4 Layer High Frequency PCB Built On RO4350B With Blind Via and Immersion Gold

(PCB’s are custom-made products, the picture and parameters shown are just for reference)

General Description

This is a type of 4-layer HDI high frequency PCB circuit board built on RO4350B with RO4450B prepreg for the application of radar RF board. It's a multilayer layer RF PCB board at 1.0 mm thick with immersion gold finish and solder mask and silkscreen. This board contains blind via from top layer to inner 1, top layer to inner 3. Since it's asymmetric buildup, 1.2% warpage is allowed. It's fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 20 boards are packed for shipment.

Features and benefits

The temperature coefficient of dielectric constant is among the lowest of any circuit board material, making it ideal for temperature sensitive applications.

Reducing signal loss in high frequency application meets the development needs of communication technology.

Excellent high frequency performance due to low dielectric tolerance and loss.

Gold has high solderability, no stressing of circuit boards and less contamination of PCB surface.

Engineering design prevents problems from occurring in pre-production.

100% tests inclusive of electrical test and AOI inspection.

Fast and flexible to save the time of production from prototype to standard production

Great customer service

UL recognized and RoHS Directive-compliant

Application

RF module, Power splitter, Low Noise Block, 3G antenna
