Japan Unix can help customers choose the laser type most suitable to their board patterns and components. For example, if the pad has an ellipse shape, customers should expose it with the oval type. Also, if the through-hole has black resin or other components on the back, customers should use the ring type to prevent the laser burning it.
Laser shapes available in circle & square types
Laser shapes in a variety of types, including circle, oval, square, ring, oval ring and twin, have been released by Japan Unix. A beam-splitting technology provides a twin-spot laser, which enables the simultaneous soldering of two joints.
