無鉛(エバソル)

Solder paste (bottle)

Transparent residue for LED soldering type 8860 series
No color flux residue

Apply colorless base material suppress the coloring of the residue.Beautiful soldering appearance persists without discoloration long time after SMT.

No color flux residue achieve good appearance

●Comparison of residues after reflow

Ensure high quality soldering in illumination equipment such as LEC lamps

High insulation resistance at high temperatures

Optimization of the type and amount of activator keep the insulative even at high temperatures.Malfunction of the LED lighting equipment is prevented under harsh environment.

High insulative even at high temperature

●Insulation resistance test at 85℃ and 120℃

Stable insulation resistance
