Isola Group and Circuit Foil launch ultrathin 40 μm laminate

Article Type: New products From: Circuit World, Volume 38, Issue 4

Isola Group S.à.r.l., a leading global material sciences company that designs, develops, manufactures and markets copper-clad laminates and dielectric prepreg materials used to fabricate advanced multilayer printed circuit boards (PCBs) and Circuit Foil Luxemburg S.à.r.l., a manufacturer of high-quality electrodeposited (ED) copper foils, announced today the launch of ultrathin 40 μ) laminate. The two companies have jointly developed the product, which will initially be available in high glass-transition temperature (Tg), phenolic-cured resins. The product has a glass-transition temperature in excess of 170°C.

The product is a major improvement over existing technologies, as the laminate is glass reinforced and therefore does not have thermo-mechanical mismatch issues commonly associated with unreinforced films. The mechanical properties, such as the Young’s modulus (Tensile Modulus), and thermal expansion coefficient are similar to high-Tg systems, as opposed to a low value of the modulus and high values of thermal expansions typical with ultrathin film. The low modulus and high thermal expansion coefficients of unreinforced products cause interlaminar stresses during the high temperature assembly process leading to delamination issues.

Tarun Amla, Executive Vice President and Chief Technology Officer at Isola Group, stated, “I am pleased to report that Isola, together with Circuit Foil, has overcome the challenges of lower dielectric strength, thickness control and handling associated with the manufacturing of ultrathin, glass-reinforced laminates with a unique technical solution. The dielectric strength of the product will fulfill the growing need in the market for reliable, thinner laminates.”

Raymond Gales, Customer Care and Group Quality Director at Circuit Foil, added, “We are very excited with the launch of the product and are looking forward to working with Isola on the next-generation ultrathin laminate and other technologies involving our newest generation of foils with ultraflat profiles.”

The product will be marketed and distributed by Isola Group out of its Chandler, AZ facility. For more information, please contact Customer Service or call 480-812-2511.
