Monolithic LTCC seal frame and lid

DWPI Title: Forming method for monolithic seal frame and lid for use with substrate and electronic circuitry involves placing seal frame and lid on mandrel such that mandrel fits within compartment, and cofiring seal frame and lid
Abstract: A method for forming a monolithic seal frame and lid for use with a substrate and electronic circuitry comprises the steps of forming a mandrel from a ceramic and glass based material, forming a seal frame and lid block from a ceramic and glass based material, creating a seal frame and lid by forming a compartment and a plurality of sidewalls in the seal frame and lid block, placing the seal frame and lid on the mandrel such that the mandrel fits within the compartment, and cofiring the seal frame and lid block.
Use: Forming method for monolithic seal frame and lid (claimed) for use with substrate and electronic circuitry.
Advantage: Allows the seal frame and lid to be constructed using additive material manufacturing processes that generate the seal frame and lid from ceramic stock material.
Novelty: The forming method involves forming mandrel from a ceramic and glass based material, and forming a seal frame (18) and lid (20) block from ceramic or ceramic and glass based material. The seal frame and lid (16) is created by forming a compartment and at least one sidewall in the seal frame and lid block. The seal frame and lid is placed on the mandrel such that the mandrel fits within the compartment, and the seal frame and lid is cofired. The mandrel is formed to have roughly the same footprint as the electronic circuitry (14).
