Green Innovation: Jufeng Pressureless Silver Sintering Technology Leads a New Trend in Joining Materials

With the rapid development of high-precision fields such as electronic RF applications and electronic communications, the industry is placing higher requirements on joining materials.

Compared with traditional high-lead solder paste, high-lead solder wire and lead-free solder paste, Jufeng’s innovative pressureless silver sintering technology shows outstanding advantages in low-temperature processing, high-temperature service capability, thermal and electrical conductivity, and environmental protection. It brings both performance and green innovation to the industry.

High-Lead Solder Paste / High-Lead Solder Wire and Lead-Free Solder Paste: Technical Comparison

As traditional high-temperature joining materials, high-lead solder paste and high-lead solder wire are mainly composed of tin and lead. They offer several notable characteristics:

Environmental and Technical Limitations

However, high-lead solder paste and high-lead solder wire also face serious environmental challenges. In many countries, lead-containing materials have already been restricted or banned in manufacturing.

To solve environmental pollution problems, lead-free solder paste was developed. It contains no lead and meets environmental requirements. However, despite its environmental advantages, lead-free solder paste still faces technical challenges.

Sintering Technology Combines High Performance and Environmental Protection

Against this background, sintering technology has emerged as a revolutionary solution for the joining industry. Pressureless sintering is a process that uses temperature to bond micro- and nano-sized particles together while connecting adjacent surfaces.

Compared with traditional solder alloys, sintered silver demonstrates significant advantages in multiple aspects:

In addition, sintered silver leaves no residue after sintering and does not require cleaning, making it more suitable for efficient and environmentally conscious manufacturing.

Advantages of JUFENG Pressureless Silver Sintering Technology

JUFENG pressureless silver sintering technology inherits the advantages of sintering technology while showing its own technical breakthroughs and innovation in practical applications.

JUFENG sintered silver is compatible with multiple interfaces, including gold, silver and copper. It is also committed to green and environmentally friendly manufacturing, making it a comprehensive alternative to traditional high-lead solder materials.

EU RoHS Standard and Market Transition

It is worth noting that under the EU RoHS Restriction of Hazardous Substances standard, high-lead products are currently exempted when used as semiconductor chip attach materials.

However, this exemption may be removed in the future. Therefore, the market needs to transition as soon as possible to meet stricter environmental requirements. JUFENG sintered silver materials provide an ideal solution for this shift.
