Features: Premium rosin flux enhances soldering quality by effectively removing oxidation and ensuring clean surfaces for reliable electrical connection on circuit boards. This low corrosion formula reduces surfaces tension for better solder wetting, and leaves no conductive residues to prevent short circuits. Ideal for electronics engineers, DIYer enthusiasts, and professional working with delicate PCB assemblies requiring precise soldering. Perfect for repairing circuit boards, assembling electronic components, or crafting durability solder joints in workshops and manufacturing environment. The iron tin container preserves flux potency while its none conductive, high impedance properties ensure safe application across industrial and hobbyist soldering projects. Specifications: Size: Approx.33x13mm/1.3x0.51inch Quantity:1pcs/3pcs/5pcs Package Includes: 1pcs/3pcs/5pcs Soldering Flux note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you donot mind befores you order. 2.Due to the differences between different monitors, the picture may not reflect the actual coloring of the item. Thanks for your understandings.
