Panasonic megtron 6 and Rogers 4350B

I am looking for cost and performance comparison between Rogers 4350B and Panasonic Megtron 6. I have read some e-books on Sierra Circuit and also checked online material selector but have not found comparison between Rogers 4350B and Panasonic Megtron 6.

How do we compare the price and performance with FR4 ?

If you look at both datasheets closely, Rogers 4359B might check more boxes for your design when it comes to high-speed performance. For instance, for the dielectric constant, less energy is stored and lost in the dielectric itself. The dissipation factor, copper peel strength, and a few other properties are about the same as Megtron 6.

One thing to know about Rogers is that the material is not made of glass cloth unlike most materials (see image).

Rogers is more uniform and smooth which means there is less loss and variations as the signal travels from the source to the load.

Regarding the price, Rogers would be about 3 times more expensive than Meg 6. Ask your fab house about your design requirements and see if you actually require Rogers.

I have read an article on Sierra Circuits regarding the comparison between Rogers 4350B and Panasonic Megtron 6. This was worth reading article.

I am not sure if I get the “laminate thickness” which is 8 mm in Roger and 18 mm in Megtron 6. Is that core thickness availability ?

Hi Sajal,
Thank you for bringing this to our attention. We have made the necessary modifications to the blog.
The standard thickness for Rogers-4350B ranges from 0.10 mm to 1.52 mm, while the thickness for Panasonic Megtron-6 varies from 0.051 mm to 0.890 mm.


Thanks, Poulomi!

I have read this article and I found it very comprehensive, to the point and well written.
