One-time routing forming method for printed circuit board

Abstract

The invention discloses a one-time routing forming method for a printed circuit board. The method comprises the following steps: manufacturing a circuit board outline frame according to customer requirements; preparing routing tape data, matching router bits with different specifications and sizes according to the size of an inner groove of a circuit board design, manufacturing an inner groove routing tape by adopting an anticlockwise G41 left compensation mode, and manufacturing a peripheral routing tape by adopting an anticlockwise G42 right compensation mode; outputting the routing tape data; fixing a circuit board needing to be processed to a router table; and according to the model of a circuit board product needing to be machined, calling corresponding routing tape data and setting the working parameters of a router and routing compensation values, wherein the compensation value of the inner groove routing tape ranges from minus 0.04 mm to 0.06 mm, and the compensation value of the peripheral routing tape ranges from 0.05 mm to 0.1 mm; and conducting routing and forming. According to the one-time routing forming method for the printed circuit board, one-time routing forming is achieved on a machine, production efficiency is high, and processing cost is low.

Description

technical field [0001] The invention relates to the technical field of printed circuit board production, in particular to a primary gong board forming method for a printed circuit board. Background technique [0002] With the development of electronic technology products, the demand for printed circuit boards has been increasing, making printed circuit board enterprises also develop rapidly. In the modern printed circuit board industry, product price has evolved into a core competitiveness for the survival of enterprises. Enterprises need to minimize manufacturing costs while ensuring customer quality requirements, so as to create more value, which is beneficial to enterprise development. Then lean production and cost saving will be what every enterprise must do. Since the raw material and labor costs of printed circuit boards are constantly increasing, it is necessary to continuously explore production processes that are conducive to cost reduction from process production....
