Metallized Ceramic Insulator
In recent years, with the rapid development of integrated circuit technology, metal-Ceramic Insulator packaging forms have been increasingly used and occupy a place in the packaging field.
The structure of this type of package shell is basically the same, generally consisting of a base, a frame, a ceramic insulator, leads and solder. In order for the brazing to proceed smoothly, the sealing surface of the insulator in the shell (such as the contact surface between ceramic and parts) must be metallized. This process is called Ceramic metallization. We currently produce a wide range of Metallized Ceramic Components.

About Air Tightness
-
Why Air Tightness Is Important for a Metallized Ceramic InsulatorAir tightness is one of the important indicators to measure the quality of Metallized Ceramic Insulator. Air leakage is the main reason for the failure of metal-ceramic insulator packaging shells.
-
What are the reasons for air leakageThe main reasons of air leakage are: 1. Ceramic insulators have quality problems before metallization, which causes air leakage in the insulator itself. 2. Some ceramic insulators are too small (to match the size of metal parts). 3. Problems such as the metallization layer on the sealing surface of ceramic insulators falling off and ceramic being exposed.
-
How to improve air tightnessAir sealing performance can be improved from the following two aspects.1. Strict Control in Production: Products with unqualified quality are strictly prohibited from entering the metallization process.
2. 100% Full Inspection Before Shipment: Pick out insulators that are undersized or have metallization layer defects.
