Abstract
The invention discloses a preparation method of adhesive tapes provided with hand-tore release paper strips. Each adhesive tape comprises a pressure-sensitive adhesive, and original release paper and auxiliary release paper covering the two sides of the pressure-sensitive adhesive respectively. The preparation method comprises following steps: cutting; drilling; first punching; adhesive removing; second punching; waste material removing; and sticking of adhesive tapes. Beneficial effects are that: the preparation method is capable of solving preparation problems of adhesive tapes provided with hand-tore release paper strips in moulding zones, increasing utilization ratio of the adhesive tapes, and reducing processing cost on adhesive tape waste material in the field of environmental protection.
Description
Technical field
The present invention relates to a kind of making method of adhesive tape, particularly a kind of adhesive tape making method with hand tear tape separate-type paper that can improve adhesive tape utilization ratio.
Background technology
Flexibility printed circuit board (FPC) so that it is light, thin, volume is little, deflection, can three-dimensional wiring form as a fastest-rising kind in printed wiring industry.Develop rapidly along with electronics, electronic industry, more and more require plant and instrument miniaturization, lightweight, high reliability and simplification assembling process, under some special conditionss, traditional hard printed circuit board has been not suitable for using, and what need use is the flexibility printed circuit board (FPC) with excellent properties.Flexibility printed circuit board (FPC) base material is to be formed with jelly is bonding by insulating plastics film and Copper Foil.When being mounted on equipment, realizes by adhesive tape sticking flexibility printed circuit board (FPC).At present industry is made the adhesive tape that leaves paper with hand tear tape now, is to adopt first tape sticker on plank, with mould, hand tear tape separate-type paper place waste material is washed out, then the separate-type paper more renewing, then go out desired external form.The shortcoming of this making method is cannot complete shaping area with the making of the interior adhesive tape with hand tear tape separate-type paper.
Traditional adhesive tape technique with hand tear tape separate-type paper is sawing sheet → boring → die-cut (adhesive tape shape) → laminating → die-cut (hand tear tape waste material is die-cut) → replacing separate-type paper → punch extermal form, hand tear tape separate-type paper is exceeded to the border of flexibility printed circuit board (FPC) in punch extermal form operation, also that hand tear tape separate-type paper shape is out die-cut together in the time of punch extermal form.
Summary of the invention
Goal of the invention: the object of this invention is to provide a kind of can realization while needing to have hand tear tape adhesive tape in shaping area, can be by die-cut formation the adhesive tape making method with hand tear tape separate-type paper.
Technical scheme: a kind of adhesive tape making method with hand tear tape separate-type paper, adhesive tape comprises pressure sensitive adhesive and overlays on respectively the original-pack separate-type paper on pressure sensitive adhesive two sides, auxiliary separate-type paper;
Making method comprises the following steps:
A) sawing sheet: entire volume rubber belt material is split into needed size;
B) boring: get out the required mould pilot hole of mould on adhesive tape;
C) die-cut for the first time: hand tear tape place pressure sensitive adhesive is thrust together with auxiliary separate-type paper, but original-pack separate-type paper not to thrust;
D) except glue: just hand tear tape place pressure sensitive adhesive is removed together with auxiliary separate-type paper;
E) die-cut for the second time: according to the die-cut adhesive tape of final physical dimension of flexibility printed circuit board, the adhesive tape that overturns when die-cut, die-cut from original-pack separate-type paper one side, but auxiliary separate-type paper does not thrust;
F) remove waste material: the waste material of removing die-cut formation for the second time;
G) tape: the pressure sensitive adhesive with hand tear tape is attached on flexibility printed circuit board.
Preferred term, when described step e is die-cut for the second time, the auxiliary separate-type paper of incision.
Preferred term, when described step e is die-cut for the second time, the degree of depth of the auxiliary separate-type paper of incision is 0.08mm.
Beneficial effect: the present invention can solve shaping area has the adhesive tape of hand tear tape to make problem with interior; Improve the utilization ratio of adhesive tape; Reduce environmental protection to adhesive tape waste disposal expense.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, adhesive tape comprises pressure sensitive adhesive 1 and overlays on respectively the original-pack separate-type paper 2 on pressure sensitive adhesive 1 two sides, auxiliary separate-type paper 3;
Making method comprises the following steps:
A) sawing sheet: entire volume rubber belt material is split into needed size;
B) boring: get out the required mould pilot hole of mould 4(as shown in Figure 2 on adhesive tape);
C) die-cut for the first time: hand tear tape place pressure sensitive adhesive 1 is thrust together with auxiliary separate-type paper 3, but original-pack separate-type paper 2 not to thrust (as shown in Figure 3);
D) except glue: just hand tear tape place pressure sensitive adhesive 1 is removed (as shown in Figures 4 and 5) together with auxiliary separate-type paper 3;
E) die-cut for the second time: according to the die-cut adhesive tape of final physical dimension of flexibility printed circuit board, the adhesive tape that overturns when die-cut, die-cut from original-pack separate-type paper 2 one sides, but auxiliary separate-type paper 3 does not thrust (as shown in Figures 6 and 7);
F) remove waste material: the waste material of removing die-cut formation for the second time;
G) tape: the pressure sensitive adhesive with hand tear tape 1 is attached on flexibility printed circuit board.
When described step e is die-cut for the second time, incision auxiliary separate-type paper 3 degree of depth in the place's of removing photoresist are 0.08mm.
