Sn99.3Cu0.7 alloy is one of the most used solders available at a very low cost. It entirely free of Pb and avails the outstanding soldering performance with varieties of flux technologies. For different surface, finishes deliver a good wettability.
Sn99.3Cu0.7 is the best fit for dipping, waves and many more soldering applications. We can leverage this alloy in the shape of wire for handling cases like solder pot auto-feed. A solder pot requires 260 to 270°C for board designs and soldering applications.
We will recommend the top-up solder as Sn99.95 with Cu% more or equal to 0.7.
Sn99.3Cu0.7 is present in bars with a ratio of 20 kg per box. You can contact our sales team to elaborate on metal forms requirements as per need.
HEALTH & SAFETY
You can go through MSDS to understand safety and handling instructions.
You must keep the solder bar in a dry, non-corrosive and dry environment. To avoid environment exposure, we need to wrap the solder bar when it’s not in the use.
We can keep Sn99.3Cu0.7 for up to five years. But we must ensure all the storage conditions to be fulfilled. You can observe the reduced surface shininess with dull gray or light yellow shade after a few times. Anyway, it doesn’t affect product functionality.
