Park Electrochemical Nelco® N4000-11 BC® Buried Capacitance™ Epoxy Laminate and Prepreg

The Nelco® N4000-11 is a CAF resistant, high Tg (175º C by DSC) multifunctional epoxy dielectric substrate. This material is formulated to provide the PWB manufacturer and OEM with vastly improved thermal, mechanical, and electrical performance in lead-free assembly and high layer count, sophisticated PWB designs. The Nelco N4000-11 BC® is offered as a buried capacitance solution, offering a greater degree of design freedom for smaller, more reliable assemblies.Key Features and Benefits:Tg >175ºC, thermal stability and moisture resistanceCAF ResistantLow Z-axis expansionDicyandiamide (DICY) free, proprietary resin chemistrySuperior electrical propertiesBuried Capacitance SolutionOptimized FR-4 processingApplications/Qualifications:High Density InterconnectsLead-Free Assembly SubstrateLarge Format BackplanesTight Tolerance Via to Via ApplicationsHigh I / O Count BGA SubstratesExtreme Layer count MultilayersLead-Free DCA ApplicationsHigh Temperature Underhood AutomotiveTelecommunications InfrastructureSophisticated Data Storage ApplicationsRoHS CompliantMeets IPC-4101/28, /83, /98, /99 SpecificationsInformation provided by Park Electrochemical Corp.
