4 Layer RF Circuit Board On Rogers 60mil RO4350B and 10mil RO4350B with Back Drill for UHF Coupler
This 4 layer RF PCB is built on 60mil RO4350B and 10mil RO4350B for the application of UHF coupler. Look at the stack-up.
Base materials are 60mil RO4350B core and 10mil RO4350B core plus 4mil RO4450F prepreg. There’re 35 μm(1oz) copper on each layer with final height 2.1mm thick. Pads are immersion gold plated. There’re back drilled via from 10mil core. Back drilling can reduce noise interference and improve signal integrity. Using back drilling successfully reduced the difficulty of PCB fabrication and avoided the use of buried /blind via.
Features and benefits
1) RO4350B exhibits a stable dielectric constant over a broad frequency range;
2) RO4350B makes it an ideal substrate for broadband applications;
3) Delivery on time higher than 98% on-time-delivery rate;
4) Focusing on small batches and medium volume production;
5) Strict WIP inspection and monitoring as well as working instruction;
Applications
Antenna, Interference filter, Sound control switch induction, Trunk amplifier etc
