5 Layer Hybrid PCB Built On 10mil RO4350B and FR-4 with Immersion Gold for 2.4 Ghz Antenna
(Printed circuit boards are custom-made products, the picture and parameters shown are just for reference)
Hello everyone,
Warm greetings!
Today we’re going to introduce a type of 5-layer PCB built on mixed RF material RO4350B and epoxy glass FR-4. It’s for the application of 2.4 Ghz Antenna. It's 1.0 mm thick with through holes. Green solder mask covers both sides and immersion gold on pads. They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 25 boards are packed for shipment.
The above drawing is the stack-up. “Layer 2” is etched off and left 5 layers of copper on board.
Features and benefits
1) Signal integrity performance improved over the stack-ups with all FR4 board;
2) Quick CADCAM checking and free PCB quotation;
3) No MOQ, low cost for prototypes and small runs quantity;
4) IPC Class 2 / IPC Class 3 standard.
Applications are wide, for example, consumer electronics, antenna WiFi, 8 port switch, embedded computer DC transformer, inverter auto, WiFi 4G router and temperature module etc
