Choice of Laser Sources for Micromachining Apps

To date majority of the micromachining applications have been addressed with the lamp pumped pulsed Nd:YAG laser. However, the increasing complexity of microelectronics/ engineering devices and the requirement for higher yields and automated production systems place stringent demands on the micromachining techniques. This has led to development of new laser sources fiber and dick lasers etc. These lasers with diffraction limited beam quality offer many advantages such as small spot size, high power density, enhanced processing speeds, reduced heat affected zone for a range of micromachining applications.
