[Prior Art] In the prior art, a printed circuit board is used in a printing process to achieve a circuit pattern of a circuit board, and then a user places a circuit on the printed circuit board. The increased resolution requirements drove the traditional printed circuit board process to be improved. Most current printed circuit boards (pCB) use a film or a coating etch resist. After exposure and development, the exposed copper is removed by etching. The foil is formed into a circuit, and the resist is removed to complete the fabrication of the printed circuit board. However, as electronic products continue to be miniaturized and refined, more miniaturized and refined PCBs are needed, and the first PCB-based Fairy-light ink is used as a resist to eliminate traditional screen printing or other inkjet printing. The two roasting cycles required in the solution 'to increase PCB productivity and yield, the most critical of which is the ink used in the printing technology and its printing system. Therefore, it is necessary to provide a ray-type ink-type ink circuit. The secret is to achieve a copper-box-side printing circuit layout that can provide the ink on the printed circuit board. [New Content] The purpose of this creation is to provide an ultraviolet light-friendly ink circuit layout system that relies on the control element of the control element, and (4) the material can be environmentally friendly. 4 M413303 〆 I______

Wherein, the additive further comprises at least one of an emulsifier, an interfacial surfactant and an ultraviolet absorber; and the photopolymerization initiator is at least a cleavage initiator and a photoinitiator cation initiator. The ink 20 has a surface tension ranging from 22 to 24 Newtons per meter. Furthermore, the ink 2 is composed of a plurality of powder particles, and the size of the powder particles is a nanometer scale. For example, the size of the powder particles of the ink 20 is less than 3 nanometers. In one embodiment, The size of the powder particles of the ink 20 is between 5 nanometers and 1 (8) nanometers. In addition, the photopolymerization initiator in the ink 20 is a photoexcitable compound, that is, the ink 20 can be excited to be a radical after absorbing ultraviolet light, and transferred to a photosensitive molecule or a light source by energy transfer. a crosslinking agent that causes a photocuring reaction of the ink 2; and the photopolymerization prepolymer is also called an oligomer, which is a low molecular polymer containing an unsaturated functional group, and is the most important component of the ink 20 . Further, 'in terms of chemical structure', the photopolymerized prepolymer is a low molecular weight resin containing c = c unsaturated double bonds, and its average molecular weight is between several hundred and several thousand, for example, oligomer 7 M413303 I 100牟On June 24, the Yongzheng replacement system can be epoxy acrylate vinegar, polyurethane vinegar, vinegar vinegar, and domain soluble acrylic resin. Furthermore, the photosensitive single system is a small molecule compound having an unsaturated group (for example, a double bond), which can interact with the above-mentioned oligomer under ultraviolet light to crosslink 'the molecular weight is about several Between a few hundred and a few thousand. In addition, by adding a reactive diluent to the viscous prepolymer, the viscosity of the ink can be adjusted to control the curing crosslink density of the ink 2, thereby improving the physical properties after curing by ultraviolet light, for example, Softness and hardness. Wherein, the reactive diluent is classified into a monofunctional diluent and a polyfunctional diluent, and the polyfunctional reactive diluent is better than the monofunctional reactive diluent in terms of dilution effect and photocuring speed. Further, since the reactive diluent has an extremely important effect on the curing process of the ink 20 and the properties of the cured film, it is important to select a suitable reactive diluent. In general, the photosensitive monomer needs to take into consideration the physical properties such as viscosity, functionality, volatility, odor, toxicological properties, solubility, etc. depending on its needs. In general, a common reactive diluent may be tris(propylene) diacrylate (TPGDA), triethylene glycol diacrylate (TEGDA), 'trimethylol triacrylate (TMPTA), and the like. Further, since it is difficult to directly open the double bond of the photopolymerizable prepolymer by ultraviolet light, even in the case of no photopolymerization initiator, even a photosensitive material does not cure quickly. Therefore, in general, a small amount of the photopolymerization initiator is added to the ink 20, and when the ink 20 having the photopolymerization initiator is exposed to ultraviolet light, since the photoinitiator absorbs the photon, it decomposes to generate a radical and starts. The chain initiates the reaction, initiates the polymerization of the unsaturated double bond, and the polymer molecules are continuously crosslinked to form a network 8 wind 13303 L. The modified structure is modified on June 24, 100, and after the free radical loses activity and the growth of the chain is terminated. The ink is completely cured at 2 inches. Wherein, the photoinitiator may be the photopolymerization initiator, and is at least one of a cleavage initiator, a photoinitiator and a cationic initiator. The mixed solvent is used to dilute the ink 20' and is used to provide one of the inks. Further, the mixed solvent has a great influence on the stability of the ink 2 depending on the kind and amount thereof. Screening from low-boiling alcohols, high-boiling alcohols, ethers, cyclic amines, and cyclic vinegar organic solvents can significantly improve the stability of the ink 20, and selecting the optimal formulation to prepare the ink 20' The stability, viscosity, surface tension and electrical conductivity of the ink 2 are in accordance with the commercial performance requirements of the ink 20. In one embodiment, the mixed solvent is selected from the group consisting of ethyl acetate, butyl acetate, and isopropyl acetate. Finally, the circuit layout formed on the copper foil face 22 of the printed circuit board 2 is further washed by copper washing and alkali washing so that the circuit layout in which the ink 20 is laid is exposed on the printed circuit board 2. In contrast to the prior art, the present invention provides an ultraviolet light-friendly ink circuit layout system 10, which controls the positioning unit 14 by the control unit 18, so that the printing unit of the ultraviolet-friendly ink 20 is loaded. 16, according to the displacement of the positioning unit 14, can directly print a circuit layout on the printed circuit board 2, and expose and cure the ink 20 through ultraviolet light, and then through the steps of copper washing and alkali washing, etc. To expose the circuit layout to the printed circuit board 2. Therefore, the ink 2 by the present invention can be used to reduce the complicated steps such as pre-made mask sheets, copper foil coating, exposure and development, which are conventionally required for the prior art of the printed circuit board 2. Among them, the ultraviolet ring 9 M413303 'I 100 years of January 24 modified replacement type of ink 20 series environmentally friendly, storage safety, suitable for printed circuit boards and other hard substrates, wear resistance, resistance, heat, dry fast, low Halo, high resolution and other characteristics.
