Material Notes:
The Nelco N5000 BT epoxy laminate and prepreg system provides superior electrical properties. The N5000 resin system wasoriginally developed for application specific use in high densitymilitary and commercial boards requiring not only close thicknesstolerance, but also the ability to withstand the stress of multiple soldering excursions and repeated chemical exposure.Key Features and Benefits:BT resin chemistryExcellent Reliability and PerformanceCAF ResistantWide processing latitudeApplications/Qualifications:Fine-Line MultilayersBackplanesSurface-Mount MultilayersBGA MultilayersMCM-LsDirect Chip AttachWireless CommunicationsHigh Density InterconnectsRoHS CompliantMeets IPC-4101/30 SpecificationsInformation provided by Park Electrochemical Corp.
