IPC 4103B:2017 PDF Download

IPC 4103B is a standard that outlines the specifications for base materials used in high speed/high frequency applications. Specifically, it covers plastic substrates that are utilized in the fabrication of printed boards for microstrip, stripline, and high-speed digital electrical and electronic circuits. The standard defines the requirements for the thickness of the plastic substrate, specifically measured over the dielectric.

It is important to note that materials controlled by IPC 4103B typically have a dissipation factor of less than 0.005. This factor refers to the ability of the material to dissipate electrical energy as heat, indicating that the materials specified in this standard have excellent electrical performance, making them suitable for high-speed and high-frequency applications.
