The invention relates to a shell for packaging a
microwave assembly and a
laser sealing method of the shell. The shell for packaging the
microwave assembly comprises an aluminum
silicon alloy shell and a 4047 aluminum
alloy cover plate, wherein the aluminum
silicon alloy shell is abutted with the 4047 aluminum alloy cover plate. The
laser sealing method comprises the following steps of: cleaning the aluminum
silicon alloy shell and the 4047 aluminum alloy cover plate by using
acetone, then abutting the aluminum
silicon alloy shell with the 4047 aluminum alloy cover plate by using a tool, then fixing the aluminum
silicon alloy shell and the 4047 aluminum alloy cover plate by using an Nd:YAG
laser, and continuously integrally
welding the shell by using the Nd-YAG laser,
welding from the bottom of the aluminum
silicon alloy shell until reaching the surface of the 4047 aluminum alloy cover plate, wherein the two
welding processes are carried out in a
nitrogen protective gas. The invention is used for carrying out sealing by using the laser, is easy to realize, has good sealing property and controllable welding depth, can be used for repaired for two times, has little
thermal impact to a substrate and a
chip because local heating is adopted in the
welding process, can realize automatic operation, and has no
soldering flux
pollution and high reliability.
