Monolithic ltcc seal frame and lid

A method for forming a monolithic seal frame and lid for use with a substrate and electronic circuitry, the method comprising the steps of:

• forming a mandrel from a ceramic and glass based material, the mandrel having roughly the same footprint as the electronic circuitry with roughly the same length and width as the electronic circuitry;
• coating at least a portion of the upper surface of the mandrel with a high-temperature lubricant;
• forming a seal frame and lid block from a ceramic and glass based material;
• forming a seal frame and lid by routing ceramic and glass based material from the seal frame and lid block to create a compartment and at least one sidewall;
• placing the seal frame and lid on the mandrel such that the mandrel fits within the compartment;
• cofiring the seal frame and lid;
• and
• coating at least a portion of the seal frame and lid with a layer of metal.

A method for forming a monolithic seal frame and lid for use with a substrate and electronic circuitry, the method comprising the steps of:

• forming a plurality of mandrels 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 removing the ceramic and glass based material from the seal frame and lid block to form at least one sidewall, a plurality of compartments, and at least one divider wall;
• placing the seal frame and lid on the mandrels such that one mandrel fits within each compartment;
• and
• cofiring the seal frame and lid.
