Problems solved by technology

[0002] In the traditional drilling process in the PCB industry, the production of single- and double-sided panels generally adopts the method of first randomly drilling two pin holes in the short side area of ​​the board, and then finding the two pin holes on the bakelite board of the drilling machine by moving the drilling machine spindle and fine-tuning. The position of the hole, drill the pin hole on the bakelite board, drive the pin into the hole, and then transfer the drill tape data to find the zero point for trial drilling. The production process using this method is cumbersome, and it is easy to cause the effective area inside the board Drilling is crooked, which leads to scrapping, and some companies reserve a large size for avoiding crooked drilling, with a single side at least 14mm or more, which affects the utilization rate of the board

Abstract

The present invention discloses a drilling hole positioning method of a single-sided circuit and a double-sided circuit board. The method is characterized in that the method comprises a step of carrying out layout design of a circuit board, and reserving the single-sided dimension of the circuit board to be not larger than 10 mm, a step of drilling two pin holes at the side of the circuit board through a pin machine at the same time, and inputing the coordinates of the two pin holes into the drilling belt material of a drilling machine, a step of drilling two second pin holes with the same coordinates of the first pin holes in an electric wood board through the drilling machine, a step of inserting pins into the second pin holes, and then inserting the two first pins holes to the pins such that the circuit board 1 is fixed to the electric wood board, and a step of setting the drilling belt material through the drilling machine and continuing to drilling holes in the circuit board with the first pin holes as reference points. The operation is simple, the time of moving the spindle of the drilling machine in a machine platform to search the pin holes and a zero position by an operator is saved, and the pins can be quickly hit to carry out a board drilling operation.

Description

【Technical field】 [0001] The invention relates to a drilling and positioning method for single- and double-sided circuit boards. 【Background technique】 [0002] In the traditional drilling process in the PCB industry, the production of single- and double-sided panels generally adopts the method of first randomly drilling two pin holes in the short side area of ​​the board, and then finding the two pin holes on the bakelite board of the drilling machine by moving the drilling machine spindle and fine-tuning. The position of the hole, drill the pin hole on the bakelite board, drive the pin into the hole, and then transfer the drill tape data to find the zero point for trial drilling. The production process using this method is cumbersome, and it is easy to cause the effective area inside the board Drilling is crooked, which leads to scrapping, and some companies reserve a large size to avoid drilling crooked board edges, with a single side at least 14mm or more, which affects ...
