Isola Slash Sheets

Isola laminate and prepreg materials are certified to IPC-4101 or IPC-4103.

IPC-4101, “Specification for Base Materials for Rigid and Multi-layer Printed Boards,” covers the requirements for laminate or prepreg used primarily for rigid or multi-layer printed boards for electrical and electronic circuits. Each specification sheet outlines requirements for both laminate and prepreg for each product grade. The specification sheets are organized by reinforcement type, resin system and/or construction, and are provided with a specification sheet number for ordering purposes.

IPC-4103, “Specification for Base Materials for High Speed/High Frequency Applications,” covers the requirements for high speed/high frequency performance plastic substrates used for the fabrication of printed boards for microstrip, stripline and high-speed digital electrical and electronic circuits. This specification applies to the plastic substrate thickness defined in the specification sheet as measured over the dielectric only. Laminates controlled by this specification usually have a dissipation factor of less than 0.005.
