CDM material usually refers to a high-performance composite material, mainly made of glass fiber and anti-static high mechanical strength resin, with the following characteristics and applications:
characteristic
–CDM materials are resistant to high temperatures: It can maintain stable performance in harsh environments such as short-term exposure to 350 ℃ and continuous operation at 260 ℃, without problems such as layer separation, and can meet the requirements of high-temperature processes such as wave soldering and reflow soldering
-Dimensional stability: It can maintain good dimensional accuracy and mechanical performance even in environments with large temperature changes, ensuring the accuracy and reliability of fixtures and jigs during use
-Good mechanical performance: It has high hardness, strength, and impact resistance, wear resistance, compression resistance, and can withstand the external forces of frequent use of fixtures, extending its service life
-Anti static: It can effectively prevent the generation and accumulation of static electricity, avoid problems such as damage to electronic components and welding defects caused by static electricity, and ensure the quality of electronic product production
-Strong chemical stability: It has good corrosion resistance to common chemicals and is not easily corroded when in contact with chemical substances such as soldering flux. It can maintain stable performance in production processes in different chemical environments
-Low thermal conductivity: The relatively low thermal conductivity makes the heat transfer of the fixture slower during use, which helps reduce the impact of heat on electronic components and improve welding quality
application
Mainly used in the electronic manufacturing industry as tooling fixtures, such as insulation testing fixtures, wave soldering, reflow soldering, SMT surface mount, over furnace trays, over tin furnace fixtures, etc. It can also be used to manufacture trays, insulation boards, etc. for electronic equipment
