Rogers Introduces 92ML Thermally Enhanced Laminates and Prepregs


Reading time ( words)

Rogers Corporation has introduced 92ML materials. These thermally enhanced laminates and prepregs are specifically engineered and manufactured to meet the demands of high power applications. 92ML materials are halogen-free, flame retardant, thermally conductive epoxy based prepreg and laminate systems. They provide a low-cost, lead-free solder compatible system with enhanced heat transfer characteristics. These materials are ideal for multilayer applications requiring thermal management throughout the entire board.

The 92ML laminate materials are available with up to 4oz copper cladding; thick enough to meet today’s most demanding power distribution requirements. The high thermal conductivity of up to 3.5 W/mK (in-plane) in combination with the relative ease and familiarity of epoxy based systems makes this material an ideal candidate for applications such as motor controllers, power supplies, converters, automotive electronics, etc. The relatively high Tg value of 160°C in combination with a low Z-axis coefficient of thermal expansion of 22ppm/°C (g) and 175ppm/C (>Tg) ensure that the 92ML materials survive lead free solder exposures and board reliability testing. The excellent rheological characteristics of the 92ML prepregs enable a high degree of resin flow; a critical element of high power multi-layer board processing.

Additionally, 92ML laminates are also offered in combination with an aluminum plate to form an insulated metal substrate (IMS). This product is known as 92ML StaCool™ laminate. In this configuration, the product has an integrated heat sink that can be machined and formed to serve as a mechanical chassis in the final application. 92ML StaCool laminate is characterized as having a high level of thermally stable adhesion to the aluminum substrate. This laminate withstands over 7 minutes of 288°C solder exposure enabling sufficient time for final product to be assembled without issues. 92ML StaCool laminate is useful in high power and operating temperature applications such as LED modules, automotive lighting, power devices, etc.

It’s always fun to talk with a company that can do something different—in this case, ultra-heavy copper PCBs, meaning over 20-ounces copper. Wanting to know more, Dan Beaulieu talked to Aurora Circuits’ Director of Business Development Thad Bartosz.

Simulation Technology in Acid Copper Pattern Plating

07/17/2020 | Pete Starkey, I-Connect007
PCB designers and CAM engineers may feel there is little they can do to achieve uniform finished copper thickness of PCB traces and holes. But in an illuminating discussion with Robrecht Belis, manager of surface finishing and e-coating with Elsyca NV in Belgium, Pete Starkey learned that nothing could be further from the truth, provided they act on time and use the right tools.
