Rogers RF PCB Built on Kappa 438 30mil 0.762mm DK 4.38 with Immersion Gold for Small Cells.
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
 
Rogers Kappa 438 laminates were designed using a glass reinforced hydrocarbon ceramic system that offers
superior high frequency performance and low cost circuit fabrication resulting in a low loss material which can
be fabricated using standard epoxy/glass (FR-4) processes. Kappa 438 laminates also have the UL 94 V-0
flame retardant rating and are lead free solder process compatible.
 
Kappa 438 laminates offer dielectric constants (Dk) tailored to FR-4 industry standard norms which facilities
ease of converting existing FR-4 designs where better electrical performance is needed.
 
Features
1. Glass reinforced hydrocarbon thermoset platform
2. Dk of 4.38 is tailored to FR-4 industry standard norms
3. Tighter Dk and thickness tolerance than FR-4
4. Low Z Axis CTE of 42 ppm/°C
5. High Tg of > 280°C TMA
6. Meets UL 94-V0 requirements
 

 
Benefits
1. Ease of PCB manufacturing and assembly in Line with FR-4
2. Design Dk enables ease of converting existing FR-4 designs needing better electrical performance
3. Consistent circuit performance
4. Improved design flexibility and plated through-hole reliability
5. Automated assembly compatible
 
Typical Applications:
1. Carrier Grade WiFi/Licensed Assisted Access (LAA)
2. Small Cell and Distributed Antenna Systems (DAS)
3. Vehicle to Vehicle/Vehicle to Infrastructure Communications (V2X)
4. Internet of Things (IoT)
Segments: Smart Home and Wireless Meters
