Abstract
Electronic circuits such as IC packages, circuit boards, of flex circuits are singulated by laser cutting of adjoining laminated material. The laser beam has a wavelength of less than 400 nm, and either a minimum energy density of 100 J/cm2 or a minimum power density of 1GW/cm2. The method avoids the need for cleaning and intermediate handling, and there is a greatly improved throughput.
