Despatch offers a wide selection of high performance ovens for annealing. The portfolio of annealing ovens offers
a variety of chamber sizes and temperature capabilities to best for any customer’s application. These ovens feature
exceptional temperature uniformity, flexibility and tight process control and monitoring.
Custom Annealing Ovens
Despatch’s custom magnetic annealing tools are used for magnetic annealing processes required to manufacture recording heads for the data storage industry and MRAM devices for semiconductor applications.
Used by companies around the world, these tools offer the best overall throughput in the industry, by combining large load capability with uniform temperature ramp-up and cool-down rates. The product features a wide range of field strength options, including electromagnets up to 1.0 Tesla. Tight temperature uniformity of +/- 0.5°C across each wafer and within the wafer stack maximize product yield. An aluminum brazed chamber provides even wafer heating which is critical to the success of the magnetic annealing process. Additionally, our tools can have temperatures up to 300°C, and magnetic fields up to 1.0 Tesla.
Despatch’s Magnetic Annealing Tool offers flexibility to recording head process designers. With a wide range of temperatures, magnetic field strengths, wafer rotation, and a variety of material handling options, Despatch’s tools enable head manufacturers to keep pace with rapidly changing technology.

Despatch designed and built a custom FCH2-12 furnace for a special component annealing application. Per the
customer’s request, the FCH incorporated HEPA filtration of fresh air and a 316L interior for improved chamber
cleanliness. Other features included modulating dampers on the fresh air and exhaust to
allow a controlled cooling rate and a large forced exhaust fan to promote rapid cooling
after a cycle. A Watlow F4 controller with WatView software was provided to support a
variety of cycle profiles with a highly flexible profiling controller.
The FCH2-12 furnace is available with standard design features including 1350°F (732°C)
maximum temperature rating, 7 inches of layered insulation, 304 stainless steel fully
welded interior, horizontal airflow with adjustable supply and return louvers and a 5 HP
recirculation drive motor. The oven is capable of temperature uniformity of ±1% or better
after stabilization. This oven is compatible with a variety of high temperature processes.
