Problems solved by technology

[0002] Most of the low-sensitivity busbars produced in the past are flat and cannot make full use of the limited space, which seriously restricts the application range of low-sensitivity busbars; if it is necessary to manufacture three-dimensional low-sensitivity busbars, special molds must be opened, and the production cycle Long, high production costs, so uneconomical, difficult to commercialize

Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] Referring to the accompanying drawings, this embodiment is a three-fold low-sensitivity busbar. Between the upper polyimide film insulating layer 1 and the middle polyimide film insulating layer 3 is the negative busbar 2 (that is, the copper plate conductive layer 2), and between the middle polyimide film insulating layer 3 and the lower polyimide film Between the amine film insulating layers 5 is the positive busbar 6 (that is, the copper plate conductive layer 6); an insulating pad 7 is installed at some openings of the busbar; copper sleeves 4 are riveted at the remaining openings of the busbar.

[0015] Its manufacturing process includes the following steps: (1) punching the copper plate; (2) bending the punched copper plate into the shape shown in the figure; (3) deburring; (4) tinning; (5) cleaning; (6) Lamination Laminate the copper bar that has been manufac...

Abstract

This invention discloses a 3-D low inductance parent row and its manufacturing method. This parent row chooses polyimide film with acrylic acid glue on one side as the insulation layer, the acrylic acid glue as the sticker; add insulation pad on at least one open-aperture of the parent row; rivet bronze sheathes on other open-apertures of the parent row, or open deep aperture on the row. The manufacturing method includes the following processes: (1) bronze plate punching; (2) curving; (3) trimming; (4) surface process; (5) cleaning; (6) lamination. The advantages are good use of space position, thin insulation layer, low inductance and small resistance.

Description

technical field [0001] The invention relates to a three-dimensional low-sensitivity busbar and a manufacturing method thereof, in particular to a three-dimensional special-shaped low-sensitivity busbar and a manufacturing method thereof. Background technique [0002] Most of the low-sensitivity busbars produced in the past are flat, which cannot make full use of the limited space, which seriously restricts the application range of low-sensitivity busbars; if it is necessary to manufacture three-dimensional low-sensitivity busbars, special molds must be opened, and the production cycle Long, high production costs, so very uneconomical, difficult to commercialize. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects of the prior art, and provide a three-dimensional low-inductance busbar with short production cycle and low production cost and a manufacturing method...
