Description
Technical Field
[0001] The utility model relates to the technical field of circuit board inspection, and particularly relates to a jig for measuring pins of a circuit board. Background Technique
[0002] After the production of the circuit board, it is necessary to inspect its performance to ensure the quality of the circuit board and whether the internal circuit is normal. There are at least the following disadvantages in the use of existing measuring jigs: 1. When the existing jig inspects the pins of the circuit board, the circuit board needs to be fixed. Since the specifications of the circuit boards are different, their sizes are also different. The jig should be able to be used for circuit boards of different sizes to enhance its practicability; 2. The pins on the existing circuit board are relatively small. When using a detection pen for detection, bright light should be maintained to prevent inspection errors. However, the position of the traditional lighting lamp is fixed and it is inconvenient for the user to adjust. Therefore, we introduce a new jig for measuring pins of a circuit board.
