Brief Description for LF-02 SACX0307 solder paste
Solder paste is prepared by kneading solder powder and solder flux and is used for surface mounting PC boards. BBIEN’S solder paste is a combination of solder powder without oxidation in a uniform particle size and flux with excellent chemical stability.
BBIEN‘s Sn99Ag0.3Cu0.7 solder paste is a no-clean tacky soldering flux formula that possesses a high activity level, allowing it to solder nickel surfaces. The robust wetting action of this solder paste will allow OSP treated copper, as well as heavily oxidized copper, surfaces to exhibit good soldering properties, even after 2 or 3 thermal cycles. Following reflow, SAC0307 will leave aesthetically pleasing clear residues on the assembly. Sn99Ag0.3Cu0.7 is designed for a high range of temperature and humidity conditions.

Using notes:
Storage, handling and shelf life In general,LF-02 SACX0307 solder paste is stored in 2 ℃ -8 ℃ temperature refrigeration, Shelf life: six months (starting from the date of manufacture), goods should follow the FIFO principle.
Open the package using the solder paste is necessary before fully warmed to room temperature (recommended for 4 hours); return temperature for 48 hours in the retention period, after opening a period of 12 hours, stay in the solder paste reflow PCB board to have pre- idle time is 100 ± 20 minutes.
Cold storage may cause the separation of components within the solder paste, solder paste is stirred well before use 3 to 5 minutes to re-mix. (Recommended: automatically stir 3 ± 0.5 minutes, hand-mixing 5 ± 1 minute, mixer speed: revolution 400rpm, rotation 100rpm)
Do not use the leftover solder paste mixed with the new packaging in the same bottle. Without the use of solder paste should be re-sealed, when the cap can not be sealed very well replace the cap when the sealing liner to ensure that as much as possible.
