Laser processing bearing device of flexible circuit board

Abstract

The invention relates to a bearing device for the laser processing of a flexible printed circuit, which comprises a first surface and a second surface. The first surface is provided with at least one first groove and at least one vacuum-absorbing positioning hole; the at least one vacuum-absorbing positioning hole passes through the first surface and the second surface. The second surface is provided with at least one second groove; the sum of the depth of the second groove and the depth of the first groove which is corresponding to the second groove is less than the thickness from the first surface to the second surface of the bearing device for the laser processing of the flexible printed circuit. The bearing device for the laser processing of the flexible circuit board ensures that the double-sided flexible circuit board can be levelly fixed on a laser processing device, and can effectively improve the precision of the laser cutting of the double-sided flexible circuit board and effectively prevent bad connection and breaking off between or damage to electronic components and the flexible circuit board.

Description

technical field [0001] The invention relates to a carrying device, in particular to a carrying device for laser processing of a flexible circuit board. Background technique [0002] With the continuous development of electronic products in the direction of miniaturization and diversified functions, flexible circuit boards, which have been widely used in various electronic products, are becoming smaller and smaller, and the circuit density is getting higher and higher. In order to save raw material costs and facilitate production, a plurality of identical or different line units are usually arranged on a flexible circuit board for joint processing and production. Therefore, after the flexible circuit board has completed circuit fabrication and mounted electronic components, subsequent laser cutting processing is usually required. During laser cutting, the flexible circuit board is light and thin, and the vacuum adsorption workbench of the laser cutting machine is used to dir...

Problems solved by technology

However, when the flexible circuit board adopts double-sided mounting, that is, when electronic components are mounted on the opposite two surfaces of the flexible circuit board, the opposite two surfaces of the double-sided mounted flexible circuit board will be damaged by electronic components. Due to the existence of unevenness, it cannot be well fixed on the vacuum adsorption table of the laser cutting machine, which affects the accuracy of laser cutting

In addition, directly contacting and fixing the double-sided mounted flexible circuit board with the surface of the workbench may damage the good connection between the electronic components and the flexible circuit board, and even cause the electronic components to be damaged and fall off due to stress concentration, thereby affecting The quality of the finished flexible circuit board
