Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a positioning device for drilling holes in circuit boards. Background Art

[0002] Circuit board is a printed circuit board or printed circuit board, also known as PCB or circuit board. Common circuit boards include single-sided board, double-sided board, multi-layer board, flexible board, rigid-flex board, etc. Circuit board production involves multiple processes such as cutting, drilling, copper deposition, pattern transfer, electroplating, film stripping, etching, etc. Generally speaking, when drilling holes in a circuit board, the circuit board is placed on the drilling equipment. In order to ensure the accuracy of the drilling, the circuit board must be positioned first when drilling. After the positioning is completed, the drilling equipment is started to perform the drilling operation. Therefore, a positioning device is set at the drilling equipment to fix the circuit board. At present, in the case of mass production of a certain circuit board, a positioning device is generally designed and manufactured for the produced circuit board (according to the shape of the circuit board product, circuit layout, etc.), such as setting corresponding positioning pins on the substrate. In this way, when the number of circuit boards produced is small, the targeted design and manufacture of the positioning device will obviously increase the cost and the complexity of the operation, especially when there is only one circuit board produced, the cost of designing and manufacturing the positioning device alone is higher.
