The chrome plated tungsten rods are used for thin films of chromium in the electronics and optics industries. The advantage of using chrome rods over chrome chips are better thermal efficiency, regulation of film thickness and elimination of spitting and spalling which can cause pinhole type defects.

Our Micro-Electronic sources represent a full line of smaller size sources that are similar to the standard size sources in our catalog. The overall length on these sources is slightly less than 2 inches, in most cases. The smaller sources are ideal for lower power systems or processes that require small amounts of evaporants. Images shown are for reference only. Actual parts may look different based on the type of wire selected. Wire types available for each part are shown in the suffix of the part number. For example, ME11-.030W is made with a single strand of .030" diameter tungsten wire. ME11-3x.025W is made with 3 strands od .025" diameter tungsten wire, twisted together.

Shielded Crucible Heaters provide uniform heating to the installed crucible and allow very high rates as well as high temperatures, up to 1800°C, to be achieved. Due to the rigid construction, heater and crucible life is extended. The thermal shields protect your components by reducing the radiant heat that your system is exposed to. Custom sizes are available on request. Please contact our technical staff if you would like more information about these products.

The R.D. Mathis Company offers a wide selection of High Purity, Vacuum Ready Evaporation Materials. Gold, Silver, Nickel, Aluminum, Germanium, Titanium, etc. are available in small pellet sizes, slugs, wire, rod, sheet or plate. These and other vacuum materials are available in a variety of purities, sizes and quantities. We also offer hard to find evaporation materials as well as well as the ability to offer you custom alloys to meet your specific vacuum coating needs. Keep checking our website for new materials and updated pricing. We are continuing to expand our range of vacuum ready evaporation materials, if you do not see the material you are looking for, please contact our sales staff for availability and pricing. Please view the items below to see our current selection of evaporation materials. In most cases, the part numbers of the evaporation materials below also describes some characteristics of the material. For example, PN AL59X88-100G indicates the material is Aluminum (AL), the purity is 99.999X% (59X), the pellet size is 18” x 18” (88) and the quantity is 100 grams (100G)

The R. D. Mathis Company “Baffled Box” Silicon Monoxide Source, SiO source, has proven to be an extremely successful method of depositing Silicon Monoxide. Source material is positioned in the boat within separate cavities, when heated it follows an indirect path through a series of baffles and then out of the exhaust chimney. The substrate cannot see the bulk material at any time. This essentially eliminates any chance of spitting and streaming which causes pinhole type defects. Many of the sources shown are available with up, down or horizontal exhaust ports. Custom fabrication and larger volume sources to fit your specific process needs are available upon request. A paper describing the techniques of Silicon Monoxide deposition and results using the “Baffled Box Source” is available upon request…ask for “Silicon Monoxide Evaporation with the Multi-baffled Box Source” by Earl Olson of the Halex Corp. and R. D. Mathis.
