Routing tape machining method for circuit board

Abstract

The invention discloses a routing tape machining method for a circuit board, and the method comprises the following steps: S1, setting the number of routing channels and a machining area on a to-be-machined circuit board according to machining requirements, and then dividing the routing channels into odd-numbered routing channels and even-number routing channels; S2, starting the routing machiningfrom the port of the first odd-numbered routing channel of the circuit board through employing corresponding mechanical equipment, directly jumping to the routing machining from the port of the second odd-numbered routing channel after the routing machining of the first odd-numbered routing channel,..., directly jump to the routing machining from the port of the N-th odd-numbered routing channelafter the routing machining of the (N-1)-th odd-numbered routing channel till the routing machining of all the odd-numbered routing channels is completed; S3, starting the routing machining of the even-number routing channels after the routing machining of the odd-number routing channels, and employing the same routing machining mode at step S2 for the routing machining of the even-number routingchannels till the routing machining of all the even-number routing channels is completed. The method can achieve the machining of the circuit board with the small face width and large thickness, solves a problem that there is displacement and size differences during the molding machining of a conventional circuit board, is high in precision of the size of the circuit board, is high in qualified rate, is convenient for production and operation, and is good in performances of products.

Description

technical field [0001] The invention relates to the technical field of circuit board processing, in particular to a method for processing circuit board ribbons. Background technique [0002] With the rapid development of electronic products, people have more and more strict requirements on the design concept of short and compact electronic products, and more stringent requirements on the stability of graphic design dimensions, which greatly increases the difficulty of circuit board design and production. Product Design The smaller the circuit board unit size and the greater the thickness, the more difficult it is for mechanical forming and processing. The two extremely demanding graphic designs are the core technical difficulties in forming and processing. This type of design belongs to the difficult production category in the industry. . [0003] The design size of conventional circuit boards is above 50mm*50mm, and the thickness of the board is designed at a material thic...

AI Technical Summary

Problems solved by technology

Due to the large size of the circuit board in the traditional circuit board forming method, the impact of the gong knife on the dimensional stability of the circuit board unit is less, and there will be no movement of the unit graphics caused by the gong knife aisle, and the circuit board with a size smaller than 20mm*20mm Board, the phenomenon of dimensional deviation and lack of dimensional stability directly caused by molding, leading to product scrapping

Therefore, for some circuit boards with small size and large thickness, when using normal CNC numerical control molding, the problem of large size and displacement deviation caused by the conventional gong belt programming method is a problem that those skilled in the art need to solve
