Low Temperature Curing Solder Paste

ACS-Bi3500A

ACS-Bi5000

ACS-Bi3500A is a lead-free solder paste formualted with SnBiAg1 solder powder, utilizing a non-eutectic low-temperature alloy with a melting point lower than that of SAC305. The flux system complies with ROL0 classification under JIS standards.

ACS-Bi5000 is a solder paste composed of bismuth specifically developed for low-temperature reflow soldering applications.
By utilizing Sn-Bi solder powder, a melting point of approximately 138 °C is achieved.

  • Non-eutectic and low temperature solder alloy suitable for SMT assembly process with temperature sensitive substrates and components.
  • Lower reflow peak temperature reduces energy consumption in SMT process.
  • Reduces component warpage and other defects such as HiP and NWO defects with lower temperature used.
  • Good soldering performance.
  • Low temperature lead-free solder alloy suitable for SMT assembly process with temperature sensitive substrates and components.
  • Lower reflow peak temperature reduces energy consumption in SMT process.
  • Good soldering performance.
