They are bar-shape and wire-shape products made from solder alloy. Bar solder is used for flow soldering. And solder wire is used for auto-supplying to solder bath, or soldering by solder iron with flux.

This is solder wire which includes resin flux at its center. This product can be used for iron soldering as it is, without flux.

This is extremely fine flux cored solder wire. It is finished from hundreds of to tens of microns with high diameter accuracy. It is used for micro soldering, like narrow pitch terminal.

This is paste type solder made by mixing tens of micron diameter solder powder with high-viscosity flux. This product is used for reflow soldering, being supplied by printing or from syringe.

This is a product like wire and ribbon shape, made from solder alloy with high accuracy. It is used for sealing and fuse element other than micro soldering.
