Laser dicing from OpTek Systems is used for a range of requirements from the singulation of micro-electronic devices to the re-sizing of wafers or substrates.
With a diverse range of laser parameters available to us, OpTek are able to apply laser dicing to materials including silicon, ceramic, diamond, polymers, and composites, making it suitable for applications including electronics, micro-electronics, photovoltaics, and plastic electronics. As there are no blades or mechanical contact involved with laser processing, chips, and cracks associated with mechanical processing are avoided, furthermore, there is no mechanical wear to worry about. Laser dicing can be configured either for through cutting or for partial thickness cutting and can achieve narrow street width at high feed rates.
Laser dicing of materials like silicon and polymer, making it suitable for conventional and plastic micro-electronics. Laser processing provides an alternative to conventional mechanical sawing, with the added flexibility to meet the challenges of new developments in electronics.
Full-thickness (through) cutting provides the flexibility to create curves, circles, and other non-straight profiles, in addition to the more conventional straight-line cuts. Through cutting also makes it possible to dice out sections, or devices from the center of a wafer, without damage to the surrounding material. Partial-thickness laser dicing provides fast, accurate, and reproducible processing of a substrate, which can then be reliably cleaved or snapped into individual die. This scribe and snap approach delivers the advantages of high speed, narrow kerf processing, with minimized machining debris and low thermal impact. Laser dicing can also be applied to virtually any material, addressing applications for ceramic, diamond, and other super-hard materials.
