METHOD OF MANUFACTURING METAL CASE FOR OPTICAL TRANSMISSION AND RECEPTION MODULE PACKAGING

摘要

PURPOSE: A method of manufacturing a metal case for optical transmission and reception module packaging is provided to form an airtight case by using a powder injection method and a sintering method without an additional mechanical process. CONSTITUTION: Iron, nickel, and cobalt powders for composing an ASTM F-15 alloy are mixed uniformly. A feedstock for injection is manufactured by mixing a high molecule binder such as a paraffin wax, polyethylene, and a stearic acid into the mixed powders. An injection mold is manufactured by using the feedstock. The injected molding body is removed by an n-hepthan solution. The remaining binders are removed by a thermal decompression process. A sintering process for the molding body is performed. A nickel plating process and a gold plating process are performed on the sintered body. A glass sealing(2) process is performed. A lid is combined with an upper portion(3) of the metal case.
