Low Dk / Df FR-4 PCB High Thermal Reliability Printed Circuit Board (PCB) TU-872 Multilayer PCB
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
General Description
TU-872 SLK Sp is based on a high performance modified epoxy FR-4 resin. This material is reinforced with novel woven glass and designed with extra low dielectric constant and low dissipation factor for high speed low loss and high frequency circuit board application. TU-872 SLK Sp material is suitable for environmental protection lead free process and also compatible with FR-4 processes. TU-872 SLK Sp laminates also exhibit excellent CTE, superior chemical resistance, moisture resistance, thermal stability, CAF resistance and toughness enhanced by an allyl network forming compound.
Key Features
1. Excellent electrical properties
2. Dielectric constant less than 3.5
3. Dissipation factor less than 0.010
4. Excellent, stable and flat Dk/Df performance
5. Compatible with most FR-4 processes
6. Lead free process compatible
7. Improved z-axis thermal expansion
8. Anti-CAF capability
9. Superior dimensional stability, thickness uniformity and flatness
10. Excellent through-hole and soldering reliability
