Description
Technical field
The utility model is related to protective film field technology, refer in particular to it is a kind of can be by the scrap of mobile phone FPC flexible circuit boards
Glue the protective film walked.
Background technology
FPC is the English abbreviation of flexible PCB, is using polyimides or polyester film as a kind of tool made of base material
There are height reliability, excellent flexible printed circuit to have the characteristics that Distribution density is high, light-weight, thickness is thin.
By taking dual platen as an example, the processing procedure of dual platen is as follows：Sawing sheet → drilling → PTH → plating → pre-treatment → patch dry film
→ contraposition → exposure → development → graphic plating → demoulding → pre-treatment → patch dry film → contraposition exposure → development → etching → de-
Film → surface treatment → paste epiphragma → compacting → solidification → heavy nickel gold → lettering symbol → shearing → electrical measurement → punching → final inspection →
Packaging → shipment.
The processing procedure of single sided board is as follows：Sawing sheet → drilling → patch dry film → contraposition → exposure → development → etching → demoulding → table
Surface treatment → paste epiphragma → compacting → solidification → surface treatment → heavy nickel gold → lettering symbol → shearing → electrical measurement → punching → end
Inspection → packaging → shipment.
Either single sided board or dual platen, all manufacturing procedures before packing shipment are all more or less to FPC
Surface pollute, for example, shearing, punching process can FPC remained on surface scrap, traditional treatment method be using air draught or
The mode of blowing, scrap is drained, but this chip removal mode cleaning effect is bad, cause after shipment there are still fines can
Energy.
Utility model content
In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of FPC waste discharges
Protective film not only plays a protective role to FPC plates, and tear protective film when can be whole by all scrap on FPC plates
It glues, reaches waste discharge purpose, to overcome the deficiencies in the prior art.
To achieve the above object, the utility model is using following technical solution：
A kind of FPC waste discharges protective film, the FPC waste discharge protective films be multi-layer compound structure, including rubber rubberised layer, pet layer,
Receive ion parting agent layer, the rubber rubberised layer, pet layer, ion parting agent layer of receiving from top to bottom are cascading.
As a preferred embodiment, the thickness of the rubber rubberised layer is 110-160um.
As a preferred embodiment, the thickness of the pet layer is 200-250um.
As a preferred embodiment, the thickness for receiving ion parting agent layer is 30-60um.
The utility model has clear advantage and advantageous effect compared with prior art, specifically, by above-mentioned technology
Scheme it is found that the FPC waste discharge protective films have three layers structure altogether, including from top to bottom the rubber rubberised layer, pet layer of stacked arrangement,
Receive ion parting agent layer, wherein the rubber rubberised layer provides bonding force；The pet layer plays support in protective film production and processing
The effect of skeleton, the main body as protective film have effects that anti-scratch；This receive ion parting agent layer be based on sodium ion be sun
The effect of ion generates chemical reaction with two layers of diaphragm after coating, original rubber rubberised layer can be made more to soften, thus will
After full wafer protective film is pasted on FPC plates, tearing, all scrap remained on flexible circuit board simultaneously are glued by protective film, are reached
The purpose of waste discharge.
More clearly to illustrate the structure feature and effect of the utility model, come below in conjunction with the accompanying drawings with specific embodiment pair
The utility model is described in detail.
Description of the drawings
Fig. 1 is the sectional view of the embodiment of the utility model.
Description of drawing identification：
10, rubber rubberised layer 20, pet layer
30, ion parting agent layer is received.
Specific implementation mode
It please refers to shown in Fig. 1, that show the concrete structures of the preferred embodiment of the utility model, are a kind of FPC rows
Useless protective film, is rolled into tubular after molding, when use, tubular protective film was unfolded, and cuts out and adheres to again on FPC flexible circuit boards, on the one hand
Play a protective role to flexible circuit board process, on the other hand tear protective film while can will remain on flexible circuit board
Scrap glue.
The FPC waste discharges protective film is multi-layer compound structure, including rubber rubberised layer 10, pet layer 20, ion mould release of receiving
Layer 30, the rubber rubberised layer 10, pet layer 20, ion parting agent layer 30 of receiving from top to bottom are cascading.
Wherein, the thickness of the rubber rubberised layer 10 is 110-160um.The rubber rubberised layer 10 has softness, elasticity
Well, the resistance to characteristic being hit with vibration, durability is good, with excellent light resistance, ozone resistants, resistance to weathering,
Anti-flammability etc., adhesive strength hardly declines after making protective film many decades indoors bonding with FPC plates.
The thickness of the pet layer 20 is 200-250um.The pet layer 20 can be hyaline layer, or coloured thin
Film, with certain hardness, the skeleton function supported in being produced and processed as protective film, the main body as protective film has anti-
The effect of scratching.
The thickness for receiving ion parting agent layer 30 is 30-60um.It is received before ion parting agent layer 30 uncoated, merely
There is very strong bonding force by the diaphragm that rubber rubberised layer 10 and pet layer 20 form, paste and need to tear energetically on product
It can tear, and be easy to be adhesive in product surface after tearing, be only applicable to disposably paste the package packing supplies used, such as
The sealing tape of common courier packages' case can be packed with this two layers of diaphragm.The present embodiment is in two layers traditional of diaphragm
（That is rubber rubberised layer 10 and pet layer 20）On the basis of increase sodium ion release layer, based on sodium ion be cation effect,
Chemical reaction is generated with two layers of diaphragm after coating, original rubber rubberised layer 10 can be made more to soften, bonding force is cut
It is weak, but be unlikely to be reduced to and do not have viscous force, and full wafer protective film becomes soft and possesses elastic force, it, can be with after being pasted on FPC plates
When reaching and cling purpose, and tearing, it is only necessary to soft power can easily tear protective film full wafer, therefore, Ci Zhongbao
All scrap remained on flexible circuit board can be glued, glue process tearing due to protective film by cuticula while tearing
It opens than milder, the scrap being sticked on protective film will not be made to fall to again on FPC plates.
In conclusion the design focal point of the utility model is, which haves three layers altogether structure, including by
Up to the rubber rubberised layer 10 of lower stacked arrangement, pet layer 20, ion parting agent layer 30 of receiving, wherein the rubber rubberised layer 10 provides
Bonding force；The pet layer 20 plays the role of support frame in protective film production and processing, and the main body as protective film has anti-
The effect of scratching；This receive ion parting agent layer 30 based on sodium ion be cation effect, after coating with two layers of diaphragm generationization
Reaction is learned, original rubber rubberised layer 10 can be made more to soften, after full wafer protective film is pasted on FPC plates, is being torn
All scrap remained on flexible circuit board are glued by protective film simultaneously, achieve the purpose that waste discharge.
The above descriptions are merely preferred embodiments of the present invention, not makees to the technical scope of the utility model
Any restrictions, therefore any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent change
Change and modify, is still within the scope of the technical solutions of the present invention.
