Problems solved by technology

[0002] With the development trend of intelligent manufacturing, the production information of products needs to be included in the system database management and control. There are many production processes of flexible circuit boards (FPC), which especially need to be included in the system database management and control such as MES. However, if the FPC has a black cover film, Because the black cover film is black, after it is pasted on the FPC, it will also cover the QR code area used for traceability on the edge of the FPC board, and the QR code cannot be recognized and read, resulting in th

Embodiment Construction

[0023] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0024] like Figure 1 to Figure 5 As shown, the present invention provides a method for traceability of the whole process of FPC with a black cover film, and its technological process is as follows:

[0025] Step 1: The black cover film 2 opens a window in the area corresponding to the two-dimensional code 11 of the FPC board 1 to make a two-dimensional code window 22, such as figure 2 shown;

[0026] Step 2: The black cover film 2 is pre-laminated on the FPC board 1 that has been laser-drilled with a two-dimensional code 11 on the edge of the board, such as image 3 shown;

[0027] Step 3: The black cover film 2 is thermocompressed on the FPC board 1;

[0028] Step 4: The light-transmitting cover film 3 is pre-laminated on the two-dimensional code window 22 on the edge of the FPC board 1;

[0029] Step 5...

Abstract

The invention discloses a full-process tracing method for an FPC with a black cover film, comprising the following steps: S1, a two-dimensional code window is formed by windowing in an area, corresponding to a two-dimensional code of an FPC board, of a black cover film; S2, the black cover film is pre-attached to the FPC board with a two-dimensional code formed in the edge by laser drilling; S3, the black cover film is thermally pressed on the FPC board; S4, a light-transmitting cover film is pre-attached to a two-dimensional code window in the edge of the FPC board; S5, the light-transmittingcover film is thermally pressed on the two-dimensional code window in the edge of the FPC board; and S6, the black cover film and the light-transmitting cover film are baked and cured on the FPC board. Because the black cover film is windowed at the two-dimensional code window and the light-transmitting covering film is transparent, the two-dimensional code is in a recognizable protection state in all procedures after the black cover film is attached to the FPC board, and full-process tracing of an FPC with a black cover film is realized.

Description

technical field [0001] The invention relates to the field of manufacturing flexible circuit boards (FPC), in particular to a method for tracing the entire process of an FPC with a black cover film. Background technique [0002] With the development trend of intelligent manufacturing, the production information of products needs to be included in the system database management and control. There are many production processes of flexible circuit boards (FPC), which especially need to be included in the system database management and control such as MES. However, if there is a black cover film on the FPC, Because the black cover film is black, after it is pasted on the FPC, it will also cover the QR code area used for traceability on the edge of the FPC board, and the QR code cannot be recognized and read, resulting in the inability to associate the processes before and after the FPC black cover film is laminated Traceability, until the FPC with black cover film cannot realize ...
