Embodiment 1

[0034] Dissolve 0.94g of copper nitrate in 100mL of water to prepare a 0.05mol / L copper nitrate solution, adjust its pH to 11 with concentrated ammonia water, take out 10mL, add isopropanol and polyvinyl alcohol to dilute the 0.05mol / L copper nitrate solution to The concentration of water / isopropanol / polyvinyl alcohol mixed solution is 0.01mol / L solution, wherein the dosage of polyvinyl alcohol is 0.2g. Nitrogen was blown into the solution for 5 minutes to remove oxygen. Add 12g of polyacrylic acid resin to the solution that has been deoxygenated, print a pre-designed circuit on the insulating substrate of the flexible circuit board with screen printing, and then move it to 60Gy / min gamma rays (Shenzhen Changyuan Company's γ-ray irradiator) for 3 min.

[0035] Electroless copper plating is then performed. Plating solution composition: 200ml water, 2.0g copper sulfate pentahydrate, 2ml formaldehyde, 6gEDTA 2Na, 4g potassium sodium tartrate, adjust the pH value to 12.5 with Na...

Embodiment 2

[0037] According to the method of Example 1, the difference is that the copper circuit is plated on the insulating substrate of the rigid printed wiring board.

Embodiment 3

[0039] According to the method of Example 1, the difference is that the solution after adding the polyacrylic acid resin is spin-coated on the ceramic surface by the spin-coating film-forming method. Subsequent steps of γ-ray radiation and electroless plating are the same. The process parameters of spin coating film formation: 800 rpm, 5s.

Abstract

The invention provides a method for preparing a non-metallic component with a metalized surface by utilizing gamma ray, comprising the following steps: a). preparing solution containing metallic ionswhich adopts solvent as polar solvent; b). evenly distributing the solution of step a) in a preset area of the non-metallic component according to a preset shape; c). utilizing gamma ray to radiate the area distributed with the metallic ionic solution on the non-metallic component of step b); and d). utilizing chemical plating to plate a metallic layer on the area radiated by gamma ray in step c).The method overcomes the disadvantages of complicated operation and environmental pollution of the traditional chemical agent method for roughening the surface of nonmetal, and metallic plating withgood adhesion can be formed on inorganic nonmetallic materials such as glass and ceramic and the like with large surface hardness.

Description

technical field [0001] The invention relates to a surface metallized non-metallic part and a manufacturing method thereof. Background technique [0002] Surface metallization of non-metallic parts by electroless plating is a common technology for non-metallic parts processing. In the prior art, the surface metallization process of non-metals is: surface degreasing-(mechanical roughening)-chemical roughening-sensitization-activation-electroless plating. For inorganic non-metals such as glass, ceramics, and stone, mechanical roughening is also required; plastics and some decorative parts with high surface roughness requirements, as well as complex-shaped, small-sized, and thin-walled parts, only use chemical roughening. This method is cumbersome, the roughening agent is often strong acid or strong alkali and the formula is complex, the requirements for process conditions, such as temperature, etc. are high, and the adhesion of the obtained metal coating is often low. [0003...
