Problems solved by technology

Before the packaging process, the magnetron will be exhausted, and the traditional soldering is used to exhaust before welding. The degassing is not complete, which will make it difficult to achieve a higher vacuum degree; secondly, the weld seam is required after solder welding It is smooth and uniform without gaps, but in some places with large weld areas, it is difficult to ensure that large-area welds can be smooth and uniform without empty spots; The problem of impenetrable welding

Embodiment Construction

[0017] The present invention will be specifically described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the present invention provides a special-shaped soldering sheet, which is an annular sheet 1 on which uneven pits 2 are distributed. The uneven pits 2 are evenly distributed along the circumference of the annular sheet 1 . The uneven pits 2 are convex pits and pits distributed alternately, respectively as figure 2 and image 3 shown. The included angle between the center points of two adjacent uneven pits 2 and the center of the ring-shaped sheet is 60°. The distance between the center points of two opposite uneven pits 2 is 13-20mm. The depth of the uneven pit 2 is 0.12 to 0.18mm; the depth is the distance from the upper surface of the annular sheet to the lower surface of the pit, that is figure 2 and image 3 The vertical distance between the topmost and bottommost in .

[0019] Preferably, the uneven pit 2 is a circu...

Abstract

The invention discloses an irregular soldering flake which is an annular sheet, wherein uneven pits are formed in the annular sheet; the uneven pits are uniformly distributed along the circumference of the annular sheet; the uneven pits are convex pits and concave pits which are distributed alternatively. As the shape and the size of the soldering flake are meticulously designed, the soldering flake can be applied to special situations such as large-area soldering and irregular soldering.

Description

technical field [0001] The invention relates to the technical field of solder, in particular to a solder piece with a specific shape. Background technique [0002] In the field of electric vacuum devices, there are special requirements for the vacuum degree of vacuum welding devices. Before the packaging process, the magnetron will be exhausted, and the traditional soldering is used to exhaust before welding. The degassing is not complete, which will make it difficult to achieve a higher vacuum degree; secondly, the weld seam is required after solder welding It is smooth and uniform without gaps, but in some places with large weld areas, it is difficult to ensure that large-area welds can be smooth and uniform without empty spots; To, impenetrable problems. Contents of the invention [0003] To solve the above-mentioned problems in the prior art, the applicant provides a special-shaped soldering sheet. The shape and size of this soldering piece have been carefully desig...
