The solder matters, it is an undisputable fact confirmed daily in a development and production of electronics. Hand soldering of prototypes, automated machine soldering, soldering of small SMT components or on the in contrast soldering of big joints of massive connectors, rework, … all that wants a solder optimized for a given usage.
As we know, features of a solder wire are determined by an alloy itself (PbSn xx, SnAg xx, …) but in a considerable extent also a flux used. A flux has a big influence mainly on a soldering process, spreading of solder (often even on partially oxidized surfaces), spitting at hand soldering, etc. That´s why despite of often similar specification (according to datasheets), it is still possible to see considerable differences among solders after all. Besides the most important parameters like composition of alloy and flux properties, some features (like spitting and solder spreading) can be really evaluated only at working with a given type.
Over 130-years experience of German company Stannol give a guarantee, that in their portfolio can be found a type suitable even for your work. In a Stannol catalogue can be found favourite “universal” types suitable for the most types of works in electronics and electrotechnics (for example HS10, HF32, Kristall 400) but also specialized types suitable even for soldering of poorly solderable surfaces.
The principle of Stannol products marking is in it, that they are marked by a flux type (HS10, HF32,…) and by an alloy used (Snxx, SnPb,…). A solder wire is available in many combinations flux / alloy , that´s why it is suitable look at their properties in detail and then to choose a suitable type. On stock we keep the most favorite types with fluxes HS10, HF32 or 2630, suitable for majority of joints.
