Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] see Figure 1-2 , the present invention provides a technical solution: a Z-shaped slot hole processing method, specifically comprising the following steps:

[0026] S1. Cutting: use a fully automatic cutting machine to cut the FR4 board, and cut the FR4 board into the designed size;

[0027] S2. Drilling: Use a drilling machine to drill the cut FR4 board. When drilling, first process 1 red stacked hole area, the processing sequence is from left to righ...

Abstract

The invention discloses a Z-shaped slotted hole machining method which specifically comprises the following steps that S1, cutting is carried out by cutting an FR4 board by using a full-automatic cutting machine, and cutting the FR4 board into the designed size; and S2, drilling is conducted, specifically, a drilling machine is used for drilling the cut FR4 board, during drilling, a red hole stacking area is machined firstly, the machining sequence is from left to right, then a green area 2 is machined to remove burr holes, then a blue hole stacking area 3 is machined, and the machining sequence is from left to right. According to the Z-shaped slotted hole machining method, the drill point rotates in the forward direction during drilling, and drilling needs to be carried out from a hangingposition to an entity position; according to mechanical stress analysis, burrs can be prevented from being formed at edge difference sets of stacked holes, so that the quality yield of products is greatly improved, the problem of manual burr repairing is avoided, the production efficiency of the products is improved, and the production cost of the products is greatly reduced finally.

Description

technical field [0001] The invention relates to the technical field of slot hole processing, in particular to a Z-shaped slot hole processing method. Background technique [0002] Printed circuit boards, also known as printed circuit boards, are providers of electrical connections for electronic components. Printed circuit boards are often represented by "PCB" instead of "PCB boards". Its development has a history of more than 100 years. Its design is mainly layout design; the main advantage of using circuit boards is to greatly reduce wiring and assembly errors, improve the automation level and production labor rate, and can be divided into single-panel, double-panel, and four-layer according to the number of layers of circuit boards. Boards, six-layer boards and other multi-layer circuit boards, because printed circuit boards are not general end products, so the definition of names is slightly confusing, for example: motherboards for personal computers are called motherboa...
