Abstract
The utility model discloses a flexible printed circuit board of a touch screen. The flexible printed circuit board comprises a flexible printed circuit board body and a covering film, wherein a golden finger is arranged at the end part of the flexible printed circuit board body; the covering film is stuck on the back surface of the flexible printed circuit board body; and the covered area of the covering film is partially overlapped with the area where the golden finger is positioned along the length direction of the flexible printed circuit board body. The flexible printed circuit board of the touch screen is not easily damaged in welding, and has strong resistance against high temperature.
Description
Technical field
The utility model relates to a kind of touch-screen flexible print circuit board.
Background technology
Touch-screen is assembled on the mainboard, need fix through scolding tin, adopts scolding tin welding FPC to advocate the mode of using pb-free solder at present, is beneficial to environmental protection.But the electric soldering iron temperature need reach more than 350 ℃ during pb-free solder, and this just causes FPC to be burnt out easily, and it is bad to come off etc. like copper sheet.Existing touch-screen flexible print circuit board is as depicted in figs. 1 and 2.
The utility model content
The utility model technical matters to be solved provides a kind of touch-screen flexible print circuit board, and this touch-screen flexible print circuit board can be not fragile when welding, and high-temperature resistance is strong.
The technical solution of utility model is following:
A kind of touch-screen flexible print circuit board comprises flexible print circuit board body and coverlay, and the end of flexible print circuit board body is provided with golden finger; Coverlay sticks on the back side of flexible print circuit board body, and the overlay area of coverlay and golden finger region are overlapping on the length direction top along the flexible print circuit board body.
The overlay area of coverlay and golden finger region overlap the zone length be 0.5mm.
Front at the flexible print circuit board body also is pasted with coverlay.
Beneficial effect:
The touch-screen flexible print circuit board of the utility model; Because the pro and con of flexible print circuit board body is provided with resistant to elevated temperatures coverlay, can prevent that the flexible print circuit board body from being burnt out when welding, in addition; The back side at the flexible print circuit board body; Overlap in the overlay area of coverlay and golden finger region, so the good copper sheet of protective money finger can when welding, not come off (because the edge weak link that golden finger is windowed is the easiest in high temperature deformation).

Fig. 2 is the structure synoptic diagram of existing touch-screen flexible print circuit board;
Fig. 3 is the Facad structure synoptic diagram of the touch-screen flexible print circuit board of the utility model;
Fig. 4 is the structure synoptic diagram of the touch-screen flexible print circuit board of the utility model;
Label declaration: 1-flexible print circuit board body, 2-back side coverlay, 3-front coverlay, 4-golden finger.
Embodiment
Below will combine accompanying drawing and specific embodiment that the utility model is explained further details:
Embodiment 1:
A kind of touch-screen flexible print circuit board comprises flexible print circuit board body and coverlay, and the end of flexible print circuit board body is provided with golden finger; Coverlay sticks on the back side of flexible print circuit board body, and the overlay area of coverlay and golden finger region are overlapping on the length direction top along the flexible print circuit board body.
The overlap length in zone of the overlay area of coverlay and golden finger region is 0.5mm (described length is the size along the length direction of flexible print circuit board body).
Front at the flexible print circuit board body also is pasted with coverlay.
Shown in Fig. 3-4, increase the flexible print circuit board body back side golden finger length of windowing, paste the resistant to elevated temperatures coverlay of one deck more in the above.As, originally the golden finger length of windowing is 2.4mm, and the length of windowing is now made 2.9mm, and the 0.5mm that opens uses coverlay to touch more, and the length of the final use of golden finger remains 2.4mm like this.
Claims (3)
1. a touch-screen flexible print circuit board is characterized in that, comprises flexible print circuit board body and coverlay, and the end of flexible print circuit board body is provided with golden finger; Coverlay sticks on the back side of flexible print circuit board body, and the overlay area of coverlay and golden finger region are overlapping on the length direction top along the flexible print circuit board body.
2. touch-screen flexible print circuit board according to claim 1 is characterized in that, the overlay area of coverlay and golden finger region overlap the zone length be 0.5mm.
