Mega Industries utilizes a small vacuum furnace for product development and small production runs of UHV brazed components. With this furnace, Mega can speed up brazing development time by precise control of temperature profiles in conjunction with four additional survey thermocouples to monitor localized temperature conditions. Mega has developed brazing expertise in making various metal to metal bonds as well as metalized ceramic bonds required to manufacture sophisticated structures for its customers.
The furnace has a unique feature in that its 8″ dia. x 12″ deep working heat zone can be oriented either horizontal or vertical. This allows for a small chamber to heat zone ratio that facilitates pump down time and minimizes gas bleeding volume. The furnace is capable of ambient to 2,400 °F and can braze from atmosphere to high vacuum (10-6 torr).
Ultra High Vacuum (UHV) Products
Mega Industries produces an array of Ultra High Vacuum (UHV) compatible waveguide and coaxial components that are custom tailored to provide the high electrical performance in the Ultra High vacuum environment down to 1 x 10-12 Torr. That means all of these components are constructed using vacuum rated materials such as OFHC copper, non-magnetic stainless steel (304, 316L & 316LN), and ceramics such as alumina, sapphire and quartz. Our manufacturing process uses advanced vacuum brazing techniques, and all components are cleaned, assembled and tested in our clean room facility.
Mega can test and verify many vacuum properties such as vacuum He leak rates down to 5.0 x 10-12 Torr l/s, and internal outgassing levels to 1.0 x 10-12 Torr l/s cm2 to deliver “UHV” clean components that can easily be integrated into your systems. Mega will perform bake out procedures and unique vacuum packaging protocols to insure the components to be in a “vacuum ready” state.
Mega has designed and constructed many UHV waveguide and coaxial components to date, each with unique characteristics and properties. Please examine the array of devices Mega’s vacuum experience has developed. We look forward to working with you.
