Inspection device and inspection method for inspecting connected parts of a plurality of pins to a wiring board to detect a short circuit failure

An inspection method for inspecting a short circuit failure generated at any connected part of a plurality of pins to a wiring board via solder, the plurality of pins being included in a connector provided on the wiring board, the inspection method comprising the steps of:

• connecting a first wiring to certain pins of the plurality of pins and furthermore connecting a second wiring to remaining pins of the plurality of pins;
• connecting an inspection unit to the first wiring and to the second wiring so as to cause the inspection unit to inspect insulation between the certain pins of the plurality of pins and the remaining pins of the plurality of pins;
• and
• measuring a resistance value between adjacent pins of the plurality of pins, wherein:
• it is determined that there is no short circuit failure when the resistance value measured using the inspection unit is not less than a predetermined value, and the inspection unit confirms insulation between the certain pins and the remaining pins, and
• it is determined that there is a short circuit failure when the resistance value measured using the inspection unit is less than the predetermined value, and the inspection unit confirms conduction between the certain pins and the remaining pins.
