Abstract
The utility model relates to an anti-tear flexible printed circuit board. The anti-tear flexible printed circuit board comprises a circuit board main body and a connector, wherein the connector is connected with the circuit board main body through a connection area; a tear opening of the connection area has an arc-shaped structure; and a reinforced copper sheet is arranged inside the arc-shaped structure. According to the utility model, the tear opening which tears normally has the arc-shaped structure, and simultaneously the reinforced copper sheet is added, so that the stress at the tear opening can be reduced, and the anti-tear effect can be improved; and therefore, the flexibility of the flexible printed circuit board is enhanced, and the product quality is improved.
Description
Technical field
The utility model relates to a kind of circuit board structure, is specifically related to a kind of anti-flexible print circuit board of tearing.
Background technology
Flexible print circuit board is a kind ofly to have a height reliability with what polyimides or polyester film were that base material is processed, and excellent pliability printed substrate has that distribution density is high, in light weight, the characteristics of thin thickness, can be used in the multiple electronic product.Existing flexible print circuit board is torn phenomenon because of external force causes unavoidably, thereby is caused scrapping of product in production or use, lets alone to come into the market if can not in time find, certainly will cause certain potential safety hazard.
The utility model content
To the deficiency of prior art, the utility model provides a kind of anti-flexible print circuit board of tearing effect, strengthening product strength that promotes.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
Prevent tearing flexible print circuit board, it comprises wiring board main body and the connector that is connected through a bonding pad with said wiring board main body, and the tearing notch of said bonding pad is an arc-shaped structure, is provided with one in the inboard of said arc-shaped structure and reinforces copper sheet.
Preferably, the position of said tearing notch is the junction of bonding pad and wiring board main body or the junction of bonding pad and connector.
Preferably, the shape of said reinforcing copper sheet and arc-shaped structure are complementary.
The anti-flexible print circuit board of tearing that the utility model is set forth; Compared with prior art, its beneficial effect is: the utility model is designed to arc-shaped structure with the tearing notch that regular meeting tears, and sets up the reinforcing copper sheet simultaneously; Can reduce port tearing position stress; Promote tear-resistant effect, thereby strengthen the flexility of flexible print circuit board, improved the quality of product.
Description of drawings
Accompanying drawing 1 is the anti-structural representation of tearing flexible print circuit board of the utility model.
Embodiment
Below, in conjunction with accompanying drawing and embodiment, the utility model anti-torn flexible print circuit board do and further describe, so that clearerly understand the utility model technological thought required for protection.
As shown in Figure 1, to prevent tearing flexible print circuit board, it comprises wiring board main body 1; And the connector 2 that is connected through a bonding pad 3 with wiring board main body 1; The tearing notch 4 of bonding pad 3 is designed to arc-shaped structure, and the tearing notch 4 of this arc-shaped structure can reduce its suffered stress, thereby strengthens tear-resistant effect; In order further to promote the tear-resistant effect of flexible print circuit board; Being provided with one in the inboard of the tearing notch 4 of arc-shaped structure and reinforcing copper sheet 5, can certainly be that other kinds reinforcement material is made, and reinforces the shape of copper sheet 5 and the tearing notch 4 of arc-shaped structure and is complementary.
Tearing notch 4 is meant in the FPC and is prone to the place of tearing because of the external force effect that in the utility model preferred embodiment, its position be bonding pad 3 and the junction of wiring board main body 1 or the junction of bonding pad 3 and connector 2.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection range of the utility model claim all according to the technical scheme and the design of above description.
Claims (3)
