Polyimide Flex PCB
【Brief】:This is a type of flexible PCB built on polyimide 76 micron substrate with 90 ohm impedance
controlled on 0.15mm/0.3mm track and gap for the application of Wireless Broadband. It's
standard 0.20 mm thick with yellow solder mask (coverlay) on both sides and immersion
gold are on pads. FR-4 as stiffener is on the head and tail.
【Series】:Flexible PCB
