GC Ejecting Needles

GC ejecting needles are mainly applied to LED chip sorting machine and semiconductor IC die bonding for assembly process.

Applications:
1.GC ejecting needles are made of BeCu alloy material, whose inherent characteristics include high hardness, mechanical strength and low degree of wearing that make it suitable to be processed to ejecting needles.
2.The GC ejecting needles are specifically produced by Chinatungsten Online and are mainly used in LED chip sorting and semiconductor IC die bonding processes for preventing push-up damage to the chip bottom side.
3.Depends on variant die dimension and aspect ratio, the requested spec of tip radius and structure design is changed accordingly.
