The “Invisible Hero” Behind 5G Signals: How Betely Conductive Silver Paste Enables More Stable Antenna and Base Station Connections

When you stream videos or play online games on a 5G smartphone, the fast and stable signal experience depends heavily on mobile phone antennas and base station filters — both of which rely on conductive silver paste.

To meet the demands of these two critical application scenarios, Betely has developed specialized conductive silver paste solutions that help ensure stable and reliable 5G signal transmission.

Two Core Product Series for Mobile Devices and Base Stations

Low-Temperature Curing Antenna Silver Paste (Mobile Applications)

Today’s smartphone antennas are commonly integrated into plastic back covers or middle frames. Since these materials are not resistant to high temperatures, the conductive silver paste used for antennas must support low-temperature curing processes.

Betely’s low-temperature curing silver paste products have already been mass-produced and applied in smartphones from major brands such as Huawei, OPPO, Xiaomi, and Samsung, meeting the low-temperature processing requirements of mobile antenna manufacturing.

5G Base Station Filter Silver Paste (Base Station Applications)

The core substrates used in base station antennas and filters are primarily ceramic materials, which require high-temperature sintering during production. The silver paste must be co-sintered with the ceramic substrate to form an integrated conductive structure.

SF-3100

• Sintering temperature: 200–250°C

• Suitable for conventional ceramic substrates

SF-3200

• Sintering temperature: 450°C

• Designed for high-performance ceramic components

Excellent Solderability

• Supports soldering within 2 seconds at 260–300°C

• Tin coverage area ≥90%

• Compatible with electronic component mounting processes

  
  

Core Product Value and Reliability

Critical Material for LTCC Processes

Betely conductive silver paste serves as a key conductive material in LTCC (Low Temperature Co-fired Ceramic) technology, supporting the precision manufacturing of 5G base station filters.

Strong Environmental Resistance

The products have passed multiple stringent reliability tests and can withstand harsh outdoor operating conditions, including:

• Wind and sun exposure

• Large temperature fluctuations

• Long-term environmental stress

This ensures stable long-term performance for outdoor 5G base station applications.
