Features
1. Lead-free soldering flux is suitable for foaming, spraying and dip soldering.
2. LC-700 series liquid flux has four models-LC-700, LC-701, LC-702 and LC-HF700. All four pass silver chromate test, copper mirror test and copper plate corrosion test.
3. It is characteristic of little smell, optimized mechanism property, less residues and high impedance.
4. Besides, this lead-free soldering flux conforms to the demands of ROHS and REACH.
5. The surface insulation resistance is beyond 11010 and halogen content is less than 0.01 % excluding LC-HF700 that has no halogen at all.
6. It is widely suitable for lead-free automatic wave soldering and hand dip welding. Generally, the flux is extensively applied in dual and multi-line circuit board and PCB boards of electronic, computer, telecommunication and household appliance.
