Medium Temperature Laser Solder Paste

Fitech produces SAC305 solder powder with excellent sphericity, uniform particle size, and low oxygen content, and it is mixed with halogen-free flux to prepare FTD-305 series solder paste. The solder paste has superior adhesion before soldering. Solvent volatilizes very slightly during soldering. Moreover, FTD-305  has outstanding wettability, anti-slump,anti-collapse and less residual performance.There is no solder ball formation during soldering. The product is an ideal solder for micro-bump ultra-fine-pitch packaging.

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 40-50%RH, respectively. Reflow soldering in a nitrogen atmosphere is recommended.
