Description of the Invention (_) The present invention is a method for manufacturing an electronic product shell that blocks electromagnetic waves. It is mainly a method of coating with a metal organic contact medium to make When the casing of the electronic product is electroplated, more than one metal can be sequentially attached to the surface of the casing of the electronic product, thereby further enhancing the effect of blocking the electromagnetic wave (EMI) interference of the electronic product. According to the general practice, the plastic shell of electronic products is generally electroplated by insulating the plastic shell at a specific position after the step forming, and then drying it at a temperature of 50 ° C ~ 609C for 10 ~ 20 minutes, and then After degreasing, and washing the surface with water, roughen the surface with high concentration chromic acid (Cr), then wash with water, and then neutralize with lye, then perform acid leaching, sensitization, activation, and cleaning After the treatment, copper is attached to the surface by electroplating, and the surface is washed with water. After the surface is repeatedly activated with acid, nickel is adhered to the surface by electroplating, and then heated. After the surface is washed with water, it is dried at a temperature of 50 ° C ~ 60 ° C for 1 ~ 2 hours. In this way, although two metals, copper and nickel, can be recorded on a plastic case, the aforementioned method will still be as follows: Disadvantages: (1) · Because only part of it is absolutely treated, other places will have the copper, nickel and other metals attached (including inside and outside the shell), so not only the manufacturing time is long , And the cost is also high. (2) · Because of the nickel plating, the surface of the shell must be painted to increase the appearance of the shell. However, due to the poor adhesion of the outer layer of nickel sprayed on the outer surface of the shell, it often occurs. The paint peeling occurs, and when the coating operation is carried out, it will pollute the surrounding environment to a certain extent, and environmental protection problems will arise.纸张 This paper size is applicable to China National Standard (CNS) A4 specification (210X297 mm).

Description of the Invention (3) For the method, please refer to the first circle. The method includes the following steps: (1) · Tu Wei (Base Coat): It will contain more than one metal with different potentials. In this embodiment, it is silver, iron, nickel, palladium, titanium, aluminum, zinc, copper and other metals (but those who are familiar with this technology can still use other metals. Replaced.) Of the metal organic touch media, Tu Wei in the injection molding of the electronic product housing (plastic in this embodiment) specific place, in this embodiment is on the inner surface of the housing. (2) Drying: Put the carboxyl groups outside the coated medium into a drying device at a temperature of 50U0: and bake for 1 ~ 2 hours to dry it. (3). Wetting: Re The dried shell is treated with a solution containing a surfactant, which can effectively reduce the surface tension of the solution (in this example, water), such as from 70dynes / cm to 30 dynes / cm; further, the humidity can be adjusted. The surface of the metal-organic contact medium on the outer surface is strengthened to improve its hydrophilicity, and then washed with water. (4) · Acceleration (Leaching): The shell after cleaning is immersed in an experimental mixed medicine (acid tritium value 10 ~ 12, in this example, it is immersed in sodium hydroxide (NaOH) for 1 ~ 10 minutes. Effectively peel off the excess resin on the surface of the contact medium on the shell, so that the metal catalyst in the medium is exposed, and then the chemical copper precipitation reaction is accelerated, and then cleaned with water. (5) · Plating Copper (Electroless Copper): In a non-electrolytic manner, the copper metal is deposited on the outer surface where the contact medium is coated, so that the copper can be adhered to the place tightly, and then cleaned with water. (6) Initial (Initidtor): The shell is mixed with palladium (Pd), ruthenium (Ru), rhodium (Rh) metal and chelating etch (in this example, vaporized palladium and chlorine) Paper size applicable to China National Standard (CNS) A4 size (210X 297mm) gutter (please read the precautions on the back before filling this page) 477162 Printed by the Consumers Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 5. Description of Invention (4) Ruthenium Chemicals , Gasification 姥) treatment, 俾 can change the electricity of copper on its surface Position, so that chemical nickel can be precipitated sharply, and the chelating agent can dissolve the dissolved copper metal, which will not combine gas ions into gasified copper and shorten its service life, which can effectively prolong its service life. Know the life of the shell is 3 ~ 6 times, and then clean it with water. (7) · Nickel plating (Electroless Nickel): the shell treated in step (6), the service life is generally known as acidic products 5 ~ 10 times, and the precipitation is slower than the conventional acidic products and the sample is made of alkaline nickel-phosphorus alloy (NiP) for electroplating, so that the nickel-gold alloy is electroplated at the place coated with the contact medium, so that the nickel can adhere tightly After the copper metal is placed there, reduce the copper metal's contact with air and moisture to avoid copper oxidation, which will cause resistance, and then clean it with water.
