A lead-free compatible substrate with enhanced electrical performance

The improved IS415, a 200oC Tg product from Isola Group, is currently available in North America, with manufacturing in Asia to begin early in 2007. It is a RoHS compliant, UL94V-0 rated substrate, well suited not just for lead-free applications, but also in products that require high reliability and good signal integrity. The electrical loss numbers will now be in the 0.009 range, using the split post resonant cavity method and around .0135 using the Bereskin Stripline test method at 10 GHz.

According to the company, the improvements were made to address the need for higher bandwidth and faster data rates. Reportedly, this improvement brings the electrical properties very close to typical mid Dk Df products at almost cost parity with much higher dielectric loss Phenolic cured systems. The high decomposition temperature and low thermal expansion properties of the substrate offer thermal reliability performance comparable to or beyond the firm’s lead-free compatible materials 370HR and IS410. In addition, its low loss properties, combined with its stable and predictable dielectric constant, make this product well suited for high-speed applications.
