Rogers
AD450 High Frequency PCB Built on 10mil 0.254mm Substrate With Immersion Gold
for Wide Band Antennas.
(Printed
Circuit Boards are custom-made products, the picture and parameters shown are
just for reference)
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.
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
