Abstract
The utility model discloses a back-adhesive reinforcing board of flexible circuit board, the back-adhesive reinforcing board is adhibitted to the back of the flexible circuit board to reinforce the strength of the flexible circuit board, characterized in that: an adhesive layer is adhibitted to the link surface of the reinforcing board, a tearing layer is adhibitted to the adhesive surface of the adhesive layer. Usefully effects of this technical program are: because the adhesive layer is adhibitted to the link surface of the reinforcing board, and the tearing layer is adhibitted to the adhesive surface of the adhesive layer, in the assembly, when we tear the tearing layer off and adhibit the adhesive layer on the back of the flexible circuit board, the reinforcing board can be adhibitted to the flexible circuit board, with convenient and fast adhesion, and good adhibitting strength.
Description
Technical field
The utility model relates to a kind of stiffener, especially relates to a kind of gum stiffener of flexible PCB.
Background technology
Flexible PCB (FPC circuit board) in use generally needs a bonding overleaf metal reinforcing plates to strengthen the flexible PCB strength and stiffness.Bonding assembling process between flexible PCB and the metal reinforcing plates comprises: 1, and glue is to form adhesive linkage on the cloth of the flexible PCB back side; 2, stiffener is adhered to the bonding plane of adhesive linkage.This bonding assembling process trouble is time-consuming; Because fluid glue on the direct cloth in the flexible PCB back side, glue are crossed and flow to the non-bonding location of flexible PCB at most and shorten flexible PCB useful life easily, glue crosses at least that the adhesive strength difference comes off easily, and adhesive effect is poor.
The utility model content
The utility model provides a kind of gum stiffener of flexible PCB, and it has overcome, and the existing trouble of bonding assembling between existing flexible PCB and the stiffener is time-consuming, the deficiency of adhesive effect difference.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of gum stiffener of flexible PCB, this stiffener is adhered to the flexible PCB back side to strengthen flexible PCB intensity, it is characterized in that: be bonded with adhesive linkage on the joint face of this stiffener, bonding tearable absciss layer on the bonding plane of this adhesive linkage.
Described adhesive linkage is a double-sided adhesive layers.
Described stiffener, adhesive linkage and tearable absciss layer coincide relatively and mate.
The beneficial effect of the technical program is: owing to be bonded with adhesive linkage on the joint face of this stiffener, bonding tearable absciss layer on the bonding plane of this adhesive linkage, therefore as long as tearing off tearable absciss layer when assembling is adhered to bonding plane the flexible PCB back side then and stiffener can be adhered to flexible PCB, bonding convenience is quick, and adhesive strength is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the generalized section of the gum stiffener of flexible PCB.
Label declaration: stiffener 1, adhesive linkage 2, tearable absciss layer 3.
Embodiment
A kind of gum stiffener of flexible PCB, as shown in Figure 1, this stiffener is adhered to the flexible PCB back side to strengthen flexible PCB intensity, is bonded with adhesive linkage 2 on the joint face of this stiffener 1, bonding tearable absciss layer 3 on the bonding plane of this adhesive linkage 2.This stiffener 1, adhesive linkage 2 and tearable absciss layer 3 coincide relatively and mate.Then bonding plane is adhered to the flexible PCB back side and stiffener 1 can be adhered to flexible PCB as long as tear off tearable absciss layer 3 during assembling, bonding convenience is quick, and adhesive strength is good.
Specifically describe the processing method of this gum stiffener down below: elder generation is two-sided tape on bulk metal plate joint face is directly bonding, and the adhesive linkage of two-sided tape is the adhesive linkage of present embodiment, and the tearable absciss layer of two-sided tape also is the tearable absciss layer of present embodiment; Punch out needed gum stiffener according to flexible PCB back side shape more at last, the metallic plate that has adhesive linkage, tearable absciss layer that this punches out both had been the gum metallic plate.This metallic plate can be corrosion resistant plate, copper coin etc.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
Claims (3)
1. the gum stiffener of a flexible PCB, this stiffener are adhered to the flexible PCB back side to strengthen flexible PCB intensity, it is characterized in that: be bonded with adhesive linkage on the joint face of this stiffener, bonding tearable absciss layer on the bonding plane of this adhesive linkage.
2. the gum stiffener of a kind of flexible PCB according to claim 1, it is characterized in that: described adhesive linkage is a double-sided adhesive layers.
