The specific embodiment
The following describes the coating method of coated of tabular of the present invention and an embodiment of applying device thereof.
As coated of tabulars such as suitable printed circuit board (PCB) of the present invention, known printed circuit board (PCB) before using for example has through hole or/and the flat panel substrate of non-through hole, or does not have the substrate in these holes.Printed circuit board (PCB) wishes to use the substrate of thickness of slab 0.05mm~0.2mm before well-known.Have again, wish to use through hole or/and the flat panel substrate of non-through hole as this substrate.
Can enumerate a variety of as printed circuit board (PCB), for example on the substrate material surface of the plastic tab of glass-epoxy resin board with electrical insulating property etc., adhere to metal formings such as copper, aluminium, the method of perhaps utilizing vacuum evaporation is plated in substrate material surface with metals such as copper or electroconductive oxide of being representative with indium oxide-Xi (ITC) etc., form the compound conducting film at substrate material surface, have on the surface on the matrix material of electric conductivity, be provided with the position of through hole, for example with the substrate of copper coating at the inner formation of through hole conducting film; The substrate of the electroconductive circuit figure that on this substrate, forms with the method for taking a picture; On the substrate that forms conductive pattern such as metal, insulating resin layer is arranged, open non-through hole, comprising the substrate that forms conducting film on the insulating resin laminar surface of non-through hole inner face with copper coating etc. then with the method for Laser Processing or photograph; Use the substrate of the formation electroconductive circuit figures such as method of taking a picture on this substrate; Carry out the liquid resist of negative film photoresist, positive photoresist and the video picture of dry plate resist on this substrate and handle, form the printed circuit board (PCB) of electroconductive circuit pattern etc.
Use coating method of the present invention, by at the surface or the back side of printed circuit board (PCB), perhaps coating electrically conductive imparting agent in two sides can be removed the electric charge of accumulating on the printed circuit board (PCB), can use the liquid resist of electrostatic coating method coating then, on printed circuit board (PCB), form uniform resist layer.Apply the conducting film that this electric conductivity imparting agent forms, under the not drying regime before electrostatic coating, the specific insulation value of resist is 5 * 10 6Below the Ω cm, preferably 1 * 10 3Ω cm~2 * 10 3In the Ω cm scope.The value of specific insulation surpasses 5 * 10 6Ω cm then can not remove the electric charge of accumulating on the printed circuit board (PCB), can not form uniform resist with the coated liquid resist of electrostatic coating on printed circuit board (PCB) subsequently.The electric charge that is accumulated in addition in addition on the substrate can discharge, and makes the impaired shortcoming of circuitous pattern of copper.
In order to form above-mentioned not desciccator diaphragm state lower volume resistivity 5 * 10 6The conducting film that Ω cm is following as the electric conductivity imparting agent, for example can use the electric conductivity solvent separately, or previously used scolder with dissolving such as the resin of usefulness against corrosion or be dispersed in the electric conductivity solvent.
Such electric conductivity solvent dielectric constant will be more than 10, and preferably 12~35.In addition, wish it is volatile as this solvent, for example flat evaporator speed is below 0.2, preferably 0.003~0.2 organic solvent.Specifically can enumerate: for example, N-N-methyl-2-2-pyrrolidone N-, butyldiglycol, isophorone (3,5,5-trimethyl-2-cyclic ethylene-1-ketone), phenmethylol, D-sorbite, diacetone alcohol, diisobutyl ketone, dimethyl formamide etc.

In addition, the not enough 0.05MPa of figure atomizing pressure, the part that can occur not being coated with on the contrary, surpasses 0.3MPa, and the shape instability of injection can produce the problem that can not evenly apply.When so-called figure atomizing pressure is meant spraying and applying, the necessary air pressure of figure that from nozzle, sprays when spraying in order to adjust.
Except with the method for above-mentioned electric conductivity imparting agent spraying and applying to the printed circuit board (PCB), can also be at air atomizing pressure 0.1~0.6MPa, and air atomizing coating under the condition of figure atomizing pressure 0.2~0.6MPa.Spraying and applying under such medium-pressure or high pressure, the flow of atomised coating lacks in the time of can applying than low-pressure fuel injection.In this case, the atomised coating flow of hope is more than 50 liters/minute, and is best more than 50 liters/minute below 200 liters/minute, below 100 liters/minute.Under such coating condition, air atomizing insufficient pressure 0.1MPa is because it is uneven coating to occur, existence can not evenly be coated to problem on the printed circuit board (PCB) to liquid resist, on the contrary, surpasses the words of 0.6MPa, because printed circuit board (PCB) rocks, also there is the shortcoming that can not evenly apply.
This spraying and applying for example, can use air spraying and applying machine and airless injection coating machine etc.
