ULTRA-FINE SOLDER PASTE

Ultra-fine solder paste

T6, T7, T8, T9, and T10 solder powder are called ultra-fine solder powder because of their small particle sizes. Solder paste consisting of T6 to T10 solder powders is called ultra-fine solder paste. With the continuous development of the microelectronics and semiconductor industry, the chip size is getting smaller while the packaging density is getting higher. It's hard to meet the requirements of microelectronics and semiconductor packaging with traditional solder paste products of T4 and above. Currently, the solder paste used in packaging is increasingly being "ultra micronized".



Fitech is the world's leading supplier of ultra-fine solder powder and solder paste. Fitech has world-leading production lines of tin-based ultra-fine solder powder. Fitech's Tin-based ultra-fine solder powder products have the advantages of high purity, narrow particle size distribution, excellent sphericity, and outstanding quality stability. Fitech is currently the only packaging material supplier in the world that can produce T2-T10  electronic-grade solders.

Description

SnSb10 alloy solder powder with excellent sphericity, uniform particle size, and low oxygen content is mixed with no-clean flux to produce FTD-901 series solder paste based on metallurgical method and chemical structure. The solder paste has a superior adhesion effect before soldering. Solvent volatilizes very slightly during soldering. Moreover, FTD-901 has outstanding wettability, anti-slump, and residue reduction properties. It is developed to meet the market demand for heat-resistant microelectronic assembly and precision soldering. The product has extraordinary heat resistance and heat dissipation abilities. It also improves the voiding of solder joints 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 40-50%RH, respectively. Reflow soldering in a nitrogen atmosphere is recommended.



Description

Instructions

1. Warming Instruction: Solder paste needs to be refrigerated, and the preferred temperature is 0-10°C. When taking out the solder paste  from the cold box, its temperature is much lower than the room temperature. If the bottle cap is opened without rewarming, the water vapor in the air will easily condense and adhere to the solder paste.The high temperature exceeding 150°C during soldering rapidly increases vaporizatipn of water, which is easy to cause the phenomenon of "exploding solder" to produce solder balls and even damage the components.

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

3. 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.

4. Note: Do not open the bottle cap without sufficient rewarming or shorten the rewarming time by using heat sources.

5. 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.

6. Operating Time

① Continuous printing time: When adding solder paste continuously: 8 hours; In case of discontinuous addition of solder paste: 4 hours; ② Please add solder paste before the solder paste on the board is almost one third (rolling diameter: 10mm or less); ③ Please keep the solder paste on the plate within 3 hours; ④ If printing is interrupted for more than 30 minutes, please clean the stencil. ⑤ Dwell time after printing: After the solder paste is printed, the components should be mounted as soon as possible and the soldering should be completed when passing the oven to avoid drying out the surface of the solder paste due to long storage, which will affect the component mounting and soldering effects. Generally, the recommended dwell time of solder paste is no more than 4 hours, while the low temperature bismuth-containing solder paste does not exceed 2 hours. If the printing is interrupted for more than 30 minutes or is temporarily interrupted, the printing template needs to be cleaned. It can continue to work after 1-2 trial printing. The solder paste attached to narrow space of the opening (≤0.4mm) and the opening of the stencil will gradually dry, which will degenerate the adhesive ability.
