Product Description

Brief Introduction

RO4350B High Frequency Circuit Material is glass reinforced hydrocarbon/ceramic laminates (Not PTFE) designed for performance sensitive, high volume commercial applications. Currently double sided and multilayer RO4350B PCB’s are available at Bicheng company. Double sided RO4350B PCB with thickness 10mil (0.254mm), 20mil (0.508mm), 30mil (0.762mm) and 60mil (1.524mm) are the bestsellers. We provide prototype runs, small batches and volume production services.

Advantages

General description

This is a type of double sided PCB built on high frequency substrate with Tg 288°C for the application of WiFi attenuator. It’s 0.8 mm thick, white silkscreen over green solder mask. All via’s are open to air. Pads are covered by immersion gold. The base material is used from Rogers RO4350B, entire board supplying 1 PCB up. They’re fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 25 panels are packed for shipment.
