4 Layer High Frequency PCB Built On 2 Core of 10mil RO4350B with Immersion Gold for Wireless Antenna System
(Printed circuit boards are custom-made products, the picture and parameters shown are just for reference)
Hello Everyone,
This is a 4-layer RO4350B high frequency PCB built on 2 10mil cores, bonded by 1 sheet of RO4450Fprepreg. As per the requirement of signal transmission, the prepreg can be 1 sheet (4mil), 2 sheets and 3 sheets. This board is for the application of Wireless Antenna System. It's 0.80 mm thick, white legend over green solder mask covered on both sides and immersion gold are on pads. They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 25 panels are packed for shipment.
According to actual applications, the prepreg can be chosen as more plies, for example, following micro-section shows a 3-ply of RO4450F.
