LEAD-FREE SOLDER PASTE

Product's Details


Fitech produced lead-free solder paste under the idea of "lead-free electronics" which refers to the solder paste that the total concentration of toxic and harmful substances including mercury (Hg), cadmium (Cd), hexavalent chromium (Cr), lead (Pb), polybrominated biphenyl (PBB), polybrominated diphenyl ether (PBDE)) should not exceed 1000ppm. Lead-free solder paste should have outstanding wettability, solderability, electrical conductivity, and thermal conductivity. Moreover, it should have extraordinary reliability, compatibility, and economic benefit.

Lead-free solder pastes developed for different scenarios include the SAC305 series, tin-bismuth-silver series, lead-free silver-free series, high-temperature lead-free series, low-temperature high-reliability series, and gold-tin solder paste. All products have been widely used in microelectronics and semiconductor packaging.

Description

SnSb10 alloy solder powder with excellent sphericity, uniform particle size, and low oxygen content is mixed with no-clean flux to produce FTJ-901 series solder paste based on metallurgical method and chemical structure. The solder paste has a superior adhesion effect before soldering and less solvent volatilization during soldering. Moreover, the solder paste has excellent wettability, anti-slump, and residue reduction properties. It is developed to meet the marketing demand for heat-resistant microelectronic device assembly and precision soldering. The product has an extraordinary heat resistance and heat dissipation. It also improves voiding behavior and the strength and conductivity of intermetallic compounds.

Instructions

Warming Method: The sealed solder paste should rewarm to room temperature naturally; Rewarm no more than twice.

Warming Time: Return to warm for 2 to 3 hours at room temperature. The actual time required to reach thermal equilibrium varies by vessel size.

Note: Do not open the bottle cap without sufficient rewarming or shorten the rewarming time by using heating equipment.

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.



Description

FSA-901 series epoxy solder paste is composed of high-temperature Sn90Sb10 solder powder and halogen-free flux. Only a tiny amount of solvent evaporates during the soldering and solidification process. There is no solder ball formation after soldering. The solder powder melts and shrinks, and the solder joints are metallurgical connections, which are equivalent to the soldering effect of solder paste. FSA-901 epoxy solder paste is unnecessary to clean. The solder residue becomes thermosetting adhesive to reinforce the solder joints and enhance the anti-corrosion and insulation performance. The product is excellent for high-temperature soldering.
