RO4350B
LoPro High Frequency PCB 10.7mil Rogers Reverse Treated Foil Circuit Board With
Immersion Gold
(Printed
Circuit Boards are custom-made products, the picture and parameters shown are
just for reference)
RO4350B
LoPro laminates results in a laminate
with low conductor loss for improved insertion loss and signal integrity while
maintaining all other desirable attributes of the standard RO4350B laminate
system.
