Embodiment Construction

[0026] The technical solution of the present invention is further described in non-limiting detail below in conjunction with the preferred embodiments and the accompanying drawings.

[0027] like Figure 1 to Figure 5 As shown, this embodiment provides a high temperature resistant flexible flat cable and a processing technology. The flexible flat cable includes an upper PI adhesive film 1, a lower PI adhesive film 2, and a PI adhesive film 1, 2 attached between the upper and lower PI adhesive films. the flat conductor 3.

[0028] The flexible flat cable processing process specifically includes the following steps:

[0029] S1. Conductor calendering; press the circular section copper conductor into a flat copper conductor 3 of a specified specification by a calendering machine. The calender is known in the art and will not be repeated in the present invention.

[0030] S2. Punching the film; punching the PI film by the FFC molding machine, and punching out the square hole 21...

Abstract

The invention discloses a processing technique of a high-temperature-resistance flexible flat cable. The processing technique includes the following steps of S1, conductor calendaring; S2, adhesive film punching; S3, pre-pressing forming; S4, fixed-length cutting; S5, positioning hole punching; S6, reinforcing plate pasting; and S7, splitting. The flexible flat cable is made of high-temperature-resistance PI, so that the ultimate temperature resistance is greatly increased, and the temperature-resistance index is improved from original 150 DEG C per 30 seconds to 300 DEG C per 30 seconds; in the processing process, through two times of hot pressing, the characteristics of short bonding time, large contraction ratio and the like of an adhesive film in the high-temperature attaching processare overcome; the problem of non-fusion-welding of PI adhesive film attaching can be solved at the same time.

Description

technical field [0001] The invention relates to the technical field of data transmission cables, in particular to a high temperature resistant flexible flat cable and a processing technology. Background technique [0002] Flexible flat cable, or FFC, is a data cable that is made of PET insulating material and extremely thin tinned flat copper wire and pressed by a laminating machine. Bending ability, the number and spacing of wires can be selected arbitrarily, which is convenient for wiring. [0003] Existing flexible flat cables generally use PET film, and the use temperature of the product is between 80 degrees and 105 degrees, which limits the field of product application. The current design of the traditional C3 field can still meet the requirements, but the existing products used in special fields, such as aircraft and special equipment, cannot meet the needs. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a high temperature res...
