Combo Rectangular Lids

Combo lids™ are Kovar or Alloy 42 base material with multilayer gold and nickel plating per MIL-M-38510. The Preform is 80/20 Gold/Tin alloy with a standard thickness of .0021″. The lid thickness is .010”-.015”. For the best seal, the Lid OD should be .025″ less than the package seal ring OD and the Lid ID should be .045″ larger than the package seal ring ID, provided a minimum solder width of .025″ is maintained.
