Coherent Inc has introduced a new, higher power Paladin laser designed for high-throughput Laser Direct Imaging (LDI) and other advanced microelectronics applications. The new Paladin Advanced 355 24000 is a mode-locked, diode-pumped, solid-state laser that delivers over 24W (at 80 MHz) of output power at 355 nm. The Paladin family of lasers have an enviable reputation for superior reliability and performance and this new model continues that tradition by offering industry leading specifications, including a high quality, TEM00 beam (M²<1.2), excellent beam pointing stability (<20 μrad/°C), superior long-term power stability (<±2%), and low noise characteristics (<1% rms from 10 Hz to 2 MHz). Furthermore, this new 24W Paladin laser offers lower cost per watt than any previous model, thus reducing process costs, as well as improving throughput.
With over 1500 units currently in field operation, the Paladin series of lasers is well established as the market leader in Laser Direct Imaging
which enables the production of multi layer printed circuit boards without the complexity and registration issues of using traditional, film-based artwork. This technology has become increasingly indispensable as microelectronic devices have decreased in size. This new, higher power Paladin enables increased throughput in the digital patterning of the any-layer HDI PCBs now widely employed in the fabrication of these miniaturized devices, such as smartphones and tablet PCs. These lasers also service other applications in microelectronics fabrication, such as flat panel display manufacturing, solar cell production and bioinstrumentation. With models now available from 2W to 24W, system builders can always find a Paladin laser that is well matched to their application needs in terms of output characteristics and cost.
