Abstract
The invention relates to a method comprising supplying a test signal to a first pad part of the pad; measuring the occurrence of the test signal through a second pad part of the pad or a part of the printed circuit board connected to the second pad part, which second pad part is separate from the first pad part, and the leg of the connector is fastened both to the first pad part and to the second pad part during the manufacturing process in order to establish a connection between the pad parts through the leg. The invention further relates to a printed circuit board.
Claims45
A method of checking the fastening of a connector fastened by its leg to a pad of a printed circuit board, the pad comprising a first pad part and a second pad part separate from each other, the method comprising
- supplying a test signal to the first pad part of the pad,
- the leg of the connector being fastened during the manufacturing process both to the first pad part and to the second pad part in order for the test signal to pass along the leg of the connector from the first pad part to the second pad part, and
- measuring the occurrence of the test signal through the second pad part of the pad.
A printed circuit board comprising:
- at least one pad comprising a first pad part and a second pad part separate from each other;
- at least one connector comprising at least one leg fastened to the pad;
- wherein
- the leg of the connector is fastened both to the first pad part and to the second pad part in order to establish a signal path for a test signal from the first pad part to the second pad part;
- the first pad part is an input point of the test signal to which the test signal can be supplied;
- and
- the second pad part is a measuring point of the test signal from which the passing of the test signal along the leg of the connector from first pad part to the second pad part can be measured.
