Description
Technical field
The present invention relates to a kind of FPC combined type mould release membrance technical equipment field, particularly to a kind of FPC
Pressing is high temperature resistant combined type mould release membrance and preparation method thereof.
Background technology
FPC is the abbreviation of Flexible Printed Circuit, also known as FPC, flexible print
Printed circuit board, flex circuit application, have the advantages that distribution density is high, lightweight, thickness is thin；It is main
Use at a lot of product such as mobile phone, notebook computer, PDA number video recorder, LCM.Along with civilian
The further development of consumer electronics, requires more and more higher to the technology of FPC.
In existing FPC production process, the high temperature resistant mould release membrance used, by auxiliary with remaining pressing for FPC
The tympan of material isolation, referred to as mould release membrance, TPX is the abbreviation of Transparent Polymer X,
TPX is trade name, and the chemistry of its raw material is entitled: PMP, poly-4-methyl-1-pentene, the most poly-methylpent
Alkene；The mould release membrance manufactured by TPX is a kind of transparent and heat-resisting polyene macromolecular material, from performance
Upper also referred to as high temperature resistant resistance glue mould release membrance (Temperature Plastic-film Resistance).
Generally mould release membrance performance should possess three requirements:
1. temperature tolerance, in FPC bonding processes, pressing-in temp is about at about 180 DEG C
2. separation property, after FPC pressing, need to separate FPC so that after carrying out with consumables associated therewith
Continuous operation, this just need to need good separability by consumptive material contacted with FPC；
3. resistance colloidality, covers between mould and copper foil circuit, stiffening plate and copper foil circuit in FPC pressing
There is one layer of glue, play more preferable adhesive effect, when pressing, need to reduce by this layer of colloid as far as possible and be spilled over to
Copper foil surface, the performance reducing colloid spilling is resistance colloidality.
But the mould release membrance material used in existing FPC pressing production the most only meets separation property, resistance
In colloidality, temperature tolerance one or two characteristics, and can not be to meet these three characteristic requirements, simultaneously
Such as PMP material product, temperature tolerance is fine with separation property, and but resistance colloidality is poor, therefore, existing
FPC actual production is difficult to meet Product processing demand, it is generally required to arrange in pairs or groups two or more not simultaneously
Same mould release membrance product, or use the fluorine material that price is higher to meet FPC quality requirements, as made
With high-end mould release membrance product, production cost will be greatly improved, and use many moneys mould release membrance with the use of,
Also cost can be caused to increase, and cause production process operation inconvenience, and then affect production efficiency.
Summary of the invention
For solving above-mentioned technical problem, the invention provides a kind of high temperature resistant combined type of FPC pressing release
Film and preparation method thereof, overcomes the mould release membrance used in existing FPC pressing production not meet simultaneously
Separation property, hinders colloidality, the shortcoming of three characteristics of temperature tolerance, and provides one can meet separation simultaneously
Property, resistance colloidality, durothermic FPC pressing durable high temperature combined type mould release membrance material and manufacture method,
