Abstract
The utility model is related to a kind of double faced adhesive tape for flexible PCB, which includes release film, the double faced adhesive tape being arranged on release film and the handle film being arranged on double faced adhesive tape, offered on the handle film for link up with across lifting opening.Compared with prior art, the utility model by opened up on handle film for link up with across lifting opening, useless mode is gone into the lifting that traditional manual tweezers go useless mode and automatic film drawing machine suction nozzle that useless mode is gone to replace with hook, not only increase handle film goes useless efficiency, and go useless success rate high, the normal use of flexible PCB has been effectively ensured；Both manually handle film can be lifted with hook, and also can was hook by the suction nozzle replacing of automatic film drawing machine, is lifted handle film by the hook of automatic film drawing machine, flexibility is good.
Description
Technical field
The utility model belongs to double faced adhesive tape technical field, is related to a kind of double faced adhesive tape for flexible PCB.
Background technology
Continuous universal with smart mobile phone, requirement of the consumer for handset is higher and higher, in addition to aesthetics it
Outside, also require handset that there is smaller thickness.Since fuselage is more and more thinner, each unit workpiece of interior of mobile phone is accordingly also got over
Next smaller, flexible PCB (FPC) also becomes smaller, and then it is two-sided to make flexible PCB being sticked together with fuselage interior
The size of glue also constantly becomes smaller.The existing double faced adhesive tape for flexible PCB includes counterdie and the band that is fitted on counterdie
The double faced adhesive tape of handle in use, the double faced adhesive tape with handle is torn off from counterdie, and is put into localization tool, later again will be soft
Property circuit board workpiece be placed in localization tool and fit with double faced adhesive tape, carry out pressurize after, you can by wherein the one of double faced adhesive tape
Face is sticked on workpiece, later again tears off handle from double faced adhesive tape, and workpiece can be attached to the corresponding position in mobile phone inner casing.
Since the size of handle is very small, there are mainly two types of the methods at present tearing off handle from double faced adhesive tape：
1) it using manually going useless mode, is torn handle by finger and the cooperation for taking the photograph son, but this mode is less efficient；
2) useless mode is gone using automatic film drawing machine, handle is drawn using the suction nozzle of automatic film drawing machine, by handle from double faced adhesive tape
On tear off, but this mode success rate is relatively low, goes useless rate to be only capable of reaching 80% or so, can not accomplish to go to give up completely.
Therefore, the process of going to give up of handle has seriously affected the production efficiency of mobile phone.
Utility model content
The purpose of this utility model is exactly to be provided a kind of for flexibility to overcome the problems of the above-mentioned prior art
The double faced adhesive tape of circuit board.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of double faced adhesive tape for flexible PCB, which includes release film, it is double to be arranged on release film
Face glue and the handle film being arranged on double faced adhesive tape, offer on the handle film for link up with across lifting opening.When needing hand
When handle film tears off from double faced adhesive tape, using a hook across lifting opening, it is lifted up later, you can handle film is quick
It tears.
Further, the handle film includes the handle film sticking part to fit with double faced adhesive tape and is bonded with handle film
The connected handle film pulling part in portion, the lifting opening are opened on handle film pulling part.Handle film sticking part is protected with double faced adhesive tape
Good fit is held, does not influence the adhesive of double faced adhesive tape, handle film pulling part is not contacted with double faced adhesive tape, by linking up with carrying handle film
Pulling part, you can all take entire handle film from double faced adhesive tape off.
Further, the length of the handle film pulling part is 6.5-7.5mm, width 6-7mm.Existing flexible electrical
The size of road plate is smaller, and the size of matched double faced adhesive tape is also smaller so that the size of the handle area of double faced adhesive tape is general
For 7mm × 6.44mm, it is difficult to remove handle from double faced adhesive tape.The utility model leads under the premise of not increasing grip size
It crosses and opens up lifting opening on handle film, take handle film off convenient for passing through hook.
Further, the length of the handle film pulling part is 7mm, width 6.44mm.
Further, the lifting opening is rounded, C fonts, cross or rice font.Above-mentioned several lifting opening types are equal
It can realize that the lifting of handle film goes to give up.
Further, the hook is arranged on automatic film drawing machine.It is hook by the suction nozzle replacing of automatic film drawing machine, it will
Originally suction nozzle becomes linking up with after lifting opening to the pull lift action of handle film to the sucking action of handle, is greatly improved handle
Film goes useless efficiency and success rate.
The utility model in practical application, double faced adhesive tape is torn off from release film using handle film, and make double faced adhesive tape with
Flexible PCB fits；It will link up with across lifting opening, be lifted up later, you can by handle film torn fast, realize handle
The quick separating of film and double faced adhesive tape.
Compared with prior art, the utility model has the characteristics that：
1) by opened up on handle film for link up with across lifting opening, traditional manual tweezers are gone into useless mode and automatic
Useless mode is gone in the lifting that film balance suction nozzle goes useless mode to replace with hook, and not only increase handle film goes useless efficiency, and goes to give up
Success rate is high, and the normal use of flexible PCB has been effectively ensured；
2) both manually handle film can be lifted with hook, also can is hook by the suction nozzle replacing of automatic film drawing machine, by certainly
The hook of dynamic film balance lifts handle film, and flexibility is good.
