The Rogers RO4350B laminate material is a popular choice for high-frequency circuit board applications that require excellent electrical performance. With its unique ceramic-filled PTFE composite construction, RO4350B offers superior high-frequency signal integrity compared to traditional FR-4 laminates. But how much does this advanced material cost? Here’s an overview of Rogers RO4350B pricing.

Key Rogers RO4350B Price Factors

Rogers RO4350B is available in a range of dielectric constant options from 3.48 to 10.2 to suit different circuit impedance needs. Higher dielectric constants are more expensive. Panel size is another key price factor – larger panels cost more per square foot but enable improved fabrication yields and lower costs for high volume orders. Finally, order quantity affects pricing with discounts for larger orders.

Rogers RO4350B Price Per Square Foot

Here are typical Rogers RO4350B prices per square foot for a 24″ x 18″ panel:

Dielectric Constant	Price Per Square Foot
3.48	$46.15
6.15	$57.40
10.2	$77.55

As shown, the 10.2 dielectric constant material costs around 70% more than the 3.48 version.

Comparing Rogers RO4350B vs FR-4

The premium performance of Rogers RO4350B comes at a cost. RO4350B costs approximately 4-6 times more than conventional FR-4 laminates. However, for circuits operating above 3-4 GHz, RO4350B is usually worth the additional expense due to its superior signal integrity.

Conclusion

With prices ranging from $46-78 per square foot, Rogers RO4350B provides high performance but at a premium cost over FR-4. Careful design to minimize layer count and panel utilization is key to controlling fabrication costs with RO4350B.

Frequently Asked Questions

Q: Does Rogers offer any discount pricing programs?

A: Yes, Rogers offers volume discount pricing once certain order quantity thresholds are met. Contact a Rogers sales representative for details.

Q: Is Rogers RO4350B more difficult to fabricate than FR-4?

A: Due to the ceramic filler, RO4350B is more abrasive on tooling than FR-4. However, most experienced PCB manufacturers can work successfully with RO4350B using diamond-tipped drill bits and router tools.

Q: Can Rogers RO4350B be used for multilayer boards?

A: Yes, RO4350B laminates are very commonly used for multilayer boards requiring high frequency performance. The material is available prepreg form for multilayer layup and bonding.

Q: Does Rogers offer any low-cost alternatives to RO4350B?

A: Rogers 4003C and 3003 laminates offer more budget-friendly options, trading off some performance for significantly lower cost than RO4350B.
