Abstract
The invention provides an inspection adapter board for printed board, which has inspection electrodes of a pitch wider than electrodes to be inspected, permits carrying out the necessary inspection for a printed board by a tester having a small capacity, and can be designed and fabricated with ease, and a method for inspecting the printed board by an inspection adapter board. The invention also provides a method and apparatus for producing information for fabricating such an inspection adapter board. The inspection adapter board is equipped with inspection electrodes corresponding to the electrodes to be inspected. At least one of the inspection electrodes is a common inspection electrode commonly corresponding to two or more electrodes to be inspected. The common inspection electrode is formed in a state that wiring networks do not form a closed circuit. Alternatively, at least one of the inspection electrodes is formed as a representative inspection electrode corresponding to one electrode to be inspected in each wiring network.
