Connecting the "Core" World
Solder Balls / Paste
With the development of flip-chip technology, α particles-induced soft errors have gradually increased. Under current packaging technologies and conditions, the use of low-α solder is a cost-effective measure to reduce the incidence of soft errors. The LA tin-based solder products developed by our company are prepared with low-α raw materials, which can effectively reduce the incidence of soft errors.
We have the XIA UltraLo-1800 ultra-low background α counter, which can quickly detect the emission level of α particles.
Low α rating
Low class α（LA） (<0.01cph/cm2)
Very low class α(ULA) (<0.002 cph/cm2)
Ultra-low class α (SULA)(<0.001 cph/cm2)

Nano Ag-Cu Solder Paste
At present, our company has developed nano Ag-Cu supersolid solution alloy, which has stronger oxidation resistance, and the same new generation of nano Ag-Cu supersolid solution alloy adopts bimetal, which reduces the amount of silver and reduces costs compared to nano silver. The solder paste prepared by a new generation of nano-Ag-Cu supersolid solution alloy not only overcomes the problem of high cost of traditional nano-silver and the problem of easy oxidation of nano-copper, but also solves the problem of mixing and storage of nano-copper-silver mechanical hybrid solder paste, and has a wider range of applications.
Realize low-temperature welding and high-temperature service★
The bonding strength of the current sintering process exceeds that of nano-silver paste
Reduce the proportion of precious metals and reduce costs
Inhibition of electrochemical migration of Ag is 5 times that of nano-silver paste★
Excellent thermal and electrical conductivity
Ag-Cu supersolid solution nanoparticles have better oxidation resistance and chemical composition stability than Ag@Cu nanoparticles
Strengthens Structural Paste
This product is a homogeneous blend of proprietary flux paste, alloy powder and nanometal powder. The use process of nanometal and solder powder forms composite filler, which improves the thermodynamic and mechanical properties of the solder joint due to the dispersion strengthening of the nano-second phase particles. At the same time, a high-performance thixotropic agent is added to the system, which has superior rheological characteristics, is suitable for surface mount processes, and can also be used for spot coating in addition to printing processes.
This product meets EU RoHS 2.0 and halogen-free requirements and supports no-clean.
Multiple rewelding without collapse;
High stability after molding;
Can withstand short-term high temperature shock

Printing Solder Paste
QW-868 Printing Solder Paste is a continuous printing stable no-wash type solder paste. This product can be applied to electronic components, connectors, integrated circuits and other product connections.
This product is stable continuous printing, no tailing, no scattering points.
Low Temperature Series Products
Low-temperature solder metal includes low-temperature solder balls, low-temperature solder paste, low-temperature solid core tin wire, and low-temperature rosin core tin wire. In the case of low-temperature bismuth tin-bismuth paste, the soldering process is the same as that of standard electronic assembly technology using surface mount technology (SMT), and the operating temperature of low-temperature bismuth tin bismuth paste is 70°C lower than that of traditional filler metal, only 180°C. Since the soldering temperature of low-temperature tin-bismuth solder paste drops from 250 °C to 180 °C, the thermal stress in the soldering process is reduced, and the warpage of the printed circuit board is effectively reduced.
Redevelopment of traditional products to facilitate new process manufacturing
Low temperature connection scheme
Connecting the industry of the future
Through years of technology research and development, the company adopts unique molding technology to break through the low-temperature tin-bismuth solder wire forming process of rosin core. This process overcomes the problem of brittleness of tin bismuth tin wire and provides a solution for tin bismuth tin wire in batch automation applications
Laser welding special
Pre-coating technology refers to the presetting of flux such as rosin on the surface of traditional solder products such as solder balls and solder wires, so as to eliminate the flux/paste process during use, achieve process optimization, and reduce the occurrence of defects such as tin beads and frying tin. At present, it is mainly used in laser welding, manual welding and other scenarios.
