Magnetic Collet
STRENGTH
Memory Semiconductor and Fingerprint Sensor Chip Pick up & Attach improves the void phenomenon. The combined role of back metal makes it easier to remove and attach the tool stably by magnetic force, and maintain flatness in the Attach process.
TECHNOLOGY
We are producing stable and high quality products with precise processing of Back Metal and Silicon Rubber with flatness of less than 50μm. -
Pick Up Pad
It is a pick-up tool that is used from molding to singulation test and packaging with minimum physical force with stable vacuum structure as a transporting silicon PAD used for semiconductor back process. We manufacture high-quality products from mold making to various shapes of designs.
-
Silicon Rubber Collet
STRENGTH
It is a soft silicon-based collet that can be applied as a pick-up water target, such as Scratch and Crack. It is manufactured by mold and is easy for mass production.
TECHNOLOGY– It is possible to implement the smallest domestic type Vacuum Hole 80um so that the smallest chip size pick up less than 100um can be done.
– It is optimized for the work which can endure the high temperature and the improvement of sticky phenomenon, and it is possible to extend the life time (life time) by developing the durable material.
– It is possible to implement customizing shapes of various designs Customer development request completion schedule includes sample development, design, mold, product production within 10 days.
-
Unplug Wire
Unplug wire helps decontamination of capillary holes and it is composed of strong tapered wire, which helps to extend the life of capillary and improve the quality.
