Product Description
Sn42/Bi58 is a low melting temperature alloy composed of 42% tin, 58% bismuth. Low temperature solders require a lower peak reflow temperature than other lead-free solder alloys reducing energy consumption and component-warpage related defects such as NWO (non-wet opens).
Sn42/Bi58 alloy is available with specially formulated fluxes to ensure solder joint integrity and high electrochemical performance, even at reduced reflow temperatures.
Application Use
- Lead-free low melt alloy
- Low temperature solder paste reduces overall reflow profile temperature significantly lower than SAC305 (217-219℃)
- Reduces NOW/HiP defects on temperature sensitive components
- Good wetting performance required for quick, post-assembly attachments
