Abstract

(57) [Summary] [Purpose] To facilitate confirmation of soldering of electronic components on a printed circuit board. [Structure] One pad 3 corresponding to one lead 1 of an electronic component is divided into multiple pads 3 ₁ , 3 ₂ , and the divided pads 3 ₁ , 3 ₂ are connected to one lead 1 at the same time. The tester is connected by soldering and the tester is brought into contact with the divided and adjacent pads 3 ₁ and 3 ₂ without contacting the leads 1 to check the soldering.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a printed circuit board on which electronic components are mounted by soldering.

0002

[Conventional technology]

Traditionally, when mounting electronic components on a printed circuit board, one pad was used for each point. What was expected was normal.

0003 The conventional mounting structure for electronic components on a printed circuit board 16 is as shown in FIG. One pad 13, 14 is prepared for each lead 11, 12 of the product. The pads 13 and 14 were connected to each other by a wiring pattern 15. child When mounting electronic components on the type of printed circuit board 16, each lead of the electronic components is After soldering the pads 11 and 12 to the corresponding pads 13 and 14, When checking the connection, check both leads 11 and 12 and pads 13 and 14 with a tester. I needed to touch it.

0004

[Problem that the idea aims to solve]

With the conventional printed circuit board pads mentioned above, after soldering the mounted electronic components, Test both leads 11 and 12 and pads 13 and 14 when checking the soldered connection. It is necessary to touch the terminal with a terminal to check for poor connections due to unsoldered or insufficient solder. However, the disadvantage was that it was a difficult task.

[0005] An object of the present invention is to provide a printed circuit board that solves the above problems.

[0006]

[Means to solve the problem]

In order to achieve the above object, the printed circuit board according to the present invention has pads. A printed circuit board on which electronic components are mounted through, One pad is a one-to-one solder connection of one lead of an electronic component. and One pad is divided into multiple parts for one lead of an electronic component. be.

[0007] In addition, the pads divided into multiple parts can be simultaneously soldered to one lead of the electronic component. It has a size that allows it to be attached.

[0008] In addition, the adjoining pads divided into multiple parts are used for measuring equipment such as a tester. This is to bring the measured probe into contact with the probe.

[0009]

[Effect]

Separates one pad that is soldered to one lead of an electronic component into multiple pads. This makes it easy to check the soldered connections.

【Example】

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention. In the figure, in this embodiment, one pad 3, 4 to which one lead 11 or 12 of an electronic component is connected by soldering is divided into a plurality of pads (two in this embodiment) on the printed circuit board 6. The sizes of the plurality of divided pads 3 ₁ , 3 ₂ , 4 ₁ , 4 ₂ are set so that they can be soldered to one lead 1 or 2 at the same time. Furthermore, the entirety of the wiring between the pads 3 and 4 is not wired using the wiring pattern 5, but only a part of the pads 3 1 of the two divided pads 3 ₁ , 3 ₂ , 4 ₁ , _{4 2} . and pad 4 ₁ are wired using wiring pattern 5, and the remaining pad 3 ₁ and pad 4 ₂ are electrically disconnected. Under normal conditions, leads 1 and 2 are connected by soldering, but no electrical connection is made. It will be electrically conductive.

0012 In the embodiment, when mounting electronic components on the printed circuit board 6, the electronic parts One lead 1 or 2 of the component is divided into two pads 3₁,3₂or pad 4 ₁ ,4₂are positioned in one-to-one correspondence with each other, and one lead 1 or 2 is Pad 3 divided into pieces₁,3₂set or pad 4₁,4₂Solder each pair of Connecting.

[0013] In order to check the solder connection after soldering the mounted electronic components, a tester is used to measure each pad 3 ₁ , 3 ₂ or pad 4 ₁ , 4 ₂ divided into two parts per lead. This is done by bringing the child into contact. Therefore, connection can be confirmed by touching the probe of the tester to the adjacent pads 3 ₁ , 3 ₂ or pads 4 ₁ , 4 ₂ without touching the leads 1 and 2 of the electronic component.

[0014]

[Effect of the idea]

As explained above, the present invention has multiple mounting parts for electronic components on a printed circuit board. Since the pad is divided into two, it is easy to solder the mounted electronic components. When checking solder connections later, connect the split adjacent pads without touching the leads. This can be done by touching it with a tester, and can prevent connection failures due to unsoldered or insufficient solder. This has the effect of making it easier to check the mounting of electronic components, as well as the mounting of electronic components. Ru.
