Patent ID: 7416630

Claim:
A method of fabricating a package for an electronic device with low temperature co-fired ceramic (LTCC) including one or more multi-layer parts having multiple cavities therein for the location of active and passive electronic circuit components, comprising the steps of: dividing and stacking a plurality of partially fabricated layers of LTCC material into a predetermined number of stacks, each of the stacks including a predetermined number of LTCC layers based on a respective cavity configuration to be subsequently formed therein; separately laminating each of the stacks of LTCC layers at a first predetermined pressure into individual sections of laminated LTCC material; forming desired cavity patterns into each of said sections; stacking the sections including the cavity patterns formed therein into an assembly of contiguous sections; placing the assembly in a lamination fixture; and isostatically laminating the assembly of the sections at a second predetermined pressure into a composite LTCC structure; wherein said layers of LTCC tape comprise at least 20 layers of about 5 mil thick tape.
