RF-10 High Frequency PCB with Immersion Tin Finish
1.Introduction of RF-10
RF-10 copper clad laminates are composites of ceramic filled PTFE and woven fiberglass. RF-10 offers the advantage of high dielectric constant and low dissipation factor. The thin woven fiberglass reinforcement provides both low dielectric loss and improved rigidity for better handling and dimensional stability in multilayer circuits.
Engineered as a cost-effective substrate, RF-10 meets the industry's need for size reduction in RF applications. It bonds well with smooth low profile copper, and its low dissipation characteristics combined with smooth copper foil minimize insertion losses at higher frequencies where skin effect is significant.
