Abstract

The invention provides a metallizing manufacturing method of a ceramic substrate, in particular to a film coating manufacturing way utilized because the ceramic substrate is an inorganic substance without any positive and negative electrical property and is very difficult to joint with metal. The film coating manufacturing way comprises the following steps of: firstly cleaning the ceramic substrate; carrying out roughening treatment on the surface of the ceramic substrate in a micro-etching way; and coating nanometer grade Si-containing surfactants on the surface of the ceramic substrate to enable the surface of the ceramic substrate, without electric polarity, to generate negative electrode effect. Therefore, a positively charged first metal layer which has thinner thickness and is easy to joint with ceramic can be deposited on the nanometer grade Si-containing surfactants in the film coating way, and the effect of effectively reducing the manufacturing cost of the ceramic substrate, which has fine heat positively charged, good electrical property, high reliability and strong bonding force, can be achieved.

Description

technical field

[0001] The present invention provides a method for metallizing ceramic substrates, particularly involving the use of nano surfactants to coat the surface of roughened ceramic substrates, so that positive and negative electrode effects can be produced on the surface of ceramic substrates that do not have electrical polarity. In this way, The first metal layer with a relatively thin thickness can be deposited on the ceramic substrate with the nano-surfactant through electroplating thin film, so as to achieve the effect meeting the market demand. Background technique

[0002] At present, with the rapid development of science and technology and the pursuit of higher quality of life, the application characteristics of many products tend to be extremely strict, making the use of newly developed materials a necessary means. Today's integrated circuit packaging is affected by the pursuit of better transmission efficiency and miniaturization (such as electronic compon...
