Abstract
A method of producing an LTCC substrate having improved cavity bondability is disclosed that involves providing a stack of green ceramic tape sheets having a cavity, placing a template having an opening corresponding to the cavity over the stack, placing a stretchable sheet of material coated with graphite or zinc stearate over the template, isostatically laminating the stack to produce an LTCC substrate having a cavity, and removing the template and sheet of stretchable material from the stack.
