Multilayer High Frequancy PCB Board Rogers 5-Layer PCB Board Bulit On 20mil RO4003C

Hi Everyone,

Today, we're going to talk about 5-layer high frequency PCB made on Rogers RO4003C.

5 layer PCB is fabricated on 3 cores of RO4003C and etched 1 layer copper off to achieve 5 layers.

Viewing from the stack up, we can see 3 sheets of 20 mil cores achieve the basic layer structure, 2 layers of bondply bond the 3 cores which result in 5 layer board.

Copper weight in inner-layer is half ounce, outer-layer 1 ounce.

This is the picture of microsection, which can more intuitively reflect the structure of the board.

No solder mask is applied on the surface, pads are immersion gold.

Actually the stack up of multilayer PCBs can be done in many different ways according to the different requirements or applications for controlled impedances, signal transmission etc. There’re many types cores for our designer to choose in RO4003C laminates, such as 8mil, 12mil, 16mil, 20mil etc.

We have a variety of high frequency materials for customers to choose from, the main are Rogers 4000 series, 3000 series, 5000 series and 6000 series, Taconic TLX series, TLY series etc. and Chinese F4B series etc.
