Introduction of the main exhibit products

Next generation packaging material nano solder particles


At the exhibition, HighChem will showcase next-generation packaging materials, with a spotlight on the "nano solder particles". These particles are notable for their potential to overcome challenges associated with miniaturization in electronic components.

This product is a semiconductor micro-packaging material that can be applied in the fields of 5G communications, mini/micro LEDs, and areas using traditional SMT (Surface Mount Technology) manufacturing techniques.

As semiconductor components shrink, there's a move towards using nano-grade particles in solder paste and conductive particles in ACF (Anisotropic Conductive Films). HighChem's newly developed "nano solder particles" address this trend, offering solutions to issues like oxidation and agglomeration caused by particle size reduction. HighChem is currently providing samples upon request, aiming to boost demand through their exhibition presence.


We also plan to exhibit other next-generation packaging materials.

Compound semiconductor substrate (wafer)
GaN substrate, SiC substrate, GaAs substrate, diamond substrate, etc.


HighChem is recognized for its import and export activities between Japan and China, especially in the electronic materials sector, leveraging its strengths in quality and cost. It has earned trust through years of reliable service. At the exhibition, HighChem will highlight semiconductor substrates like GaN, SiC, GaAs, and diamond substrates, showcasing their extensive production experience in the Japanese market. Additionally, a variety of semiconductor and electronic materials will be on display.
