Double Layer Rogers PCB Built on 20.7mil RO4003C LoPro Reverse Treated Foil for Low Noise Block.
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
RO4003C LoPro laminates use a proprietary Rogers' technology that allows reverse treated foil to bond to standard
RO4003C dielectric. This results in a laminate with low conductor loss for improved insertion loss and signal integrity
while maintaining all other desirable attributes of the standard RO4003C laminate system.
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
- Meets environmental concerns
CAF resistant
