FOR SOME DESIGNS, PCB DIELECTRIC 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 have added more materials to our arsenal. One example of these added materials is Rogers 4000-series. These low-loss dielectric materials mean greater performance for your high-demand PCB prototypes or production.

You can get more information on all of Rogers' laminate products here, in the Rogers High Frequency Laminates Product Selector Guide.

Glossary:

Dielectric Materials

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.

Pre-impregnated (Pre-preg)

Contraction of "pre-impregnated composite fibers", and in the manufacture of PCBs, pre-pregs 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 multilayer PCB together.

A thin prepreg layer is the most common HDI substrate. It provides good reliability, process-ability and reasonable cost.

Typical thickness of prepreg HDI layer is 60u +/-20u. Typical laser hole diameter (drilled top) is 100 - 150u.

Another option is RCCu (Resin coated copper foil) which is used in applications that require extremely good drop test performance. Aspocomp has process capability for halogen-free RCCu and stock of 50,60 and 75u RCCu. Please check case by case the availability of RCCu.
