automatic expansion and contraction method for a PCB circuit and drill holes

Abstract

The invention provides a PCB (Printed Circuit Board) line and road drilling automatic expansion and contraction method, which comprises the following steps of: reading a line layer and a drilling layer in a PCB file lamination layer; Displaying the name, the expansion and contraction coefficient and the check box of each layer of the circuit layer in a row in a window, filling each row of data bya user, and selecting the expansion and contraction by the check box after check; filling Program inspection parameters; executing Expansion and contraction, ynamically filling an expansion and contraction instruction in the engineering manufacturing software into the engineering manufacturing software through a program, the engineering manufacturing software receives the instruction to execute expansion and contraction, displaying all expansion and contraction layer in a centralized mode, filling the parameters in a centralized mode, and preventing error expansion and contraction caused by too many layers; And performing automatic filling of the drilling parameters: combining the obtained line expansion and shrinkage parameters with the drilling data, automatically analyzing and calculating the expansion and shrinkage data of the drilling layer, and automatically filling the drilling expansion and shrinkage parameters.

Description

technical field [0001] The invention relates to a PCB manufacturing method, in particular to a method for automatic expansion and contraction of PCB circuit and drilling holes. Background technique [0002] With the rapid development of high-layer circuit boards, the orders of PCB processing factories also tend to develop in the direction of high-layer orders. The expansion and contraction parameters of high-layer and buried blind holes are very complicated, and it is difficult to remember a large number of expansion and contraction data. , the expansion and contraction levels of the line layer and the drilling layer reach more than a dozen to dozens of layers, and manual input of the expansion and contraction coefficients is required layer by layer for manual expansion and contraction. Such a large number of cumbersome operations are not only prone to misinput parameters, operational errors, Moreover, it is time-consuming, so the existing methods can no longer meet the need...

[0002] With the rapid development of high-layer circuit boards, the orders of PCB processing factories also tend to develop in the direction of high-layer orders. The line expansion and contraction parameters of high-layer and buried blind holes are very complicated, and it is difficult to remember a large number of expansion and contraction data. , the expansion and contraction levels of the line layer and the drilling layer reach more than ten to dozens of layers, and manual expansion and contraction are required to be manually input layer by layer. Such a large number of cumbersome operations are not only prone to misinput parameters, operational errors And it is time-consuming, so the existing methods can no longer meet the needs of efficient and fast PCB engineering production.
