Nozzle
The rapid development of microelectronics technology has put forward higher requirements for electronic packaging. Non-contact dispensing, as a dispensing method currently under major development, is widely used in electronic packaging processes such as chip fixation, bottom filling, and LED packaging. The trajectory and positioning of the dispensing are determined by the dispenser's control system.As executive components, the nozzle and impact pin have a direct influence on the size, diameter, and precision of the adhesive dots. With the continuous increase in dispensing operating frequency, higher and higher demands are being placed on the material, dimensional accuracy, and surface roughness of nozzles and impact pins.Our company's main products are high-precision nozzles and impact pins, utilizing super-hard materials such as cemented carbide, sapphire, and polycrystalline diamond. With dimensional accuracy reaching ±2 μm and surface roughness achieving Ra 0.1 μm, we have become a primary force driving the localization of similar products.
Plunger
A chip pickup tool, the impact pin is a very important component in the electronics manufacturing industry. It is used to eject adhesive from the dispensing gun and plays a key role in the assembly and packaging of electronic products.
The aspects are as follows: controlling the glue flow rate and spray position to ensure glue precision and consistency; protecting the nozzle from clogging or wear, extending the service life of the nozzle; improving production efficiency and reducing production costs. In the future, with the continuous improvement of requirements for high density, high speed, and high reliability in electronic products, impact pin manufacturing technology will also develop continuously. For example, utilizing advanced materials, processing, and coating technologies can manufacture impact pins that are more wear-resistant, corrosion-resistant, and highly precise.
Laser Welding Nozzle
The solder ball nozzle is a nozzle used for welding and surface treatment, mainly applied in the following industries:
Electronics Manufacturing: The solder ball nozzle can be used for surface mount soldering of printed circuit boards and electronic components.
Automotive Manufacturing: The solder ball nozzle can be used for welding and surface coating treatment in automobile manufacturing.
Medical Device Manufacturing: The solder ball nozzle can be used for surface coating treatment and welding of medical devices.
Precision Instrument Manufacturing: The solder ball nozzle can be used for surface coating treatment and welding in precision instrument manufacturing.
Capillary
In chip packaging scale, connecting the chip pins to the external circuit, and connecting the packaged components to the system, most are achieved through wires of different materials, different cross-sectional shapes and sizes, using the method of "Ultrasonic Thermocompression Bonding". This method is also called "Wire Bonding". The equipment used is a wire bonder, also known as a wire welding machine. The tool used by the machine—called a Capillary, also known as a Stitch Bond.
In different application scenarios, there also exists "Pure Thermocompression Bonding" where ultrasonic energy is not applied to the bonding wire. Thermocompression bonding adheres the wire (mostly gold wire and copper wire) under the action of heat, pressure, and time. This bonding process requires higher temperatures.

Precision Herringbone Groove Bearings Manufactured by Our Company
Hydrodynamic sliding bearings, which generate load capacity through fluid dynamic pressure effects, are widely utilized across various applications due to their advantages of low frictional losses, reliable performance, and high oil-film stiffness.Compared to sliding bearings with other groove geometries, herringbone-groove bearings exhibit higher oil-film stiffness. Consequently, they are primarily employed under high-speed, light-load operating conditions. Such working environments demand exceptional bearing stability and minimal frictional losses. It is evident that the structural design of the bearing has a significant impact on its overall performance.
