Ultra-Fine Printing 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".

Products Description

Product Documentation

Printing solder paste is a kind of solder paste that is printed on the substrate pads through the stencil apertures. Printing solder paste is widely used in the SMT and semiconductor packaging processes. Printing solder paste is the most prevalent kind of solder paste in electronic assembly. Extraordinary printing solder paste requires excellent solder release performance, long stencil life, superior anti-slump performance, and outstanding thixotropic performance.


Ultra-Fine Printing Solder Paste


The specific surface area of the solder alloy is large as ultra-fine solder pastes (T6 and above) have small particle sizes. A large surface area of the solder alloy leads to a great increase of contact area with the air, which makes it easier to be oxidized. With the progress of printing, the solder paste with inappropriate control of oxygen content will be continuously oxidized in the air, resulting in dramatic changes in viscosity and thixotropy, thus reducing the stability and reliability of the process.

One of the keys to controlling the quality of ultra-fine solder paste is to reasonably control the oxygen content of the ultra-fine solder powder in solder paste, thereby ensuring the process stability of the printing solder paste.

1、Storage and Recovery Instruction: Solder paste is normally stored in a refrigerator with -5~10℃. When solder paste is taken out of the cold box,its temperature is much lower than room temperature. If use without the recovery process varies damage may be caused to the paste. Opening the cap of sealing may cause water vapor in the air to condense on the paste. If this occurs, later in the reflow furnace (temperature over 150 ℃ ), water would vaporize due to strong heat.This may lead to solder explosion and damage the chip.

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

3、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.

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.
