Rogers Material

PCB materials are often used as they are cost effective vs. It may also be used to minimize electrical noise to meet stringent performance requirements. RO Series materials are high frequency circuit boards with glass reinforced hydrocarbon and ceramic laminates. Rogers PCBs may consist of both cores and prepreg materials but more often than not, it is a core that carries the top 2 layers of copper with the rest being standard FR4 to reduce cost unless there is an overall very high temperature requirement.

Shown above, the Rogers materials have much less signal loss due to the PCB materials absorbing the signal vs. This is also called PCB material loss.

At about 6 to 7 GHz the signal loss is typically about 0. Rogers ROC vs. The main difference is the has a flammability rating. Electrical Properties are similar as seen below.

Rogers PCB layers may be combined with FR4 layers to achieve improved performance to minimum cost vs. When this is done, the signals need to be put on a Rogers PCB core and not on prepreg. A typical FR4 6-layer stackup is shown below.

Note the prepreg is on the outside to minimize cost as prepreg is lower cost than cores. This is often called a "foil build". However when a Rogers layer is needed the core is on the layers that need it and that is usually the outside layers.

See the 6-layer example below with 3 cores rather than 2 as shown above. This configuration is sometimes called a "Cap Construction" board or a "core build". Rogers and in stock.

Thank you for Signing Up.As you know, printed circuit board plays an important role in electronic products, so you need to consider how to choose the right material in your PCB manufacturing. In general, we use the standard FR-4 material for the printed circuit boards to help customers reduce product costs, which is a fine option, because FR-4 material is affordable and effective for many applications.

In fact, FR-4 refers to a grade of material rather than a material, which is a composite material for glass-reinforced epoxy laminate material. FR-4 is made up of woven fiberglass cloth with an epoxy resin binder that is flame resistant. For electronic engineers and designers, FR-4 glass epoxy is a popular and versatile high-pressure thermoset plastic laminate grade with good strength to weight ratios. With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength.

The material is known to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions. These attributes, along with good fabrication characteristics, lend utility to this grade for a wide variety of electrical and mechanical applications. So FR-4 can perform well in most environmental conditions. Rogers is a company that manufactures the laminate materials that are used to make circuit boards.

This makes them be good for RF circuit boards. FR-4 material has a high Df or dissipation factor than Rogers material, suffering more signal loss.

In impedance stability, Rogers material has a wider range of Dk values than FR-4 material. For dielectric constant, FR-4 features a Dk of about 4. FR-4 material provides the fundamental standard for PCB substrates, keeping a widely effective balance between cost, durability, performance, manufacturability, as well as electrical properties.

However, as performance and electrical properties plays an important role in your designs, Rogers materials have the advantages as follows:. The dielectric materials is a substance with a poor conductor of electricity, and used as an insulating layer in the PCB build up, glass, mica, Porcelain, plastics and some metal oxides are good dielectrics. The dielectric material will more and more effective with the reduction of dielectric loss the proportion of energy lost as heat.

Comparing to FR-4, rogers material is less likely to demonstrate a dielectric breakdown. Pre-preg can make a good effect on the performance characteristics of the printed circuit board in PCB fabrication. Skype PC. Skype WEB. Sign in.Forums New posts Search forums.

LandLack Member level 3. Hi to all, I've never done a project with pcb, so I know only the basics and some theory.

If I purchase more than one, is there any discount? Isn't this good? If you know anything about any of these questions even if you aren't sureplease reply; I don't want to do it alone with just my theories. Thank you, Best Regards, LandLack. This may help. FR4 is good into the low GHz, is easier to manufacture your boards etc. How many layers are you looking at? I presume two layers of copper. Firstly how tight do you want your impedance tolerances, this really will determine what material to use, contact your PCB manufacturer and discuss this with him.

Secondly cost, how much do you want to pay. I would if doing a commercial product with these frequencies, consult a PCB manufacturer for information on materials, achievable impedance figures etc. Part and Inventory Search.

Dielectric Materials A dielectric material is a substance that is a poor conductor of electricity, and used as an insulating layer in the PCB build up. Porcelain, mica, glass, plastics and some metal oxides are good dielectrics. The lower the dielectric loss, the proportion of energy lost as heat the more effective the dielectric material. If the voltage across a dielectric material becomes too great -- that is, if the electrostatic field becomes too intense -- the material will suddenly begin to conduct current.

This phenomenon is called dielectric breakdown. Rogers is less likely to demonstrate a dielectric breakdown condition than FR Pre-impregnated Pre-preg Contraction of 'pre-impregnated composite fibers', and in the manufacture of PCBs, pre-pregs help influence the performance characteristics of the printed circuit board.

I'm honored to promote this fight. But the bout offers much more to each fighter on a macro level. For Rigondeaux, 37, his professional career has been a constant battle of one step forward and two steps back. Often avoided due to his talent level and lack of marketability, Rigondeaux has typically been his own worst enemy when it comes to business decisions and his reluctance to fight in a style other than cautious.

But a win over Lomachenko would offer Rigondeaux a bookending victory to his career, pairing with his surgical decision win over Nonito Donaire that made his name professionally in 2013. It would also offer Rigondeaux a chance to play spoiler for a second time against his former promoter Arum, who dropped him after his contract expired in 2013.

While you could argue that Lomachenko would benefit more from a commercially satisfying victory to further help build his star, a win over Rigondeaux offers something critically that no other fight can match. And for those who have been slow to anoint Lomachenko so early in his career as one big-name fighter after another as avoided him, this is important.

Power: Both have relied more on speed and accuracy to finish opponents than heavy hands over the years. And even though Rigondeaux likely has more power comparable to his own division than Lomachenko, considering he has a history of having broken the eye sockets of two opponents and the jaw of another, it's hard to overlook he will be moving up two divisions to face Lomachenko.

Rigondeaux has also proven susceptible to flash knockdowns at both 118 and 122 pounds. Speed: It's going to be fun finding out exactly who has the edge. While Rigondeaux is naturally smaller and has long relied on a lightning quick counter left hand, he's also 37 and has been a victim of inactivity. Lomachenko, meanwhile, appeared to shock featherweight Gary Russell Jr. Technique: Just how good are these two from a technical standpoint.

Let it be known, from now until the end of their respective careers, that this is the only time either one will enter a fight without owning a dominant advantage in this category. That's what makes this fight unique to any other. Defense: Part of what makes this matchup so fun is that both are polar opposites in terms of their natural inclinations. Lomachenko is a flashy offensive whiz who uses footwork and awkward angles to break opponents down.

Rigondeaux is more comfortable avoiding punches and exposing his opponent than necessarily making him pay. Like his contemporary Floyd Mayweather, "El Chacal" is in the conversation among the greatest defensive fighters who have ever laced up gloves.

Intangibles: Lomachenko is in the midst of his physical prime at 29 and has been both active and ambitious in his short career, having fought for a world title in his second pro bout. Rigondeaux is a different story. In fact, there are more things going against him than for him in this fight, including age and weight.
