Abstract
Provided is a circuit board including an inspection terminal, the circuit board including: a connection terminal, which is arranged on a front surface or in an inner layer of the circuit board and is electrically connected to an object to be inspected; an inspection terminal configured to measure a resistance value of the object to be inspected; and a connection wiring configured to electrically connect the object to be inspected and the inspection terminal to each other, the inspection terminal being arranged on a side surface of the circuit board, at least a part of the connection wiring being formed on a back surface or in the inner layer of the circuit board.
Claims19
A circuit board, comprising:
- a connection terminal, which is arranged on a front surface or in an inner layer of the circuit board, and is electrically connected to an object to be inspected;
- an inspection terminal configured to measure a resistance value of the object to be inspected;
- and
- a connection wiring configured to electrically connect the object to be inspected and the inspection terminal to each other,
- the inspection terminal being arranged on a side surface of the circuit board,
- at least a part of the connection wiring being formed on a back surface or in the inner layer of the circuit board,
- wherein the connection wiring comprises a first connection wiring, a second connection wiring, and a third connection wiring,
- wherein the first connection wiring is arranged on the front surface of the circuit board,
- wherein the second connection wiring is arranged in the inner layer of the circuit board, and
- wherein the third connection wiring is arranged on the back surface of the circuit board.
