A kind of electronic circuit board 3D ink-jet printer of ultrasonic atomization nano suspending liquid
The present invention relates to a kind of electronic circuit board 3D inkjet printing field of atomization nano suspending liquid, be particularly applicable to directly print small semiconductor function device and 3D member.
In traditional PCB electronic circuit board manufacturing industry, no matter be common rigidity electronic circuit board or the production of flexible electronic wiring board in recent years, all will finally make by a series of complicated procedures of forming, common operation comprises the image of copper-clad plate, heavy copper, circuit, plating, etching, welding resistance, word and surface treatment etc.This mode of production, on the one hand, the input ratio of production equipment is larger, and very inconvenient for the production of small lot or the making of personalization, industrial waste gas and waste water that particularly plating and etching work procedure produce have all brought the broken ring to operator and environment.On the other hand, said electronic circuit board be all copper-clad plate taking plane as main, be difficult to implement online embedded plate-making for complicated 3D structure.
Recently for over ten years, it is an emerging technology that 3D printing technique is shooting up in manufacture field, this printing technique so-called " 3D printing ", " rapid shaping ", " manufacturing fast ", or " increasing material processing ".This manufacture method does not need proembryo and mould, just can be directly according to computer graphics data, and the method for printing stack material by layer generates needed parts, the plastics FMD melt extruded 3D printer of more common 3D Systems company.In recent years, along with scientific and technical development, there is titanium alloy powder, magnesium alloy powder, nickel-base alloy, Co-based alloy powder, the rapid shaping 3D metal printer of powder of stainless steel.This metalloid printer adopts the mode that laser or electron beam partial selectively melt SLS successively to print required parts, as the electron beam melting metal 3D printer of ARCAM company of Sweden, the lf metal 3D printer of Britain Renishaw, but can notice that these 3D printing devices are all taking print machinery type component as object, and not print electronic circuit board.
Recently, some scholar has proposed whether can complete the imagination that electronic circuit board is directly printed by common ink-jet printer, but can note the printing for microfine circuit, and common ink-jet printer is difficult to meet the requirement of industrial product in printing precision.Because common printing of inkjet printer shower nozzle is very little with the gap of printing goods, the electronic products of stereochemical structure is also not easy to realize.Because nano suspending liquid is different from the ink of common ink-jet printer, if use common ink-jet printer to be easy to make shower nozzle that the phenomenon of blocking occurs, the important indicator such as flow and viscosity that simultaneously also cannot On-line Control liquid, the solidifying and drying and also bring very large inconvenience as ink to subsequent handling.
Therefore; from above-mentioned background; can find to be necessary very much the electronic circuit board 3D ink-jet printer of the nano suspending liquid of inventing a kind of novelty; can directly print electric function parts, semiconductor components and devices and trickle 3D structure; comprise and print conductive layer, insulating barrier, protective layer, solder mask, and the 3D member of the functional part such as the resistance strain gage of wire, pad, resistance, inductance, electric capacity, diode, triode, operational amplifier and combination thereof, thermocouple, electronic mark, electronic antenna, FRID mark, SIM and trickle engineering.
