Maximizing Design Potential with RO4350B PCB

For engineers developing advanced high-frequency circuits, RO4350B laminates from Rogers Corporation strike the ideal balance of electrical performance, manufacturability and value.

Precise Composition
RO4350B's proprietary woven glass composite achieves tight uniformity in its Dk of 3.48±0.05, even at mm-wave frequencies. Randomly oriented reinforcement preserves isotropic properties critical for multi-layer designs.

Process Compatibility
Identical processing to FR-4 epoxy/glass means existing assembly lines require no changes to adopt RO4350B. Our engineers leveraged this in prototyping a 2-layer automotive radar board, meeting tight 4/4mil dimensions on the first pass.

Dimensional Stability
Thermo-mechanical properties like 10-12ppm in-plane and 32ppm z-axis CTE perfectly match standard copper foils. This prevents delamination in mixed-material stacks. RO4350B’s Tg above 280°C maintains properties regardless of assembly temperatures.

Proven Performance
Our radar prototype demonstrated trouble-free operation from -40°C to 105°C after environmental stress testing. Other projects up to 40GHz show RO4350B’s consistency even at mm-wave frequencies.

Whenever cost, manufacturability and performance must be balanced, trust RO4350B to open new design possibilities. Contact us to leverage this versatile substrate in your next high-frequency product.
