Laser re-balling
|
Technical Concept |
|
Laser re-balling system is a semi-automatic solder ball placement reflow/rework machine designed for small volume production, prototyping, and research and development. The maximum throughput is 5 balls per second. The ball diameters range from 100μm to 350μm. It is an ideal tool for BGA and CSP rework jobs during electrical characterization or final tests. |
