Material Notes:

49N is a low-flow epoxy prepreg engineered for bonding multilayer epoxy rigid-flex or attaching heat sinks to multilayer PCBs. With a high Tg, the prepreg can be used in high-performance or high-temperature applications compared to a standard difunctional epoxy low-flow.Multifunctional epoxy resin system with a Tg of 170°C offers improved high-temperature and PTH reliability.Engineered with discrete flow ranges and fiberglass styles to optimize flexibilityElectrical and mechanical properties meeting the requirements of IPC-4101/21, modified to be "Low-Flow"RoHS/WEEE compliantShort cure (45 minutes at 360°F) for improved manufacturing productivityTypical Applications:Bonding multilayer epoxy rigid-flexBonding adhesiveless epoxy rigid-flexAttaching heat sinks to multilayer PCBsDielectric insulators|This data represents typical values for the production material and should not be used as material specifications.Information provided by ARLON Silicone Technologies Division.
