Embodiment Construction

[0026] The present invention provides a method for processing the inner hypotenuse of a PCB board. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] see figure 1 , which is a flowchart of the method for processing the beveled edge of the PCB board of the present invention. Such as figure 1 As shown, the method includes the following steps;

[0028] S1. Draw a straight line at the position tangent to the hypotenuse in the PCB board and convert it into the program format of CNC machining for CNC machining. At the same time, select a number of asymmetric non-plated holes on the edge of the board as positioning holes for positioning;

[0029] S...

Abstract

The invention discloses a method for machining the inner bevel edge of a PCB. The method includes the following steps that first, the position tangent with the inner edge to be beveled of the PCB board is straightened to be converted into the format of a routing belt, and meanwhile a plurality of asymmetric non-electroplated holes are selected at the edge of the board as positioning holes to perform positioning; then, a plurality of routing cutters with the same length are selected to plane a machine; after a cutter for routing the bevel edge is selected, the inner bevel edge starts to be routed; the board routing depth is adjusted according the depth of the bevel edge till the bevel edge machining is completed. Compared with the prior art, the bevel edge in the board can be machined; meanwhile, the utilization ratio of boards is improved, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of PCB processing, in particular to a method for processing the inner hypotenuse of a PCB board. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, printed circuit board, is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. [0003] At present, the bevel edge of PCB is mainly processed at a certain angle by a special bevel edge machine. Due to the defects of the bevel edge equipment, the bevel edge in the unit cannot be completed. The beveled edge of this kind of board is mainly set on the edge of the plate directly by adjusting the position of the beveled edge to the process edge or without setting the process edge at the bevel edge. [0004] In ...
