Diode-pumped Laser suits silicon micromachining applications.
Press Release Summary:
AVIA(TM) 532-45 diode-pumped, solid state laser provides 45 W of average power at 532 Nm in single mode output beam (M2 less than 1.3). PulseEQ(TM) feature delivers constant pulse energy over time, even with varying repetition rates, while ThermEQ(TM) ensures uniform pulse energy when operated in burst mode. Applications include singulation of QFN, FBGA, µSD (MMC), and direct chip attach type of packages, as well as edge isolation of crystalline devices, and P2 and P3 scribing of thin film cells.
Original Press Release:
Coherent Single Mode Green Laser Sets Power Record for High Throughput Silicon Micromachining
Superior Reliability & Performance
Santa Clara, Calif., November 6, 2008 - The new AVIA(TM) 532-45 from Coherent, Inc. (Santa Clara, CA) (Nasdaq: COHR) is the most powerful diode-pumped, solid state green laser currently available that delivers diffraction limited output. Specifically, this new laser provides 45W of average power (at 120 kHz) at 532 nm, in a single mode output beam (M2 < 1.3), making it over twice as powerful as the nearest competitive model.
The unique combination of high power, high repetition rate and excellent mode quality make the AVIA 532-45 an ideal source for precision micromachining applications that require both high throughput and precision edge quality (minimized heat affected zone). Examples include singulation of QFN, FBGA, and µSD (MMC) as well as Direct Chip Attach (DCA) type packages. These same characteristics are also advantageous in solar cell processing applications such as edge isolation of crystalline devices, and P2 and P3 scribing of thin film cells.
The AVIA 532-45 incorporates the same high precision pulse control features found in lower power AVIA models. These include PulseEQ(TM) to deliver constant pulse energy over time, even with varying repetition rates, and ThermEQ(TM) to guarantee uniform pulse energy when the laser is operated in burst mode. These enhance process consistency and flexibility by providing the ability to regulate the energy delivered to the work surface without any change in beam parameters.
Founded in 1966, Coherent, Inc. is a Russell 2000 Index company and a world leader in providing laser-based solutions to the commercial and scientific research markets.
