Gold-Tin Solder Paste

An80Sn20 solder powder with excellent sphericity, uniform particle size, and low oxygen content is combined with halogen-free flux to produce FH-280 series solder paste. FH-280 has a superior adhesion effect before soldering. Solvent volatilizes very slightly during soldering. In addition, the solder paste has outstanding wettability, anti-slump, anti-collapse and less residual performance. There is no solder ball formation during soldering. Moreover, FH-280 has high tensile strength, excellent corrosion resistance, high melting point, and extraordinary thermal creep performance. FH-280 is compatible with other precious metals and has excellent electrical and thermal conductivity. The product is suitable for the high-reliability packaging of semiconductors and microelectronic devices. It is applied to the high thermal conductivity packaging of high-power devicesdevices.

Recovery method: Don't open the bottle cap until the solder is close to room temperature. No more than two times of temperature return.

Recovery time: Generally, paste should be removed from refrigeration 2~3 hours before use. Actual time to reach thermal equilibrium will vary with container size.

Note: Do not open the bottle cap without sufficient "recovery" or shorten the recovery time by heating the paste.
Operating Environment: The best operating temperature and humidity are 20-25°C and 40-60%RH, respectively. Reflow soldering in a nitrogen atmosphere is recommended.
