With over 62 years of working with refractory metals, we can fabricate a wide range of parts designed for use in the vacuum deposition process.
Although we primarily manufacture parts for thermal evaporation, we also offer other vacuum components including: evaporation materials, electrodes, e-beam filaments & liners, heat shields, sputtering targets, and more.
R.D. Mathis Company sources 100% of its material from well-known US suppliers. Fabrication is all performed in our California facility. Our material vendors process their ore in the US, and this helps build our resilient supply chain.
When designing a thermal evaporation process, you need to know if your power supply can handle resistively heating a source — this information can be found in our power requirement table.
How do I use this table? Do these values represent maximum rated temperatures?
NO: This table shows the amperage needed to reach a specific temperature. These are based on experimental results and can vary, but it acts as a solid baseline estimate.
These are current-driven components. Thermal output is changed by adjusting the amperage by the same percent as the temperature.
Example:
S1-.005W Boat
101 Amps, 1800°C
To reach 90% of the temperature (≈1600°C), the current would be 101 Amps * 90%, or about 91 Amps.
This table, and other R.D. Mathis Company publications, can be publicly found by accessing our technical library.
