Abstract

The invention relates to a welding process used for a passive device. The passive device comprises a box body and a waterproof cover plate encapsulated on the box body. The welding process used for the passive device comprises the following steps: printing mixed tin paste at a joint of the box body and the waterproof cover plate by use of a steel mesh; mounting the waterproof cover plate on the box body, and clamping the waterproof cover plate on the box body by use of a tool clamp; and putting the passive device into a reflux soldering furnace to sequentially carry out pre-heating, heating, heat-preserving and cooling. According to the welding process, the passive device is input into the reflux soldering furnace to sequentially carry out pre-heating, heating, heat-preserving and cooling, so that tin powder in the tin paste is molten, and soldering flux slowly volatilizes to form a welding seam which is continuous and compact, and is high in welding strength, and therefore, waterproof and gastight requirements are achieved. Meanwhile, the production cost is reduced, the thinning treatment of the wall thickness of the passive device is facilitated, and batched automatic production is easy to realize.

Description

technical field [0001] The invention relates to welding process technology, in particular to a welding process for passive devices. Background technique [0002] At present, passive devices are installed by adding waterproof sealing rings, and then using screw locking to achieve the technical effect of waterproofing and conductivity. However, using the above method to install the waterproof cover has at least the following disadvantages: 1. The conductive waterproof sealing ring leads to an increase in cost; 2. The wall thickness at the place where the waterproof sealing ring is installed cannot be thinned; 3. The waterproof sealing ring Installation is a manual operation, and it is difficult to realize batch automatic production. 4. The waterproof sealing ring will age with the influence of environmental changes and time growth, resulting in failure. Contents of the invention [0003] Based on this, it is necessary to address the above problems and provide a welding pro...
