Description
Technical field
It the utility model is related to copper foil manufacture field, and in particular to a kind of complex copper paillon foil.
Background technology
With the development of science and technology, in some electronic equipments, the requirement of the densification of printed circuit board (PCB) gradually increases, right
Used copper foil must be improved to form precision circuit.When making fine-line, influence product yield it is main because
Element is thickness, surface state and cleannes of copper foil etc..In order to improve the high accuracy of outer-layer circuit pattern transfer, need to adopt in theory
With thinner copper foil, otherwise can influence the resolving power of following process, it will occur short circuit, insulation spacing deficiency, the super tolerance of line width,
Conductor easily floats.However, under the prior art, had difficulties in actual applications using relatively thin copper foil.
Current most common way is to use thicker copper foil at the beginning, then takes method for chemially etching, waits pressing work
After sequence is completed, copper foil is thinned using chemical corrosion method, then the process such as extra increase washing, dry, so as to realize copper foil
The purpose of thinning.Although above way can be such that copper foil is more thinned, problems be present.
1st, processing link is added, adds additional medicine, device, water power, manpower, time etc., cost is added, makes system
The manufacturing cycle of product is elongated.
2nd, the processing cost of waste water, waste liquid is added, adds environmental pressure, the main flow with advocating clean manufacturing now becomes
Gesture is disagreed.
3rd, by then passing through chemical method by originally thicker copper foil corrosion into relatively thin copper foil, copper resource is wasted, is increased
Cost is added.
4th, the homogeneity of copper thickness is difficult to ensure that, the quality of circuit is difficult to ensure that.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of complex copper paillon foil, it is not necessary to and chemical liquids remove, and
And can minimizes thinness, and and can solves the deficiency in background technology.
The utility model is achieved through the following technical solutions：A kind of complex copper paillon foil, including a support slice with
And the copper foil on support slice is positioned over, the both ends of the copper foil are compressed by two movable blocks, and are consolidated by two movable blocks
Due to the upper surface of support slice.
As preferable technical scheme, the movable block includes adhesive portion and compressed part, and adhesive portion medial extremity is set
A magnetic adsorption plate is equipped with, the compressed part is arranged at the top of support slice, and compresses the copper foil both ends of centre.
As preferable technical scheme, the movable block is integrally L-shaped.
As preferable technical scheme, the upper surface of the compressed part is less than the upper surface of copper foil.
As preferable technical scheme, the support slice is one piece of sheet metal, and it is used can be by the gold of magnet adsorption
Belong to iron plate, movable block is mutually attracted with support slice by magnetic force.
As preferable technical scheme, the contact jaw of the compressed part and copper foil sets a rubber bearing.
The beneficial effects of the utility model are：The utility model is simple in construction, can preferably protect copper foil so that copper
The thinness of paillon foil makes maximum, can effectively realize the transport of copper foil, and safety when ensureing pressing, and convenient disassembly,
Without using any chemical liquids.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
This specification（Including any accessory claim, summary and accompanying drawing）Disclosed in any feature, except non-specifically chatting
State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As shown in figure 1, including a support slice 5 and the copper foil 3 being positioned on support slice 5, the both ends of copper foil 3
Compressed by two movable blocks, and be fixed on by two movable blocks the upper surface of support slice 5, movable block 5 include adhesive portion 1 and
Compressed part 4, the medial extremity of adhesive portion 1 are provided with a magnetic adsorption plate, and compressed part is arranged at the top of support slice, and compress the copper of centre
The both ends of paillon foil 3.
Wherein, movable block 5 is overall L-shaped, wherein, support slice is one piece of sheet metal, and it, which is used, to be inhaled by magnet
Attached metal iron plate, movable block are mutually attracted with support slice by magnetic force.Such structure can pass through adhesive portion and support
Thin slice adhesive, and movable block is then securable to the both sides of support slice, and the compressed part at top can compress the both ends of copper foil,
Prevent copper foil from dropping.
Copper foil 3 needs to press with prepreg, therefore the upper surface of compressed part is less than the upper surface of copper foil, so i.e.
Can portion influence copper foil normal fitting.
In addition, damaging the side of copper foil during in order to prevent that compressed part from contacting with copper foil by pressure, spy is in compressed part and copper foil
Contact jaw one rubber bearing 2 is set, after the completion of pressing, as long as we remove movable block and support slice, you can real
The quick dismounting of existing copper foil.
The beneficial effects of the utility model are：The utility model is simple in construction, can preferably protect copper foil so that copper
The thinness of paillon foil makes maximum, can effectively realize the transport of copper foil, and safety when ensureing pressing, and convenient disassembly,
Without using any chemical liquids.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work, should all cover within the scope of protection of the utility model.
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
