Description

TECHNICAL FIELD

[0001] The utility model relates to microelectronic package tube shell application technical field, concretely is a segmented type positioning assembly welding fixture suitable for split type kovar surrounding frame. BACKGROUND

[0002] Silver copper brazing is a kind of welding process commonly used to connect metal materials, and is widely used in multiple fields, which mainly utilizes silver-containing solder to weld copper and its alloy at a lower temperature. When silver copper brazing is carried out, flux is usually used to remove the oxides on the surface of the metal and promote the flow and wetting of the solder. Under relatively stable brazing conditions, silver copper solder has good flowability and wettability, and the silver copper solder can well wet the base material during the welding process, forming a strong welded joint, and the silver copper solder is prone to deviation during brazing, resulting in unstable welding.
