The tungsten ejecting needle of the crystal bonding machine is a tungsten steel part specially designed for use in the crystal bonding machine (also known as the crystal fixing machine). A die bonder is a device used to secure semiconductor chips or crystals to a suitable location or substrate. In the die bonding machine, the tungsten steel thimble plays a very important role.
Tungsten steel is a high-quality alloy steel with high hardness, high strength, high wear resistance and excellent corrosion resistance. Therefore, it is widely used to manufacture high-precision, high-demand tools and parts. In the field of die bonding machines, tungsten ejecting needles are used as an auxiliary tool to accurately place semiconductor chips or crystals on the substrate.
The structure and shape of the tungsten ejecting needle of the die bonding machine varies according to different designs and uses. Generally speaking, they all have the following characteristics:
1. High precision: Tungsten ejecting needles have very high manufacturing precision to ensure that there will be no positional deviation or unevenness when placing chips or crystals.
2. High strength: Because tungsten steel has high strength and hardness, tungsten ejecting needle can withstand high loads and long-term repeated use, and are not easily deformed or damaged.
3. Corrosion resistance: Tungsten ejecting needle have excellent corrosion resistance and can resist the erosion of various chemical substances, thus ensuring their long service life.
4. Good thermal conductivity: The tungsten steel thimble has good thermal conductivity and can conduct the heat generated by the chip or crystal away, thereby avoiding equipment failure caused by excessive temperature.
In addition to its application in die bonding machines, tungsten ejecting needles can also be used in other fields. For example, in lathes and grinders, tungsten ejecting needle can be used as high-precision cutting tools and grinding tools; in the optoelectronic industry, tungsten steel electrode rods are widely used to manufacture products such as LED lamps and displays.
