Breakout Boards and Breakout Sets for Board Testing

Abstract

The invention discloses a switching circuit board and a switching device for testing a circuit board. The switching device comprises a switching circuit board and a detection circuit. The switching circuit board is provided with switching pins, two sides of the switching pins are respectively provided with a first pair of alignment blocks and a second pair of alignment blocks, and two alignment blocks in each pair of alignment blocks are arranged in a mutually separated manner and are connected with the detection circuit. The arrangement direction of the switching pins as a first direction, and a separating gap formed by the two alignment blocks in each pair is arranged along the first direction, so that the corresponding two alignment blocks are connected when pins on a switched circuit board deviate towards the two sides. The detection circuit detects short-circuit and open-circuit states of the two alignment blocks in the first pair of alignment blocks and the second pair of alignment blocks, thereby judging which side of the switching circuit board deviates relative to the switched circuit board, and thus manually or automatically adjusting the position of the switching circuit board so as to enable the switching circuit board to be aligned with the switched circuit board.

Description

technical field [0001] The present application relates to the field of circuit board testing, and in particular to an adapter circuit board and a device for switching circuit boards during circuit board testing. Background technique [0002] In the circuit board test, it is first necessary to use the transfer circuit board to lead out the Pin pin (golden finger) signal of the circuit board under test, and make the gold finger on the transfer circuit board and the gold finger of the circuit board under test one by one correct. Butt on the ground, called the alignment. [0003] At present, we mainly use two methods to realize the alignment of golden fingers, one is the method of mechanical + optics + software, and the other is the blind alignment method relying on structural limit and positioning. Of these two solutions, the design of the former is limited by space, and the cost is relatively high, and the design and debugging of the optical system requires a lot of work, whi...
