Problems solved by technology

[0002] At present, the existing production method of flexible circuit boards is to directly die-cut products, and test individual products one by one. Low, waste manpower and material resources, and it is difficult to completely detect unqualified finished products; for this reason, we have developed a method for quickly producing qualified flexible circuit boards that can judge whether the flexible circuit board is qualified by visual inspection

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] attached Figure 1-6 The method for rapidly producing a qualified flexible circuit board according to the present invention includes the following steps, taking the design requirement of tolerance 0.2mm as an example:

[0021] 1. Using the copper etching method, the circuits of a plurality of regularly arranged flexible circuit boards 4 and the process rings 2 distributed diagonally on the raw material plate 1 are copper-etched out on the original material plate 1; the process ring 2 includes concentric 1.4mm*1.8mm inner copper ring 6 and outer copper ring 8 with an inner diameter of 2.4mm;

[0022] 2. While punching the flexible circuit board 4, punch a round punch hole 5 in the inner ring of the 1.4mm*1.8mm inner copper ring 6, with an aperture of 1.0mm; Between the outer copper ring 8, punch a small hole 7 with a diameter ...

Abstract

The invention discloses a method for rapid production of qualified flexible circuit boards. The method includes the steps of using a copper corrosion method for copper etching of circuits of a plurality of regularly arranged flexible circuit boards on raw material boards and process rings including inner copper rings on the raw material boards; punching round punch holes in the inner rings of the inner copper rings while punching the flexible circuit boards to obtain the flexible circuit boards, waste material areas and round punch holes in the process rings in the waste material areas; visually checking whether the round punch holes in the waste material areas are tangential to the inner copper rings in the process rings. If yes, the punched flexible circuit boards are unqualified, otherwise the punched flexible circuit boards are qualified. The method can realize qualification detection by visually checking whether the round punch holes in the waste material area are tangential to the inner copper rings in the process rings. The method is simple and convenient, and improves production efficiency.

Description

technical field [0001] The invention relates to an improvement of a production method of a flexible circuit board, in particular to a method for rapidly producing a qualified flexible circuit board that can judge whether the flexible circuit board is qualified by visual inspection. Background technique [0002] At present, the existing production method of flexible circuit boards is to directly die-cut products, and test individual products one by one. Low, waste manpower and material resources, and it is difficult to completely detect unqualified finished products; for this reason, we have developed a method for quickly producing qualified flexible circuit boards that can judge whether the flexible circuit board is qualified by visual inspection. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a method for quickly producing qualified flexible circuit boards that can judge whether the flexi...
