More information
Striving for perfection and belief of “Quality First”
Sorting and die bonding technologies are the key processes in LED chip production and semiconductor IC assembly. While, ejecting needles are necessary and significant for dies releasing from tapes without damage. G.C Micro provides variant kinds of ejecting needles always with the belief of “Quality First” and obey ISO 9001 quality management system for customer satisfaction.
Product Information
• Applications:
- The inherent characteristics of tungsten carbide include extremely high hardness, mechanical strength and low degree of wearing that make it suitable to be processed to ejecting needles.
- The tungsten carbide ejecting needles are widely used in LED chip sorting and semiconductor IC die bonding processes.
- Depends on variant die dimension and aspect ratio and special concern of without damaging to the dies, the requested spec of tip radius and structure design is changed accordingly.
