What a Dk of 10.2 buys you, where RO6010 is the right answer, and the lamination, drilling and plating practices that keep a ceramic-filled PTFE build on specification.
Rogers 6010, also designated RO6010 or RO6010LM, is a ceramic-filled PTFE laminate with a much higher dielectric constant than the low-loss grades in the same family. That single difference changes what the material is for. A Dk around 10.2 shortens the guided wavelength sharply, which lets a designer fit a given electrical length into a far smaller area, and it makes the material attractive for compact RF and microwave circuits where board space is the constraint. This article covers the specifications, the applications and the manufacturing points that matter.
The headline figures are worth putting in one place. Two of them drive most design decisions: the high Dk is what shrinks the circuit, and the thermal conductivity of 0.66 W/m·K is more than three times that of the low-loss PTFE grades, which is why the material also appears in high-power circuits where heat has to leave the board. The Df of 0.0023 is moderate rather than exceptional, so a design constrained by loss rather than by area should be looking at a low-Dk grade instead, and our comparison of RO3010 versus RO6010 covers that decision in detail.
| Parameter | Value |
|---|---|
| Dielectric constant (Dk) | 10.2 (±0.3) |
| Dissipation factor (Df) | 0.0023 @10 GHz |
| CTE, X and Y axes | 11 ppm/°C |
| CTE, Z axis | 24 ppm/°C |
| Thermal conductivity | 0.66 W/m·K |
| Thickness | 0.010″, 0.020″, 0.050″ and others, tight tolerance |
| Flammability | UL94 V-0 |
The properties point to applications where compact size or power handling outweighs the last fraction of a decibel.
The same family logic applies in our notes on the RT6010LM grade and on the RO3210, both of which share the ceramic-filled approach without identical parameters.
Ceramic-filled PTFE behaves differently from a plain PTFE laminate in a few specific ways, and those differences are what the process has to be built around.
Incoming material is a ceramic-filled PTFE composite, so it should be inspected for scratches and bubbles before it enters the line. Lamination with copper foil runs at high pressure and temperature, and low-expansion press plates are normally used to keep warpage down. The tight thickness tolerance that makes the material useful for RF work is also what makes press control important.
Specialised drill bits are required, with speed and feed chosen to avoid cracking and burring in a material that is more brittle than standard PTFE. The other difficulty is adhesion: the surface of RO6010 is smooth and chemically inert, so holes need plasma activation before plating or copper will not bond reliably to the wall.
Etching has to produce fine circuit patterns without over-etching, because removing too much dielectric changes the electrical performance the design depends on. Post-production testing focuses on dielectric constant, signal loss and thermal behaviour. Quality control follows ISO9001 as a baseline, with military or aerospace standards layered on where the application requires it. Because the material is brittle, packaging must be anti-static and shock-proof, and it has to protect against moisture during transit.
RO6010 earns its place when the circuit has to be small or has to handle power, and the loss budget has room to give. That covers compact radar and satellite front ends, defence electronics, avionics modules and instrumentation. Where the requirement is instead the lowest possible attenuation across a wide band, a low-Dk PTFE grade such as the 5880 is the better tool, and the two are not really substitutes. Choosing between them is a question of which constraint binds first, and our material notes aim to make that comparison concrete rather than theoretical.
Frequently Asked Questions
It is a ceramic-filled PTFE composite, and the ceramic load raises Dk to around 10.2. That is a deliberate trade: a higher Dk shortens the guided wavelength, so a given electrical length occupies far less board area.
Its Df of 0.0023 is moderate rather than exceptional. That is acceptable when compact size or power handling is the binding constraint, but a loss-limited design should use a low-Dk grade such as the 5880 instead.
Because the material is a smooth, chemically inert PTFE composite. Without activation, copper does not bond reliably to the hole wall, and adhesion failures show up later as intermittent opens.
It is more brittle. Standard speeds and feeds tend to crack or burr the material, so the process needs specialised bits and tighter control to keep hole quality acceptable.
As brittle, moisture-sensitive parts. Anti-static and shock-proof packaging protects against impact and humidity in transit, and the boards should not be exposed to unnecessary mechanical stress.
