PCBs manufactured using Rogers RO4350B as a substrate can be referred to as Rogers RO4350B PCBs.So, what are the benefits of this material?
Rogers RO4350B HF material is a glass fiber reinforced (non-PTFE) hydrocarbon/ceramic laminate designed for high-volume, high-performance commercial applications.RO4350B is designed to provide superior RF performance and cost-effective circuit production. It is a low-loss material that can be produced at a competitive price using standard epoxy/glass (FR4) processes. As operating frequencies increase to 500 MHz or higher, designers typically have significantly fewer laminates to choose from. The RO4350 PCB has the characteristics required by RF microwave developers to enable repeatable design of impedance-controlled transmission lines for filters, coupling networks, and networks. The low dielectric loss allows the use of RO4350 series materials in many applications where higher operating frequencies limit the use of laminates for conventional printed circuit boards. The temperature coefficient of the dielectric constant is one of the lowest of all printed circuits, and the dielectric constant is stable over a wide frequency range which makes it an ideal substrate for broadband applications.
Hole quality should be used to determine tool life rather than tool wear.RO4350 material provides good hole quality when drilled with an Ep-Oxy/glass-compliant drill. The roughness of the material holes RO4350 does not increase significantly when the tool is used compared to Ep-Oxy/glass. Typical values vary between 8 and 25 microns regardless of the number of visits (evaluated up to 8,000 visits). The roughness is directly related to the ceramic filler size is directly related to the size of the ceramic filler and provides a favorable morphology for adhesion to the pore walls. It has been found that holes drilled for epoxy/glass plate conditions have good hole quality with a strike rate greater than 2000.
RO4350B laminates provide tight control on dielectric constant (Dk) and maintain low loss while utilizing the same processing method as standard epoxy/glass. Available at a fraction of the cost of conventional microwave laminates, RO4350B laminates do not require the special through-hole treatments or handling procedures as PTFE based materials. These materials are UL 94 V-0 rated for active devices and high power RF designs.
