Description
Technical field
The invention belongs to the making field of stereoscopic circuit board, more precisely, relate to a kind of in three-dimensional polymer surface making or the technology of repairing stereo circuit.
Background technology
In recent years, along with the fast development of electronics industry and the extensive use of macromolecular material, polymer surface local selective metallization has attracted increasing concern in the making of electronic device, the field such as reparation and encapsulation.Electric equipment products continues the development to directions such as digitlization, lightweight, small lot, flexibility, multifunction, intellectuality, high reliability, low energy consumption, further promotes at polymer surface making and the rapid advances repairing conducting wire technology.
Traditional polymer surface local metallization technology, as injected complex technique, hot press printing technology and traditional print circuit plates making technology etc., usually there is the shortcomings such as complex manufacturing technology, raw material loss is large, environmental pollution is serious, and the requirement of the manufactures such as small lot, high accuracy and flexibility can not be met.For this reason, domestic and international researcher attempts one after another high for flexibility degree, be applied to surface of polymer material three-dimensional conductive circuit without the need to the laser processing technology of mask making with in repairing.
Three dimensional mold interconnecting device (three dimensional molded interconnect devices, 3D-MID), refer to have the moulded component of mechanical function as substrate, by at the direct arranging electronic circuit of piece surface, being coupled together by discrete electronic component at three dimensions, is the device of an organic whole by machinery and the function i ntegration of electronics.3D-MID technology can by the function i ntegration such as support, protection of the electric interconnection function of common circuit board, the supporting function of components and parts and plastic casing on a device, form circuit carrier that is three-dimensional, that integrate dynamo-electric function, its application relates to automobile, communication, household appliances etc., and also has development prospect widely in medical field.The technical process of 3D-MID can be divided into injecting forming structure part, generate assembling three part of metallic circuit and electronic devices and components.Wherein, the generating mode of metallic conduction circuit is the research emphasis of academia always.As laser three-D circuit straight forming technology (the Laser Direct Structuring that German LPKF D. O. O. develops, LDS) development in recent years is very rapid, its core process is by a kind of plastics batch mixing and laser activation metal component compound that some are special, be injection molded into and there is thermoplastic processed element, when this component exposure is in laser, this laser activation metal component will be broken down into elemental metals (as copper, palladium, nickel or its mixture etc.) and remaining organic substance tissue, meanwhile, in the position of laser beam flying, the rough surface containing elemental metals particle can be left, these metallic particles using in follow-up chemical plating process as catalytic active center, deposit thickness on circuit is finally made to be the coated metal of 5 ~ 8 μm.The advantage of this technology is that technique is convenient, reliable, and laser beam directly can be write according to cad data, and production process flexibility degree is high, and at present, this technology realizes commercialization, and has successfully produced the products such as hearing aids, car antenna, antenna for mobile phone.But this technology also exists obvious shortcoming, namely this technology must adopt the particular plastic with LDS performance, expensive, and has only used the laser activation metal component on moulding surface, causes the waste of most of activated metal.
Patent documentation (patent No.: ZL200810197225.5) also discloses a kind of laser direct-writing and micro-melting and coating technique of utilizing and makes and repair the method for conductive circuit of three dimensional mold interconnecting device.Its general principle directly writes technique for utilizing micro-pen or micro-spray, or the mode such as spraying, mask plate silk screen printing, according to designed line pattern, at the electric slurry that molded structural member surface preset one deck 0.1 ~ 50 μm is thick, after low temperature drying slurry organic solvent, adopt infrared laser (as ND:YAG laser and CO2 laser etc.) along the track irradiation pulp layer of electric slurry again, form the preliminary profile of conductive circuit pattern, then rely on chemical plating process to form the conducting wire with high-bond and superior electrical conductivity, resistance to wear, oxidative resistance and corrosion resistance.Utilize this kind of technology can produce metallic circuit respectively on tens kinds of polymeric matrixs such as polystyrene (PS), polyethylene (PE), polypropylene (PP), polyimides (PI), and to basis material without platability requirement, can prepare and repair various complicated conducting wire fast, flexibility degree is high.But the major defect of the method is that working (machining) efficiency is low, is difficult to making in enormous quantities; In addition, infrared laser can cause certain damage to matrix itself, and when its heat affected area can cause subsequent chemistry to be plated, the selectivity of figure reduces; And electric slurry is as the requisite raw material of this method, also have impact on the range of application of this technology.
In laser-induced deposition technical field, laser-induced chemical gas phase deposition technology at multiple deposited on substrates various metals, but can need vacuum condition, and equipment manufacturing cost is expensive, and gas toxicity is large; The shortcoming of induced with laser solid precipitation technology is that depositing electrically conductive lines are thinner, in uneven thickness, poor with basal body binding force; The advantages such as laser-induced chemical liquid-phase deposition technique has simple to operate, and technological process is few, but also there is the too thin shortcoming of plated metal layer thickness.
