LOW-TEMPERATURE SOLDER PASTE

Low-temperature solder pastes are used in electronics production where the use of solder pastes based on SAC alloys is impossible due to the temperature sensitiveness of the components or printed circuit boards.

The most commonly used low-temperature solder paste is tin and bismuth-based. The advantage of this alloy is that it allows for the lowest soldering temperature. Its disadvantage is that the resulting solder connections are shock-sensitive in contrast to the SAC305 alloy.
