Description

Electronic Ceramic Components / Ceramic Electronic Parts

1. Description:

Much of the processing and assembly of electronic ceramics are done in areas of the world with very low labor costs. This includes the four types of companies identified in Section 1. These companies make most consumer products, PCBs, and virtually anything with discrete, leaded components. A ‘green’ company with plants all over the world uses the same environmental controls everywhere, making the most stringent regulation a de facto worldwide standard. It also requires vendors and suppliers to do the same. This pressures smaller electronics companies working for large ‘green’ ones to also be environmentally conscious.

2. Feature Advantages:

1) High hardness and high density

2) Low thermal conductivity

3) Chemical inertness

4) Good wear resistance

5) High Fracture toughness

6) Good insulation performance

7) High temperature resistance

8) A variety of specifications is available

9) Satisfy various technical requests

10) Lower medium spoilage

11) Stiffness texture

12) Chemical inertness

13) Good wear resistance

14) High Fracture toughness

15) Good insulation performance
