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".

ULTRA-FINE SOLDER PASTE

Low-temperature solder paste has an alloy melting point lower than 180oC, and the peak reflow temperature should not be greater than 200oC. It is used in the second reflow of the secondary reflow process, and it can be used for the packaging of non-heat-resistant and heat-dissipating components. The low-temperature solder powder is synthesized based on bismuth elements by adding other metal powders.

Description

Fitech's tin-bismuth-silver alloy solder powder with excellent sphericity, uniform particle size, and low oxygen content is mixed with excellent zero-halogen flux to prepare FTP-574 series low-temperature solder paste. Solvent volatilizes very slightly during soldering. There is no solder ball formation and only a small amount of residue forms after soldering. Moreover, the product has outstanding wettability, and the solder joints generated are plump and bright. It is effective for low-temperature component mounting.

Instructions

1. Warming Instruction: Solder paste needs to be refrigerated, and the preferred temperature is 0-10°C. When the solder paste is taken out 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 increases vaporizatipn of water, which may 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 by using heat equipment.

5. 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.

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.

FACA-138D series is a low-temperature metallurgical-bonding halogen-free anisotropic conductive paste (ACP). The main alloy component of FACA-138D is SnBiAg0.4. Fitech classifies solder powders into T8 powder (2-8um), T9 powder (1-5um), and T10 powder (1-3um) based on particle sizes. Solder powder and epoxy-based flux are combined to produce a low-temperature conductive paste.


02
Features

1. The conductive filler has uniform particle size, and FACA-138D has outstanding dispersion performance;

2. After hot-pressing solidification, the bonding of insulated materials increases soldering reliability;

3. There is no solvent volatilization during the hot-pressing curing process;
4. The hot-pressing temperature is low, and the solder powder melts and metallurgically connects with the pad, enhancing the 
bonding strength;

5. FACA-138D is an extraordinary anisotropic conductive solder that is longitudinal conductive and non-conductive in the transverse direction.
