Green Materials for Flex Circuits
August 7, 2007 |Estimated reading time: Less than a minute
ROGERS, Conn. The advanced circuits division of Rogers Corporation (ACMD) released a halogen-free, RoHS-compliant transparent epoxy polyimide laminate product line, R/flex JADE A, which targets flexible circuit needs in portable electronics, computing, packaging, and other applications.
The material received UL 94 V-0 classification for flame-retardant performance. It builds on the company's R/flex CRYSTAL line for "green" manufacturing and high performance in complex assemblies. Thermal stability enables repeated lead-free reflow exposure. Dimensional stability and adjustable squeeze-out reportedly increases yields in fine-pitch, tight-tolerance applications. The material's transparency is claimed to simplify optical inspection.
The product line is available in bonding film, coverlayer, and copper-clad laminate media. It suits use in hard disk drives (HDDs), cell phones, PDAs, laptops, semiconductor packages, and other applications.
