Kevin, Received and tested the boards - thanks very much. These are perfect, exactly what we needed. rgds Rich

—— Rich Rickett

Ruth, I got the PCB today, and they are just perfect. Please stay a little patience, my next order is coming soon. Kind regards from Hamburg Olaf

—— Olaf Kühnhold

Hi Natalie. It was perfect, I attach some pictures for your reference. And I send you next 2 projects to budget. Thanks a lot again

—— Sebastian Toplisek

Kevin, Thanks, they were perfectly made, and work well. As promised, here are the links for my latest project, using the PCBs you manufactured for me: Regards, Daniel

(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)


RO4350B hydrocarbon ceramic laminates are designed to offer superior high frequency performance and low cost circuit fabrication. The selection of laminates typically available to designers is significantly reduced once operational frequencies increase to 500 MHz and above. RO4350B material possesses the properties needed by designers of RF microwave circuits and matching networks and controlled impedance transmission lines. Low dielectric loss allows RO4350B material to be used in many applications where higher operating frequencies limit the use of conventional circuit board materials.


The temperature coefficient of dielectric constant is among the lowest of any circuit board material, and the dielectric constant is stable over a broad frequency range. RO4350B material's thermal coefficient of expansion(CTE) provides several key benefits to the PCB designers. The expansion coefficient of RO4350B is similar to that of copper which allows the material to exhibit excellent dimensional stability, a property needed for mixed dielectric multi-layer boards constructions. The low Z-axis CTE of RO4350B provides reliable plated through-hole quality, even in severe thermal shock applications. RO4350B material has a Tg of >280C so its expansion characteristics remain stable over the entire range of PCB processing temperatures.
