無 鉛 銲 錫 線
Lead Free Solder Wire |
Features
| |
- Continous casting procsss ensure the zero defect in extrusion cylinder
- Excellent drawing process could produce solder wire with very small diameter
- Scientific flux composition could ensure the good solderability
- Non-corrosive, no unpleasant odor, minimized solder flus spattering
- Transparent rosin residue of shiny solder spots
|
Process notes for Pb-free iron soldering:
| |
- The temperature of iron tip should be 370-400°C
- The iron power should be 60-80W
- The iron should have good heat-restore performance
- Replacement frequency of iron tip will be higher than Pb-contained application
