… and will prevent to spread there, where you don´t want to. Fluxes in pen Stannol series Mini Fluxer belong to the invaluable helpers of every electro-technician.
How could I work without a flux so far? That´s a probable question of probably everyone, who once tried action of a solder flux. In a common wire solder, there´s some amount of a flux, usually sufficient for one-time soldering of a given joint, if the components to be soldered are clean and oxides-free. However, we know well a case, when we use for example an older PCB, or an older component with slightly oxidized leads and suddenly it´s much harder to reach an acceptable joint. Similar situation happens at an exchange of a component or any service action, when a solder tends to oxidize on a surface and create various bad-looking creatures, which are quite far from a professional joint. Fortunately, there´s a flux here …
In general, fluxes act in a manner, that a solder is as if „more movable“ after application. It is mainly thanks to the protection against oxidation, change of surface tension and other influences. As a result it means, that a solder spreads well on metals and joints with a given material (what we naturally want) and on the non-metal substances (PCB) is a solder repelled as if on an oily surface.
At an automated „all-surface“ soldering, fluxes are usually applied by wetting (foam) or by spraying. At development and servicing smaller packages are much more practical, for example in a form of a pen. Two novelties in our offer also belong to this category:
● Stannol MINI-FLUXER X32-10i – halogen free, activated „No clean“ flux, practically residue-free, vey tolerant to various working conditions. Minimum amount of electrically safe transparent residues with a high insulation resistance enables its usage even at visible places and at production of highly reliable devices, including solar panels. Significantly eliminates build-up of bridges, that´s why it´s very suitable even for manual soldering of fine-pitch components.
