Flux cored solder wire

Less spattering type MYK series
Very few spattering

Select suitable flux base material for higher melting point alloy.Very few flux spattering can achieve high performance soldering.

Very few spattering

●Flux spattering test by using soldering iron robot

Can apply with LASER soldering with low Ag

Selected materials suitable for rapid light heating achieves high workability. Good wettability with low Ag alloy can help to reduce cost.

Can apply with LASER soldering with low Ag

●Confirmation of wettability with LASER soldering
