Sparkle Ball
Solder Ball
Sparkle Balls are very small spheres of high-purity solder for micro soldering system. The most important advantages of solder balls are their very clean surfaces and exact solder quantity control. Solder balls are packed in argon gas for delivery to the user. A wide range of solder types including low and high temperature alloys can be produced as Sparkle Ball.
