Features: Advanced thermal insulation technology, long-lasting adhesion, not easy to dry, and the adhesion-time is more than 48 hours. The residue-is colorless and-transparent, does not affect the detection, no-washing and excellent cleaning performance. The product has good wettability, strong resistance to dryness, a relatively long shelf life at room temperature, and a wide-range of applications. Solder tin-paste is a new type of solder material that comes with-SMT. Solder paste is a complex system that is made of a paste of solder powder, flux, and other additives. At the normal temperature, the solder tin-paste has a certain viscosity, and the electronic component can be initially adhered to a predetermined position. Specifications: Material:Tin Size:Approx.9.5x2x2cm/3.74x0.78x0.78inch Color:Silver Instructions: After the solder paste is opened, it is recommended-to use it within 24 hours at room temperature. Placed in-the air for long-time, the solder paste will become a tin-block due to moisture absorption. To wipe the wrong-substrate, it is recommended-to use industrial alcohol-or industrial cleaner.
