Know What Are Rogers Material PCBs

Rogers Corporation is a well-known manufacturer of laminate materials for PCBs, and Rogers material PCBs are used by many PCB manufacturers and assemblers across the globe. Rogers PCB materials are sold under different brand names depending upon the material used and other features. But, by and large, they are hugely popular among PCB and electronics players because of their robust features. Their Fire Retardant 4 (FR4) material for PCB substrates offers benefits such as a wide range of dielectric constant and decreased signal losses. They offer many other benefits such as improved thermal resistance in harsh application environments. Rogers PCBs are widely used for mission-critical application devices in defense and aerospace. So, what all materials are used in Rogers PCBs and what are their types?

About Rogers PCB Materials and Their Types

Rogers PCB laminate and prepreg materials are of more than at least 15 types. For instance, some materials have exceptional electrical properties, while others offer a high frequency performance. Some are used in microwave and RF applications, while others are used in specific, high-speed or mission-critical applications. Here are a few types widely used by PCB manufacturers.

  • Rogers 4350 materials: These materials are primarily hydrocarbons or woven glass reinforced ceramics. They are processed with compliance to the FR4 standards. Rogers 4350 helps raise the dielectric strength and does not require special tooling or through-hole technology for mounting components like PTFE materials. They are UL 94 V-0 rated for high power RF designs and active devices. They offer an excellent dimensional stability.
  • Rogers 92ML materials: These are halogen-free epoxy prepreg and laminate materials. They are thermally conductive and filled with ceramic. These materials help reduce surface temperature and are environmentally friendly. For PCBs with a metal substrate, these materials are available along with an aluminum plate.
  • RO3000® Series: These materials are widely used in RF and microwave applications. They PTFE composites filled with ceramic, and have excellent electrical and mechanical properties, irrespective of the dielectric constant. They are available with as well as without a woven glass reinforcement. They facilitate multilayer board designs.
Factors to Consider When Choosing a Rogers Material for Your PCB

Being thorough with your application requirements is extremely crucial, especially in case of complex PCB designs. When selecting Rogers PCB materials, you may consider following pointers:

  • Ensure the material does not absorb any moisture when immersed in water. Although this may sound too unreal, the absorption rate should not be more than 0.2%. Materials with low absorption rates will have better thermal and electrical properties.
  • Dielectric constant must be stable in high operating frequency applications. The high value of the charge in a PCB material enhances capacitance and voltage through the PCBs.
  • Things expand when heated and contract when cooled. This simple principle also applies to PCBs when they are exposed to heat beyond the set glass transition temperature. The rate at which they expand beyond this temperature is called the coefficient of thermal expansion and is measured in parts per million (ppm). This is an important factor to check when using Rogers materials.
  • There is always an upper and lower limit to temperature resistance. This is based on the application requirements, and according the materials of PCB are selected. If an error occurs, the temperature is bound to exceed its upper limit and the PCBs may decompose and lose some of their mass. To prevent this, the decomposition temperature should be set beyond this upper limit. Usually, for most applications it is 350 degrees Celsius.

If you are working on a complex project and require multilayered PCBs with a complex design, it is worth using Rogers materials in your PCBs. However, it is important to approach a PCB assembly services provider who is reliable and has plenty of experience designing and assembling complex PCBs. Twisted Traces designs and fabricates Rogers material PCBs and has over 30 years of experience.

We have used Twisted Traces for our prototype assembly for almost 6 years. They are always responsive and complete the job on time with reasonable price. .

Bill

We have been using Twisted Traces for all of our PCB assemblies for over 5 years. The quality of their work is always excellent. They pay close attention to the details, offer fair pricing and always deliver on time. One of the best PCB assembly houses out there..

Adam

I was looking for a quick turnaround assembly Twisted Trace . I must say that I was really happy with the exceptional service and top quality board assembly. I highly recommend Twisted Trace for board assembly . .

Jake

Simply put, Twisted Traces is an excellent resource for anyone needing PCB assembly. They handled all aspects of my build, even the fab process of a very complex 10 layer board. I cannot say enough good things about them. .

John

The best thing to do to save time and money, if you order PCB board and get it shipped to their factory they will start work as soon as everything is there for assembly. They work with you on everything, and make sure its best for you! .

Chris

If you are looking to do some PCB production, this is the place to look into! They are awesome at what they do! .

Jim

I knew absolutely nothing about PCB boards, only that I needed one for the small business I was starting. I called Twisted Traces and they broke down everything I needed to know before we began discussing production possibilities. I am so thankful for them taking their time to explain everything concisely to me. .

Patrick

The quality of the PCB assembly that Twisted Traces provided is very high, and I can fully focus on the performance tweaking of my chip. In the end, it leads to very good results, such as ISSCC, JSSC...etc. If they make a mistake, they are also very fast to compensate the error. .

Daniel
