clean-free flux

 Technical Data Sheet

DESCRIPTION

1. TF328 is clean-free flux. It is applied in a wide range. In spraying or foaming wave-soldering, its performance is superb. The activity of the flux is specially designed, especially fit for leadless welding. Even for PCB with common weldability, its performance for welding is still good. The moderate solid content in the flux and the internal activity ensures the least residues after the welding of PCB. In addition, the surface of PCB is dry and clean. If there are no special requirements, the cleaning procedure can be saved to reduce the production cost of manufacturers.
2.  Another feature of TF 328 is that it has a high insulation resistance after being welded. This can ensure the reliable performance of PCB.
3.  As to TF328, it has a wide range of technical data. Thus it can be applied in different environment, equipment and practical techniques. 

FEATURES

1.  Smooth and polished surface of weld spot
2. High wettability
3. Non-corrosiveness
4. Less residues and clean-free after being welded
5. Comply with IPC J-STD-004
6. High insulation resistance of surface

HANDLING

1. Expiration date for TF-88-7 in air-tight condition is 1 year. Do not refrigerate it.
2. Keep away from fire. Avoid direct sunlight or high heat.
3. Do not pack used flux and new flux together. Keep container air-tight.
4. If flux is reserved for a long time, the user should calculate its proportion before using it, and adjust the proportion to normal by adding diluent to it.

FLUX APPLICATION

PROCESS CONTROL

The use of flux is very important during the operation, which can keep the stability of the compositions of the flux. The accurate control of wave-soldering not only guarantees constant soldering effect, but also reduces the residue after soldering to minimum, thus eradicating the disturbance to soldering probe.
