Latest Patents

Hilmar W Spieth holds a patent for a "Reworkable die attachment." This invention allows an integrated circuit to be reworkably attached to a circuit board, forming a compliant bond that remains stable under high thermal stress and thermal coefficient of expansion mismatch. The process involves using a thermoplastic adhesive with a melting temperature higher than the integrated circuit's operating temperature, which is coated on the integrated circuit and dried. The adhesive is then cured, allowing the integrated circuit to be bonded to the circuit board with a thermosetting epoxy that has a low curing temperature. This innovative method ensures that the circuit board is not damaged during the curing process and allows for easy removal of the integrated circuit when needed.
