Abstract
The utility model provides a PCB circuit structure convenient for jumper connection, which comprises two bonding pads, wherein the two bonding pads are arranged on a PCB, the two bonding pads are adjacently arranged, the adjacent side edges of the two bonding pads are parallelly arranged to form an insulation gap, and the side edge of the two bonding pads, which is far away from each other, is arc-shaped. The beneficial effects of the utility model are as follows: the success rate of the short circuit of the bonding pad on the PCB is improved.
Description
Technical Field
The utility model relates to the field of electricity, in particular to a PCB (printed circuit board), and particularly relates to a PCB circuit structure convenient for jumper connection.
Background
In the manufacture and repair of electronic devices, jumpers are often required to connect different electronic components on a circuit board, for testing during development, for specification selection during production, etc. The traditional PCB jumper connection mode adopts a packaging connection mode of resistors or capacitors on a PCB, as shown in fig. 1, as the resistors or capacitors on the PCB are welded by the square bonding pads 20, the square bonding pads 20 are difficult to be shorted together by molten tin in actual operation, in particular, when tin liquid falls on the square bonding pads 20, the tin liquid can be diffused due to the property of the liquid, because no special constraint structure exists, the diffused and solidified tin liquid is difficult to cause the shorting of the two square bonding pads 20 to be successful, and soldering is required to be performed again, so that the PCB jumper connection device is very unfriendly to novice, and the square bonding pads 20 can be shorted successfully only by multiple times and long-time exercises, so that the working efficiency is very affected.
Disclosure of utility model
The utility model aims to provide a PCB circuit structure convenient for jumper connection, which aims to solve the technical problem of low success rate of using tin liquor for short circuit of the conventional square bonding pad in the prior art.
In order to achieve the above object, the present utility model provides the following technical solutions:
The utility model provides a PCB board circuit structure convenient to jumper wire is connected, includes two pads, two the pad sets up on a PCB board, two the adjacent setting of pad, two the adjacent side parallel arrangement of pad forms an insulating gap, two the side that the pad is far away is the arc.
Further, the two sides of the bonding pads and the extension line are surrounded to form an ellipse.
Working principle:
The outer edges of the two bonding pads are changed into arc shapes, so that the two bonding pads form an ellipse on the whole, when molten tin is dripped, the ellipse outline enables the surface tension of molten tin to be larger, and a vault-shaped welding spot with radian on the surface is formed.
Compared with the prior art, the utility model has the beneficial effects that: the success rate of the short circuit of the bonding pad on the PCB is improved.

Fig. 1 is a schematic diagram of a bonding pad of a conventional PCB board.
Fig. 2 is a schematic structural diagram of a circuit structure of a PCB board for facilitating jumper connection according to the present utility model.
In the figure, 10 is a circuit on a PCB board.
Detailed Description
The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model and the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1
Referring to fig. 1 and 2, the present utility model provides a technical solution:
The utility model provides a PCB board circuit structure convenient to jumper wire is connected, includes two pad 1, and two pad 1 set up on a PCB board, and two pad 1 adjacent settings, two adjacent side parallel arrangement of pad 1 form an insulating gap, and two pad 1 are the arc apart from the side that is far away.
Further, the sides of the two pads 1 and the extension line are surrounded to form an ellipse.
The working process comprises the following steps:
on the PCB, two bonding pads 1 are respectively connected with connecting wires needing short circuit. The soldering iron head is used for soldering the two bonding pads 1, molten tin diffuses along the two bonding pads 1 after melting, the outer edges of the bonding pads 1 are arc-shaped, the whole outline is elliptical, molten tin liquid drops on the two bonding pads 1 easily break through an insulation gap and are converged to form an elliptical drop, the elliptical outline enables the surface tension of molten tin to be larger after melting, the molten tin is easily separated from the soldering iron head, and the molten tin forms a vault-shaped welding spot with radian on the surface, so that the connection of the two bonding pads 1 is realized.
