RO4350B LoPro RF PCB Rogers 60.7mil Reverse Treated Foil PCB Circuit Board With Immersion Gold
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
Product Description
RO4350B LoPro laminates utilize proprietary Rogers technology that enables reverse treated foil to bond with standard RO4350B dielectric. This results in a laminate characterized by low conductor loss, enhancing insertion loss and signal integrity while preserving all desirable attributes of the standard RO4350B laminate system.
