creepage distance was obtained for the specimens with a surface earth electrode and with and without a background electrode. The breakdown voltage of the specimen without a surface earth electrode was separated into substrate surface perimeter and substrate side components
