4 Layer High Frequency PCB
Built On 2 Core of 10mil RO4350B with Immersion Goldfor Wireless Antenna System
(Printed
circuit boards are custom-made products, the picture and parameters shown are
just for reference)
Hydrocarbons
or ceramics with woven glass reinforcement make up the majority of Rogers 4350
materials. According to FR4 requirements, they are treated. When mounting
components, such as PTFE materials, Rogers 4350 can help increase the
dielectric strength and does not necessitate the use of specific equipment or
through-hole technology. For active devices and high power RF designs, they
have UL 94 V-0 rating. A superb dimensional stability is provided by them.
This
is a 4-layer RO4350B high frequency PCB built on 2 10mil cores, bonded by 1
sheet of RO4450F prepreg. 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.
