Arlon HF PCB Built on AD450 50mil 1.27mm DK4.5 With Immersion Gold for Wide Band Antennas

Rogers' (Arlon) AD450 is a woven fiberglass reinforced, ceramic filled, PTFE based composite material for use as a printed circuit board substrate. The woven fiberglass provides better dielectric constant and thickness uniformity, better dimensional stability as well as reduced manufacturing costs.

The electrical properties of AD450 suggest it can readily replace FR-4 in applications where higher frequencies and expectations for increased fidelity with broadband signal are beyond the performance offered by FR-4.

With a dielectric constant of 4.5, most FR-4 designs can be readily transferred. Its higher thermal conductivity and lower CTE also promote its use in higher power designs, where temperature extremes and heat rejection are primary considerations.

AD450 is compatible with processing used for standard PTFE based printed circuit board substrates. In addition, its low Z-axis thermal expansion will improve plated through hole reliability, compared to typical PTFE based laminates.

Typical Applications:

1. Circuit Board Miniaturization

2. Multimedia Transmission Systems

3. Wide?Band Antenna Applications

4. Replacement of FR-4 in Higher Frequency Applications
