Solder Paste
COSMO series
High Strength (Room Temperature Storage Compatible)
SAB433-COSMO-ZQ-C
Improved Joint Reliability
Suppressed crack growth by adding Bi and Sb.
Furthermore, while maintaining the melting characteristics due to the effect of the additive elements
Improved joint reliability compared to SAC305.
Even delivery and storage under normal temperature.
