Rogers Introduces
Liquid Photoimageable Solder Mask for
Flexible Circuit Boards
-- Allows Fabrication of Flexible Circuits with Fine Patterns --
Rogers, CT, September 23, 1997: Rogers Corporation introduces R/flex® 8080LP liquid photoimageable covercoats, a line of materials that are ideal for flexible circuit applications where fine pattern resolution, moisture resistance, and creasability are important. The demand for rugged flexible circuits with finer lines and higher densities is growing, particularly for hard disk drive, automotive underhood, and chip packaging applications. The combination of an R/flex 8080LP covercoat and an R/flex high performance flexible circuit material can produce a high resolution flexible circuit that withstands rigorous environments. The new covercoat offers a savings over conventional coverfilms.
Rogers is extending its ability to serve customers who need specialized material technology, along with high performance laminates, to serve their markets. The R/flex 8080LP photoimageable covercoats have been used by major electronics companies in Japan for several years, where they are sold as NPR-80 products by the Nippon Polytech Corporation of Tokyo. Rogers is the exclusive distributor for these covercoats in the U.S., and has additional distribution rights for Europe.
Rogers liquid photoimageable covercoats can be easily processed using conventional methods and process chemistries, including screening, spray coating, curtain coating, and photoimaging. The new covercoats are alkaline developable solder resists. With proper exposure, development, and cure, the covercoats allow the direct imaging of very precise patterns for fineline circuits.
The R/flex 8080LP3 formulation meets the chemical compatibility requirements of the hard disk drive industry. All of the new R/flex 8080LP covercoat products are resistant to plating chemistries, including for electroless Ni and Au plating, and have excellent process stability, with outstanding adhesion and heat resistance. The products also have a long shelf and pot life, and good electrical insulation properties. Data related to these properties, and to viscosity, physical properties of the film, plating resistance, curing temperature and time, resolution and photosensitivity, electrical resistance, and other test results, are available from Rogers.
Rogers manufactures specialty materials, including laminates for flexible, microwave, and high frequency printed circuits. Headquartered in Rogers, CT, U.S.A., Rogers business locations include Connecticut, Arizona, Illinois, Belgium, Japan, and Hong Kong.
