NC-559-ASM solder paste is a small-sized and easy-to-carry product that weighs about 100 grams/3.5 ounces. It has a granularity of 28 (um) and viscosity of 180 (Pa·S). The paste provides several advantages, including preventing oxidation during high-temperature soldering and reducing the surface tension of the material for better quality soldering. Additionally, the tin in the paste has a fast running speed, low smoke generation, and high residual insulation resistance, making it a good insulator. The rosin in the paste is also an excellent insulator that does not conduct electricity under dry conditions. The flux has anti-oxidation properties that protect the soldering iron tip of the gold-copper alloy matrix. The semi-solid flux is not easy to pour, making it convenient to use. This product is widely applicable in various fields, such as clocks and watches, precision parts, stainless steel crafts, tableware, mobile communications, digital products, air conditioning and refrigerator refrigeration equipment, glasses, knives, car radiators, and various PCB boards.
