Product Overview

(Note: Custom PCBs are tailored products; images and specifications provided are for reference purposes.)

The RO4350B 0.25mm 2-layer PCB is an ultra-thin, high-frequency circuit board that perfectly balances RF performance with manufacturing cost-efficiency. Utilizing Rogers' proprietary woven glass reinforced hydrocarbon/ceramic material, this PCB delivers exceptional electrical characteristics (Dk 3.48±0.05) while maintaining processability similar to standard FR-4. The 0.25mm thin profile, combined with a copper-matched CTE, ensures high reliability for plated through-holes under demanding thermal conditions. Rated UL 94 V-0 with low water absorption (0.06%), it is the ideal choice for compact, high-power RF designs.

Frequently Asked Questions

What are the primary benefits of using Rogers RO4350B material?

RO4350B offers excellent high-frequency performance with a low dielectric loss, tight Dk control, and thermal stability similar to FR-4, making it highly cost-effective for RF designs.

Is this ultra-thin 0.25mm PCB suitable for high-power applications?

Yes, the hydrocarbon/ceramic construction provides superior thermal conductivity compared to standard PTFE materials, allowing it to handle higher power in a slim form factor.

What surface finish is used on this RO4350B PCB?

This specific design uses Immersion Silver, which provides excellent conductivity and a flat surface for high-frequency signal integrity.

Can I use standard FR-4 assembly processes for this board?

Yes, one of the key advantages of RO4350B is that it can be processed using standard automated assembly and soldering techniques, unlike some other high-frequency laminates.

Does this PCB meet international quality standards?

Absolutely. The PCB is manufactured to IPC-Class-2 standards and is 100% electrically tested prior to shipment to ensure zero defects.

What file formats are required for ordering?

We primarily accept Gerber RS-274-X files, but can also work with PCB.Doc and other industry-standard design formats.
