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)
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.
