Description
Technical field
The present invention relates to Novel patch formula components and parts, specifically a kind of paster switch, more specifically SMD elastomer touch-switch.
Background technology
Nearly all electronic product all needs to have touch-switch.Use at present the silica gel touch-switch of silica gel and elastic caoutchouc a lot, as telephone set, mobile phone, computor-keyboard, remote controller, controller etc.Present touch-switch criteria of right and wrong part, generally all with angle and Position Design, for example, in order to assemble use, first to offer in the circuit board corresponding location hole, in practical set process, need by artificial location and assembling, by manually the angle of each switch being passed to wiring board location hole.In order to improve efficiency of assembling, also have and complete assembly work with equipment.
Rely on artificial location and assembling, inefficiency, cost of labor is high, and needs larger operation place.Use equipment assembling can greatly improve efficiency of assembling, but on touch-switch or the basis of non-standard component, the touch-switch that equipment can only supporting a few kind, thereby cause a large amount of wastings of resources and overlapping investment.
SMT paster refer on PCB basis, process the abbreviation of series of processes flow process.PCB(PrintedCircuitBoard), Chinese is printed circuit board, claims again printed circuit board (PCB), printed substrate, is important electronic unit, is the supporter of electronic devices and components, is the supplier of electronic devices and components electrical connection.Because it is to adopt electron printing to make, therefore be called as " printing " circuit board.(be electronic circuit surface mounting technology or surface mounting technology and SMT is surface installation technique.SMT is the abbreviation of SurfaceMountedTechnology), most popular a kind of technology and technique in current Electronic Assemblies industry, it is that one will (be called for short SMC/SMD without pin or short leg surface-assembled components and parts, Chinese claims sheet components and parts) be arranged on printed circuit board (PrintedCircuitBoard, PCB) on surface or the surface of other substrate, by the in addition circuit load technology of welding assembly of the method such as reflow welding or immersed solder.Under present environment, electronics technology revolution is imperative, electronic product is pursued miniaturization, electronic product function is more complete, the perforation plug-in element of former use cannot dwindle, integrated circuit (IC) particularly extensive, high integrated IC in the situation without punctured element, adopts surface patch element to become already a kind of inevitable.In standardization, mass, automation, low cost, high yield, high quality epoch, this surface installation technique of SMT and technique will obtain development greatly and generally application.The advantage of SMT paster processing: packaging density is high, electronic product volume is little, lightweight, and the volume and weight of surface mount elements only has 1/10 left and right of traditional inserting element, after generally adopting SMT, electronic product volume-diminished 40% ~ 60%, weight saving 60% ~ 80%; Reliability is high, vibration resistance is strong; Welding point defect rate is low; High frequency characteristics is good; Electromagnetism and radio frequency interference are reduced; Easily be automated, enhance productivity, reduce costs and reach 30% ~ 50%; Save material, the energy, equipment, manpower, time etc.
The SMD components of present stage has patch capacitor, inductance, resistance, diode, triode and IC class, there is not yet SMD elastomer touch-switch.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of SMD elastomer touch-switch is provided, to adapt to the development of electronics technology, meet the need of market.
SMD elastomer touch-switch of the present invention, comprises matrix and electric conductor, and its basis material is macromolecular material, and switch entirety meets the volume requirement of SMD components, and switch is provided for the syndeton fixing with printed circuit board.
The macromolecular material here comprises: silica gel, fluorubber, nitrile rubber, ethylene-propylene rubber, butadiene-styrene rubber, neoprene, butyl rubber and natural rubber.Wherein taking silica gel as first-selected.
Described electric conductor is selected from: metallic conductor and plating metal on surface electric conductor, surface spraying metallic conductor, conductive carbon, conducting resinl and electrically conductive ink.Especially, in the occasion of forceful electric power, and requirement contact is good, stable, sensitivity requires in high situation, and the electric conductor of conducting metal and plating metal on surface, surface spraying metallic conductor are preferred.Wherein plating metal on surface comprises silver-plated and gold-plated.The anti-oxidant especially and non-corrosive of this electroplate and gold-plated electric conductor, thereby very suitablely under moist environment, use.
Described syndeton refers to: pin, retainer plate, support, framework, skeleton or their combination.
Of the present invention and syndeton (pin, retainer plate, support, framework, skeleton or their combination), with existing surface mount elements as the pin of Chip-R, patch capacitor etc. be diverse concept.The pin of Chip-R, patch capacitor etc. belongs to a part for circuit, is to lean on pin conduction, and in the present invention, does not need to conduct electricity by syndetons such as pins.Of the present invention and the effect of syndeton, be for touch-switch is fixed on to printed circuit board, the just fixation rising.Thereby the syndeton of SMD elastomer touch-switch of the present invention just has a variety of forms, as pin, retainer plate, support, framework, skeleton or their combination etc.Just because of of the present invention and the just fixation that rises of syndeton, so the material of syndeton just can be varied, in the present invention, the material of described syndeton is selected from: metal, plastics and rubber.
When in specific embodiments, when syndeton is taked the form of pin, described in it, the quantity of pin is advisable with 2 ~ 4.
Syndeton described in the present invention by bonding, riveted joint, clamping matching, be spirally connected, mosaic mode or directly and mode and the touch-switch of basis material compression molding become one.
Consider that a switch uses the variation of function, SMD elastomer touch-switch of the present invention, is also included in a switch entirety multiple electric conductors is set.Multiple electric conductors are chpn level and arrange.Can arrive at most five levels.Such touch-switch in use, touches each time just can realize and connects different electrical equipment, or start in order the different function in same electrical equipment, accomplishes that one is multiplex.Such touch-switch is very suitable on the electrical equipment of the small and exquisite exquisiteness of volume.
The present invention also comprises that described SMD elastomer touch-switch is packaged into the pattern that meets SMD components packing instructions by the braid of employing paster standard.
The present invention is on the basis of existing touch-switch, by adding paster pin and paster retainer plate, patch support framework or skeleton, be able to carry out braid standard, carry out the relevant criterion volume requirement of SMD components, and can pass through the requirement of surface mounting technology automatic chip mounting equipment, and realize automatic continuous production assembling, replace traditional manual assembly and artificial cooperation, save a large amount of social resources, realize the effect of high efficiency and reduction development cost, manufacturing cost.And can form series standard part form by high unity, Promoting Standardized, promotes the development of industry.
In actual applications, corresponding line plate need arrange match with SMD elastomer touch-switch of the present invention corresponding for the solder joint or other sticking veneer that are connected and fixed, paste platform.SMD elastomer touch-switch is carried out assembling automatically by last resort chip mounter, welds or paste wiring board assigned address.
