BK-220 is a type of soldering flux used for bonding electronic components and printed circuit boards. This type of resin is highly effective in preventing oxidation and corrosion in solder joints. BK-220 rosin is made from high-quality materials, making it highly durable and heat resistant. In addition, its unique formulation provides it with excellent flowability, making it easy to apply. The resin is compatible with a wide range of metals, including copper, bronze, nickel, and silver. Its adhesion ability is excellent, which means it easily adheres to the surfaces of components and printed circuit boards. Acid value (KOH/g) > 165mg Softening point < 75ºC
