Coherent's Latest Lasers Cut Thicker Films, PCBs, and Flex Substrates

Reading time ( words)

Coherent has expanded its AVIA industrial nanosecond laser family with the addition of a high-power ultraviolet (355 nm) and green (532 nm) lasers. Specifically, the new AVIA 355-55 features a very high (150 kHz) pulse repetition rate, resulting in an average power of 55 W at 355 nm. The AVIA 532-80 produces high (1 millijoule) pulse energy, which, together with a maximum pulse repetition rate of 80 kHz, translates into an average power of 80 W.

AVIA ultraviolet lasers are used for cutting flex substrates and thin printed circuit boards (PCBs) where higher lateral resolution are a critical consideration. The higher power now available from the new AVIA 355-55 will extend these cutting capabilities to thicker (> 200 µm) flex and multi-layer materials. It will also enable existing applications to be accelerated to higher throughputs, while still delivering the same superior edge quality with minimal peripheral thermal damage.

AVIA green lasers are used for scribing films, drilling holes and slots, and cutting flex substrates that efficiently absorb green wavelengths, including certain PCB substrates, semiconductors, and photovoltaic components. The unique, high pulse energy of the new AVIA 532-80 provides high piercing capabilities for drilling, cutting and scribing, deeper features and thicker substrates than competitive lasers. And the 80 kHz repetition rate ensures high process throughput.
