Flux chemically removes oxide film from
the to-be soldered metal surface, and the molten solder
surface, thereby exposing solderable metal surfaces.
Flux is therefore indispensable in all soldering processes,
including PC board and special metals. It must possess
the correct characteristics to meet specific application
requirements. From Senju Metal Industry's long experience,
we have developed various types of flux, including PC
board flux, all of which provide unrivaled performance.

* The procedure is
similar to chlorides and bromides test.
There are many types of flux, depending on the required
application and performance.
We supply a wide choice of fluxes including the resin
type and water soluble type to meet every needs.
