High Temperature Solder Paste SACX0307

High temperature solder paste SACX0307 SACX0307(Sn99Ag0.3Cu0.7) is made with solder blenders, It is lead free, organic acid, rosin flux solder paste that provides users with the highest level of consistency performance. Its melting point is 227degree Celsius, high copper and low silver composition,it is high temperature solder paste, working temperature from120degree Celsius to 280 degree Celsius.Batch after batch, SAC0307 provides hours of stable stencil life, tack time and repeatable brick definition. SAC0307 robust printing characteristics result in consistent solder paste volume regardless of idle time, stencil life and print speed. The activator package in the SAC0307 is very aggressive and provides superior wetting to OSP coated and Immersion Silver boards. Generally used is type3 and type 4 powder.

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.

LF-02 SACX0307 solder paste recommended reflow soldering temperature profile

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.
