Double Layer Rogers PCB Built on 12.7mil RO4003C LoPro Reverse
Treated Foil for High Speed Back Planes.
With the help of a unique Rogers' technology, reverse-treated foil
can be joined to regular RO4003C dielectric in RO4003C LoPro
laminates. As a result, the laminate retains all of the desirable
characteristics of the typical RO4003C laminate system while having
reduced conductor loss for better insertion loss and signal
integrity.
Features and Benefits:
RO4003C materials are reinforced hydrocarbon/ceramic laminates with
very low profile reverse treated foil.
1. Lower insertion loss
2. Low PIM
3. Increased signal integrity
4. High circuit density
Low Z-axis coefficient of thermal expansion
1. Multi-layer board capability
2. Design flexibility
Lead-free process compatible
1. High temperature processing
2.Meets environmental concerns
CAF resistant
