Flux cored solder wire
For Aluminum wire soldering K4-C601-3
Comply to aluminum wire
Solderable by iron to aluminum wire, used such as in the HDD of the actuator.
Solderable to aluminum
●Soldering test to aluminum
Solderable to aluminum
Put solder wire on aluminum board and heat by 270℃
Prevent galvanic corrosion
Additive elements achieve high soldering reliability and prevent the galvanic corrosion that occurs between the aluminum material and solder.
High soldering reliability
●Electrolytic corrosion test
Measure the time until the solder delamination occurs, stored in 40℃ of artificial seawater, after soldering the two aluminum plates
Good water washability
Apply water-soluble base material instead of rosin.The residue after soldering is possible to wash away easily with water.
Good water washability
●Ionic residue test
The flux residue is possible to clean with water
