What is the Standard PCB Thickness? The Complete Guide in 2024

Splet20. jul. 2024 · The thickness of a Prepreg material depends on the amount of resin content bound with the glass fiber. Based on the amount of resin content, prepregs can be divided in to three types - Standard Resin (SR), Medium Resin (MR) and High Resin (HR). High resin results in thicker prepreg materials that are more expensive. SpletThe thickness of the separation between layers must be at least .005" to maintain the filling medium's integrity, prepreg. Any voids or pockets will degrade the dielectric value seriously. The standard prepreg FR4 type multi-layer is not suited to medium or high voltage work.
