Description
Technical field
The present invention relates to aluminium base manufacturing technology field, it is specifically related to that a kind of aluminium base is special goes membrane concentration liquid and its preparation method and using method.
Background technology
Within 1969, aluminium base copper-clad plate (hereinafter referred to as aluminium base) manufacturing technology has been invented by SANYO GS company, and amplifies hybrid integrated circuit in 1974 for STK series high-power. Aluminium base is a kind of metal-based copper-clad plate with good heat radiating function, and general single sided board is made up of three-decker, is circuit layer (Copper Foil), insulation layer and metal-based layer respectively. Being designed to dual platen for also having of high-end use, structure is circuit layer, insulation layer, aluminium base, insulation layer, circuit layer. Only a few is applied as multi-ply wood, it is possible to by common multi-ply wood and insulation layer, aluminium base laminating and become.
There is the performances such as excellent electric property, thermal diffusivity, electromagnetic wave shielding, high withstand voltage and bending machining due to aluminium base, thus the relevant industries such as high-power LED illumination, power supply, automobile, computer, aviation electronics, medical treatment it are widely used in, the upsurge that aluminium base copper-clad plate (i.e. aluminium base) has worldwide started research and development and produced, large quantities of representational metal substrate producer occurs, such as Japan Sumitomo, Japan Panasonic electrician, Bei Gesi company of the U.S. etc.
In the making processes of aluminium base, the transfer of line pattern is necessary step. Realizing line pattern transfer, the use of photo-resist plays a part most important. Along with the development of technology, light actuating resisting corrosion dry film has the performance of good processing performance, excellent imaging and chemical-resistant resistance due to it, and then progressively instead of photo-resist, is applied in line transitions. Light actuating resisting corrosion dry film is primarily of protective membrane, photoresist film, Carrier polyester film composition. But after " imaging " completes, can photoresist film be removed smoothly completely, can directly affect again the rear operations such as etching.
In routine techniques, general use inorganic alkali solution is as moving back film agent, as: the aqueous solution etc. of the 3-4% of NaOH, KOH, but there is following shortcoming in it: one is to attack tin, copper coating, makes it variable color, stains gold face etc.; Two is move back at fine-line to cause tin to move in membrane process, has residual copper during etching, causes short circuit between circuit, and product qualified rate is low; Three is that the film slag that sodium hydroxid produces when moving back film is excessive, it is difficult to filters, is not suitable for machine and moves back, move back membrane efficiency lower; Four is that in dry film, photo-resist polymkeric substance dissolves in because using sodium hydroxide and useless moves back film liquid, causes waste liquid to be difficult to process, the problems such as contaminate environment; Five need to add the auxiliary agents such as butyl Cellosolve (ButylCellusolove, BCS) or trolamine when being move back film separately, and to improve it to the solubility property of dry film, it is to increase move back film effect, and butyl Cellosolve class is toxicity higher building matter.
Thus produce a kind of can efficiently peel off photoresist film on aluminium base and can not affect move back film after base material quality remove film liquid, become the active demand of aluminium base manufacturing.
