A kind of production and processing technology of optical module shell

Abstract

A producing and processing technology for an optical module shell includes the steps that die-cast formation is conducted on the optical module shell through a zinc alloy, and surface nickel plating is conducted, wherein the thickness of a cover plate ranges from 0.4 mm to 0.55 mm, and the thickness of a base ranges from 0.6 mm to 0.8 mm; oxide and impurities on the surface of the cover plate and the surface of the base are removed; the base is placed in a clamp, and the space between the base and the cover plate is coated with soldering flux, wherein the thickness is 0.02 mm; the cover plate is placed on the base without dislocation; the cover plate is pressed downwards with force so that the cover plate, the soldering flux and the base can make close contact; the residual soldering flux is wiped off, and cleanness is kept; it is ensured that the surface of a seam welding electrode is clean and dry; the inner hole wall of the seam welding electrode is coated with conductive grease with the thickness being 0.02 mm, the seam welding electrode is installed on a parallel seam welding machine in the manner that the seam welding electrode can slightly rotate, and the whole seam welding electrode is kept clean; one point is formed at the position of the contact center of cover plate and the base through seam welding, the seam welding electrode is moved to the rightmost end or the leftmost end, and seam welding is started; and a qualified product is obtained. The producing and processing technology solves the problems that the production cost of the optical module shell is high and during packaging, the gas tightness and firmness are poor and a clad layer is damaged.
