Abstract
The invention discloses a cleaning process of a coating surface of an electronic device. The cleaning process is characterized by comprising the steps of: (1) degreasing: adding 10% an industrial detergent into water, and ultrasonic cleaning for 20 minutes; (2) washing (tap water), and rinsing for 5 minutes; (3) drying; (4) sandblasting to remove an oxidation film: spraying clean quartz sand on the surface of a workpiece; (5) degreasing: adding 10% the industrial detergent into the water, and ultrasonic cleaning for 20 minutes; (6) primary washing (tap water), and ultrasonic rinsing for 2 minutes; (7) secondary washing (purified water), and ultrasonic rinsing for 2 minutes; (8) tertiary washing (purified water), and rinsing for 2 minutes; (9) drying at 120 DEG C; (10) washing (deionized water), and rinsing for 1 minute; (11) drying at 150 DEG C; and (12) linear ion source irradiation in a vacuum container: lasting for 5 minutes, with the air pressure being 0.5Pa, the ion source voltage being 1500V, and the bias voltage being 600V. The cleaning process has the advantage of high environmental protection property, and is beneficial to the improvement of the binding force between a subsequent coating and a substrate.
Description
Technical field
The present invention relates to the manufacture field of electron device, particularly a kind of for communication, radar, electronic applications passive RF and the cleaning of microwave filter, duplexer coated surface.
Background technology
Passive RF is widely used in microwave filter, duplexer and communicates by letter, radar, electronic applications, is one of components and parts very crucial in the wireless telecommunication system.This class device all is take aluminium as matrix at present, and the certain thickness copper of its electroplating surface and silver satisfy service requirements to improve its surface conductivity.Because aluminium is comparatively active metal, workpiece all can be looked unfamiliar into the thin or thick very fine and close pellumina of one deck in its change before plating.
In electroplating technology, need workpiece is carried out oil removing before the plated film, the deoxidation film is processed.General method is the alkali cleaning oil removing at present, and strong acid is removed its surface film oxide.The use of strong acid has not only increased cost, the most important thing is to cause serious environmental pollution, and the dilution discharge of strong acid has also caused havoc to water and soil.
Summary of the invention
The present invention the invention provides a kind of cleaning of electron device coated surface in order to address the above problem.
As preferably, described electron device is wave filter or duplexer.
As preferably, described electron device is passive RF and microwave filter or duplexer.
As preferably, described electron device coated surface is aluminum substrate.
Cleaning provided by the invention comprises following steps:
(1). oil removing: water adds 10% industrial cleaning solution, ultrasonic cleaning 20 minutes;
(2). washing (tap water), rinsing 5 minutes;
(3). oven dry;
(4). the sandblast oxide film dissolving: clean quartz sand sprays workpiece surface;
(5). oil removing: water+10% industrial cleaning solution, ultrasonic cleaning 20 minutes;
(6). first washing (tap water), ultrasonic rinsing 2 minutes;
(7). second washing (pure water), ultrasonic rinsing 2 minutes;
(8). the 3rd road washing (pure water), rinsing 2 minutes;
(9) .120 ℃ of oven dry;
(10). washing (deionized water), rinsing 1 minute;
(11) .150 ℃ of oven dry;
(12). linear ion source irradiation in the vacuum vessel: air pressure 0.5Pa, ion source voltage 1500V, bias voltage 600V, 5 minutes time.
The invention beneficial effect:
Purpose of the present invention and distinguishing feature are:
At first, utilize industrial detergent to replace alkali cleaning to remove greasy dirt and other dirt settlings on aluminum products surface.Reduce alkali lye to the pollution of environment.
Secondly, utilize the method for machinery to replace pickling to remove the comparatively thick close oxide film in aluminum products surface, thoroughly get rid of acid solution to the pollution of environment.
Moreover, utilize high energy argon particle that workpiece surface is bombarded, can effectively remove remained on surface impurity and thinner oxide compound, and form the concavo-convex of microcosmic on its surface, be conducive to improve subsequent plating layer and basal body binding force.
