CQFPs are hermetic packages consisting of true pieces of dry pressed ceramic surrounding a uniformed leadframe with tie bar attached. Lead counts for this package range from 14 to 304, with lead pitch ranging from 15.7mil to 50mils. Package leads are gold or Kovar finish and can be solder-coated by special request. The lids are optional for CQFPs, which are sealed over the package cavity at temperatures from 400° to 460° C.
