Abstract

Soldering iron tips to which roller is attached are provided to remove parts easily and extend service life of the tips by closely adhering rollers to pins of parts, thereby uniformly transferring heat of a heater and reducing the friction when contacting soldering iron tips with the pins. In a soldering iron tip(10) for transferring heat to the pin by contacting with each pin of an electronic part, the soldering iron tip comprises a roller(11) fixed and connected, by a steel wire(12) or the like, to one end of the soldering iron tip that comes in contact with each pin. The roller is inserted into a groove formed on one end of the soldering iron tip, and the soldering iron tip and the roller are fixed and connected by the steel wire. The roller is inserted into a steel wire fixing hole formed in the soldering iron tip, the roller is connected to the soldering iron tip by the steel wire, ends of the steel wire are inserted and fixed into the steel wire fixing hole of the soldering iron tip by bolts.

The present invention relates to a pharyngeal tip of the pharynx.

When attaching components to a PCB, the solder may be melted and soldered pin by pin.

After that, when the parts need to be removed due to breakdown, etc.

For simplicity, there is a product that can be used by replacing only the iron tip.

The tip of the iron tip has a variety of shapes depending on the shape of the electronic component.

Surface mount components include SOP, QFP, and PLCC.

The present invention relates to a conventional iron tip of the fixed shape as shown in FIG. There is a phenomenon that the circuit pattern on the PCB is broken by transmission.

Accordingly, the present invention provides an iron tip having an improved structure so that the heat of the heater is transferred to the iron tip and back to the roller to evenly transmit the part in contact with the part and to reduce the friction on contact to extend the life of the tip. have.

In order to achieve the above object, the iron tip with a roller according to the present invention is

It is characterized by connecting with a steel wire to attach the roller to the tip end.

Hereinafter, the iron tip to which the roller is attached will be described in detail with reference to the accompanying drawings.

In general, a soldering iron widely used for soldering consists of a soldering iron tip, a heater and a temperature control device.

The iron tip functions to conduct the high heat of the heater to melt the lead and seat the molten lead on the portion to be soldered.

It can also be used to remove parts already soldered onto the PCB board, depending on the shape of the part.

This tip is also known as a desoldering iron tip,

It is made of copper or copper alloy material with high thermal conductivity, and the iron tip surface is plated with metal materials such as iron and chromium in order to suppress erosion caused by lead.

Since the iron tip with a roller according to the embodiment of the present invention is characterized in that the iron tip structure, a description will be made below with reference to the iron tip only.

1 is a view showing a typical iron tip.

2 is a view showing the structure of the iron tip 10 with a roller according to an embodiment of the present invention.

As shown in FIG. 2, the iron tip 10 has a groove formed at one end thereof to insert the roller 11, and the iron tip 10 and the roller 11 are fixedly connected to the steel wire 12.

The roller 11 can reduce the friction when contacting each pin of the electronic component to extend the life of the iron tip and can easily transfer the high heat of the heater through close contact with each pin of the component can facilitate the operation.

The shape of the iron tip shown in FIG. 2 corresponds to the SOP shape, which is a kind of electronic component, and faces each other, and may be subdivided into several pieces according to the size of the component.

 In addition, depending on the shape of the electronic component, in the case of QFP, PLCC, etc., four rollers may be formed in a square.

Figure 3 shows an enlarged middle section of the roller portion of the roller has a center hole and a steel wire passes through, the steel wire is fixed to the iron tip is a structure that can be rotated without hanging the roller falling.

Figure 4 is a view showing another embodiment of the iron tip with a roller of the present invention

Instead of making a groove in one end of the iron tip 10, a hole for fixing the steel wire 12 to the iron tip 10 is connected to the roller 11 by the steel wire 12, and the end of the steel wire 12 is the iron tip 10. Insert it into the fixing hole of the wire and use it so that it does not fall out. The end of the steel wire 12 can be fixed with a bolt.

Iron tip with a roller according to an embodiment of the present invention has the effect that can be evenly transmitted to all the pins of the heater heat when removing the electronic components on the PCB board.

The present invention has been described above with reference to the preferred embodiments, which are merely examples and are not intended to limit the present invention, and those skilled in the art to which the present invention pertains do not depart from the essential characteristics of the present invention. It will be appreciated that various modifications and applications are not possible that are not illustrated above. For example, each component specifically shown in the embodiment of the present invention can be modified. And differences relating to such modifications and applications will have to be construed as being included in the scope of the invention defined in the appended claims.

Using the iron tip attached to the roller according to the present invention has an effect that can easily transfer the heater heat evenly to all the pins of the component when removing the electronic component on the PCB board.

Claims (1)

In the iron tip that transmits heat in contact with each pin of the electronic component, An iron tip comprising a roller fixedly connected to one end of the iron tip in contact with each pin.
