Characteristics of Tin Lead Solder Bar 63/37

1. The bar solder Sn63Pb37 has the eutectic melting point which means the liquidus & solidus temperature are same. 

2. This is the lowest melting point of all tin lead solders, it's to be used for where temperature limit is crucial.

3. Good wetting and fluidity, good bonding of soldering point.

4. Very low dross.

5. Compatible to major brands of flux.

6. Use in high tech electronic applications where lower surface tension and hole filling ability is essential

Storage and Handling of Tin Lead Solder Bar 63/37

1. Store the solder bars in dry & non-corrosive place.

2. The solder bar has an indefinite shelf life when stored in a dry, non-corrosive environment. The surface may lose its shine and appear a dull shade of gray. This is a surface phenomenon and is not detrimental to product functionality.

3. Make sure you select a proper flux to go with the solder bar because all bars are without flux.

4. Read MSDS & TDS of solder bar 63/37 (Sn63Pb37) before soldering
