Abstract
This utility model provides a kind of aluminium foil mould release membrance, is to arrange one layer of silicone oil on aluminium foil, and described silicone oil is release silicone oil, and the thickness of silicon layer is 1～3 micron.The aluminium foil mould release membrance that the utility model proposes, because aluminium foil has preferable release effect after being coated with silicone oil, therefore has the thermostability of brilliance, higher resistance to compression, plays the technique effect same with Copper Foil, and greatly reduce cost in substrate pressing.
Description
Technical field
This utility model belongs to microelectronic element production field, is specifically related to a kind of film for flexible PCB pressing technique.
Background technology
Flexible PCB is called for short soft board (also known as FPC), lightweight, thickness is little, can effectively save small product size, apply more and more extensive in communicating terminal industry.In flexible PCB production process, its process for pressing stage the most generally uses Copper Foil pressing, laminating layer and inner plating between Copper Foil, and wherein film and inner plating are materials to be laminated；Additional steel plates, removes Copper Foil, steel plate, i.e. obtains required circuitous pattern after heating and pressing.
Because Copper Foil has the defect of price, complex manufacturing, this area needs to develop cheap, and is resistant to the succedaneum of the Copper Foil of hot conditions in process for pressing.
Utility model content
For solving the deficiency that prior art exists, the purpose of this utility model is to propose a kind of to open film for flexible PCB pressing technique.
For realizing this utility model purpose technical scheme it is:
A kind of aluminium foil mould release membrance, is to arrange one layer of silicone oil on aluminium foil, and described silicone oil is release silicone oil, and the thickness of silicon layer is 1～3 micron.
Wherein, release silicone oil is commercially available product, such as Dow corning 7362 silicone oil.
Preferably, the thickness of described aluminium foil is 20～25 microns.
The beneficial effects of the utility model are:
The aluminium foil mould release membrance that the utility model proposes, because aluminium foil has preferable release effect after being coated with silicone oil, therefore has the thermostability of brilliance, higher resistance to compression, plays the technique effect same with Copper Foil, and greatly reduce cost in substrate pressing.
Accompanying drawing explanation
Fig. 1 is the structure chart of this utility model embodiment 1 aluminium foil mould release membrance.
In figure, 1 is release silicon layer, and 2 is aluminium foil.
Detailed description of the invention
Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
In description of the present utility model, it should be noted that, term " " center ", " ", " laterally ", on " ", D score, " front ", " afterwards ", " left ", " right ", " vertically ", " level ", " push up ", " end " " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, it is for only for ease of description this utility model and simplifies description, rather than indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
Embodiment 1:
This superhigh temperature mould release membrance texture material is soft, ductility is good, has argenteous gloss, and its structure chart such as Fig. 1, base material is aluminium foil 2, is release silicon layer 1 above, and the thickness of base material is 23 μm, release silicon layer 1 thickness 1-3 μm.Release silicone oil uses Dow corning 7362 silicone oil.
The preparation process of aluminium foil mould release membrance is: after silicone oil is deployed, is unreeled by machine on aluminium foil, through adjustment and the control of tension control system, makes face tight smooth, through coating head web coatable, dry, cool down, rolling is shaped to superhigh temperature mould release membrance.
Silicone oil allotment is prepared according to silicone oil and the organic solvent of description of commodity, in mass ratio 1:6, adds subsidiary catalyst and firming agent in product and is stirred 20min, i.e. can be used for being coated with.
During coating, the conveying of anilox roll rotation direction and film trend is contrary, is coated with for the inverse time, and speed that anilox roll rotates and the speed ratio walking film are 105%, and silicone oil is driven by anilox roll and is spread evenly across aluminium foil top layer, i.e. obtains release silicon layer through drying to be fully cured.
Above embodiment is only to be described preferred implementation of the present utility model; not scope of the present utility model is defined; on the premise of without departing from this utility model design spirit; various modification that technical scheme is made by this area ordinary skill technical staff and improvement, all should fall in the protection domain that claims of the present utility model determine.
Claims (2)
1. an aluminium foil mould release membrance, it is characterised in that be that one layer of silicone oil is set on aluminium foil,
Described silicone oil is release silicone oil, and the thickness of silicon layer is 1～3 micron.
Aluminium foil mould release membrance the most according to claim 1, it is characterised in that described aluminium foil
Thickness be 20～25 microns.
