Isola Revamps IS620
November 30, 2006 |Estimated reading time: Less than a minute
CHANDLER, Ariz. Isola Group S.a.r.l. used process changes, without adjusting the chemical make-up, to improve dielectric and thermal performance of IS620, a base material for low-loss, high-speed space.
The product offers 25% lower dielectric loss than the previous iteration, with loss at 0.005 0.007 GHz with splitpost and stripline tests. Improving thermal performance complements the complex designs with sequential buildups and hybrid configurations in lead-free and mixed-mode assemblies, according to the company. Simulated testing on the company's seven-zone reflow oven with multiple designs and excursions reached peak temperatures of 230° 290°C.
Based on these results and design, processing, and fabricator variants, the company will define processing parameters for validation, said Tarun Amla, vice president and CTO, adding that they plan to collaborate with the company's new product introduction group. The product should be manufactured in Europe and Asia, as well as in the U.S.
