For some designs, dielectric PCB properties are critical.Whether it’s high-speed designs, RF, microwave, or mobile applications – where power management is key, you’re finding more situations that require dielectric PCB properties in your prototypes that standard FR-4 just can’t deliver. We know that. That’s why we’ve added Rogers 4000-series dielectric materials to our PCB Express. Quick-turn product line. These new low-loss dielectric materials mean greater performance for your high-demand Rogers PCB prototypes.
Why Rogers Dielectric Material?
FR-4 material provides the base standard for PCB substrates, delivering a widely effective balance between cost, maneuverability, electrical properties, durability and performance.
But when electrical properties and performance are critical to your designs, Rogers 4350 delivers:
- Lower Dielectric loss;
- Low signal loss;
- Low cost circuit fabrication;
- Suitable for quick-turn prototyping applications.
A dielectric material is a substance that is a poor conductor of electricity, and used as an insulating layer in the PCB build up. Porcelain, mica, glass, plastics and some metal oxides are good dielectrics. The lower the dielectric loss, (the proportion of energy lost as heat) the more effective the dielectric material. If the voltage across a dielectric material becomes too great — that is, if the electrostatic field becomes too intense — the material will suddenly begin to conduct current. This phenomenon is called dielectric breakdown. Rogers 4350 is less likely to demonstrate a dielectric breakdown condition than FR-4.
Pr-impregnated Contraction of ‘per-impregnated composite fibers’, and in the manufacture of PCBs, per-pregs (PP)help influence the performance characteristics of the printed circuit board.
A term also used in the PCB fabrication industry to describe the bonding ply materials used to bond the layers of a multi-layer PCB together.
