There are several types of bare board electrical testing. Continuity/discontinuity (testing for opens or shorts), insulation resistance (assures sufficient conductor spacing), dielectric withstanding voltage (assures sufficient dielectric thickness), conductor resistance (assures correct conductor cross-sectional area) and capacitance (assures correct dielectric thickness) are some of the electrical tests available. Epec performs all bare board testing according to IPC-9252. Some electrical testing (such as conductor resistance) is difficult to perform and is normally only performed on certain customer specified conductors that have a tight operational range.
