Embodiment 1

[0034] The printed circuit board 5 of the present embodiment uses a bus sheet, such as figure 1 As shown, it includes a bus body 1 , a raised portion 2 , a potting glue layer, a printed circuit board 5 and a heating electronic component 6 integrated on the printed circuit board 5 .

[0035] Wherein, the main body 1 of the busbar is a plate-shaped structure bonded and connected to the back of the printed circuit board 5, and a potting glue layer for fixing the two together is provided between it and the printed circuit board 5, and the printed circuit board 5 The heat generated is conducted to the main body 1 of the busbar through the potting adhesive layer. Since the main body 1 of the busbar is generally made of metal, its thermal conductivity and heat dissipation performance are better than those of the printed circuit board 5, and the heat generated by the printed circuit board 5 can be dissipated. Prevent the printed circuit board 5 from overheating and damaging electronic...

Embodiment 2

[0047] The printed circuit board 5 of this embodiment includes the bus sheet for the printed circuit board described in the first embodiment, and also includes the printed circuit board 5 .

[0048] Such as Figure 5 As shown, in use, the printed circuit board 5 is arranged in the installation case 11, and the installation section 11 is used to protect the printed circuit board 5 and prevent accidental touch.

Abstract

The invention relates to the technical field of printed circuit board manufacturing, in particular to a busbar for a printed circuit board and a printed circuit board. Connected, the raised part is set on the main body of the busbar, and the printed circuit board is provided with a socket connected with the raised part, and the socket extends to the copper foil layer of the printed circuit board, and the raised part is connected to the copper foil layer Pass. The bus sheet of the invention has the advantages of simple installation process and good competitiveness, and can integrate heating electronic components on the printed circuit board, so that the printed circuit board tends to be more miniaturized and high-density.

Description

technical field [0001] The invention relates to the technical field of printed circuit board manufacturing, in particular to a bus sheet for a printed circuit board and a printed circuit board. Background technique [0002] Printed circuit board, also known as printed circuit board, the English name is PCB (Printed Circuit Board), which is the support of electronic components and the carrier of electronic connection of electronic components. Its design is mainly layout design. The main advantages of using circuit boards It greatly reduces the errors of wiring and assembly, and improves the automation level and production labor rate. When the flow current of the printed circuit board reaches more than 100A, it usually costs more to rely on the printed circuit board to guide the current, so it is necessary to use the busbar to guide the large current of the printed circuit board. [0003] In the installation process of the busbar in the prior art, it is necessary to expose th...
