For some designs, dielectric PCB properties are critical
Rogers Corporation has long been the industry heavyweight for advanced electronic PCB materials. Supplying Rogers PCB materials that are aimed at “Helping power, protect, and connect our world” Rogers Corporation has many material types aimed at solving issues within many industries.
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. Rogers 4350 is famous material for manufacturing of PCB.
But when advanced electrical properties and performance are critical to your designs, Rogers Corporation’s materials delivers:
- Lower Dielectric loss
- Low electrical signal loss
- Wide range of Dk (dielectric constant) values (2.55-10.2)
- Low cost circuit fabrication
- Low out gassing for space applications
Sunstone Circuits can deliver your RF, Microwave and mobile designs with the same industry-leading lead times, quality, and extreme customer support you’ve come to expect from all our services, only now with better advanced PCB material dielectric properties.
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.
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. So these materials are used to make High Frequency PCB.
