Feature: 1. DIFFERENT SIZE: There are 12 different sizes for you to choose from, from 0.2mm to 0.889mm, to meet your needs. 2. SMALL BUT USEFUL: These solder balls are small but transmit electrical signals and are very useful for your soldering work. 3. TIN MATERIAL: These solder balls will not be oxidized by air at room temperature, and the oxidation will be accelerated under heating, which is very suitable for soldering. 4. SUFFICIENT QUANTITY: There are 10PCS bottles containing approximately 25,000 solder balls and 2PCS bottles containing 10,000 solder balls for your basic soldering needs. 5. MAIN APPLICATION: These solder balls are used for the connection of semiconductor chips, circuit modules and PCB boards.
