Solder Paste
COSMO series
General Use (Room Temperature Storage Compatible)
NP303-COSMO-ZQ-C
Solder Paste Compatible with Room Temperature Storage
Even delivery and storage at room temperature, our solder paste can remain in stable quality
without deterioration unlike the previous model. It become easier to handle. (JIS AA type Sn-3.0Ag-0.5Cu)
6 Month Guarantee at 35℃
Storage Period Change with Viscosity at 35℃ and 50℃ Storage Temperature
①Since viscosity and characteristics can maintain as initial level even after 6 month at 35℃ it’s able to storage 6months at room temperature.
②Since viscosity and characteristics can maintain as initial level even after 1 month under 50℃ it’s able to transport at room temperature.
