This group of packages require careful engineering and choice of materials to meet the varying requirements of the application.
Thermally efficient bases that maintain a
low CTE require the use of specialised materials such as Molybdenum, Molybdenum/Copper
or Tungsten/Copper. These materials bring
their own processing
problems and need specialized handling.
Where weight is an issue our capability includes
the fabrication of
lightweight Metal Matrix bases.
Where ruggedness is required, ceramic insulators
can be used in
place of glass. At TWM Technology
we are experienced in working
with all these options.
