Problems solved by technology

The fixing method of the double-sided board makes the drilling accuracy of the double-sided board depend too much on the accuracy of the clamping PIN slot. The loss or aging of the clamping PIN slot has a great impact on the accuracy of the double-sided board. In addition, when the double-sided board is planted with pins, it also depends on the size of the PCB board. Differentiate for debugging

Abstract

The invention discloses a PCB drilling positioning method. The PCB drilling positioning method includes the following steps that as for a pre-drilling belt, the following substeps are set and include that a first positioning hole, a second positioning hole and a third positioning hole are drilled, the connecting line between the circle center of the second positioning hole and the circle center of the first positioning hole is perpendicular to the connecting line between the circle center of the third positioning hole and the circle center of the first positioning hole; as for production drilling belts, the following substep is arranged and includes that three board holes corresponding to the pre-drilling belt are drilled; a bakelite plate is mounted on a numerical control drilling machine; the numerical control drilling machine drills out three fixing holes, corresponding to the pre-drilling belt, in a multi-layer board or a double-sided board according to the pre-drilling belt; and then the numerical control drilling machine drills out three drilling positioning holes in the bakelite plate according to the production drilling belts, the three fixing holes correspond to the three drilling positioning holes, and therefore the multi-layer board or the double-sided board is fixed onto the numerical control drilling machine. By means of the PCB drilling positioning method, seamless switching between different types of boards and different part numbers can be achieved on the same equipment, the production efficiency is improved advantageously, and the accuracy of PCBs is not affected by external equipment.

Description

technical field [0001] The invention relates to the technical field of PCB board production positioning, in particular to a PCB board drilling positioning method. Background technique [0002] Now the PCB industry adopts different CNC drilling positioning methods for different types of PCB boards. The traditional positioning method is: the multi-layer board is designed with Mas blue holes, which are transferred to the inner core board through the inner layer, and the positioning hole is formed by pressing the target, and then fixed on the bakelite board of the CNC drilling machine to realize the positioning. For the double-sided board, pins are pre-planted on the board, and then the pins are inserted into the clamping PIN slots on the table of the CNC drilling machine to achieve positioning. [0003] These traditional positioning methods are very inconvenient when switching between different board types and different material numbers. When converting between multi-layer bo...
