Flexible Base Dielectrics for Use in Flexible Printed Boards
This document provides comprehensive data to help users more easily determine both material capability and compatibility for flexible base dielectric materials for manufacture of flexible printed boards. It includes flexible base material specification sheets that have been updated with the newest properties for the specification material types. It establishes the most current classification system, qualification and quality conformance requirements, including high frequency dielectric properties. A new specification sheet for an adhesive fluorocarbon film has been added as it became available to the marketplace.
Recommended Drawing Call-Outs
- Specifying a slash sheet from this specification is the best way to designate the right material to be used
- Refrain from specifying laminate or prepreg by brand name, Tg, or Td
