Description

Technical Field

[0001] This utility model relates to the field of soldering iron technology, and in particular to an electric soldering iron. Background Technology

[0002] Soldering is a critical process in the manufacturing of electronic products. In the production of electret condenser microphones (ECMs), soldering is widely used due to its flexibility and high precision. Existing soldering irons typically have double-plane or conical tips with a large heating area. This results in the solder melting upon contact with the tip, forming a large hemispherical solder pool, which is difficult to control, thus reducing solder utilization. Furthermore, poor fit with the actual solder pads creates a significant contact distance, requiring extended soldering time to ensure sufficient solder flows onto the surface of the pads. This not only reduces soldering efficiency but can also cause microphone malfunctions due to excessive heating time. Therefore, designing a soldering iron that can effectively solder and melt solder to reduce solder loss and increase soldering speed has become an urgent technical challenge. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technologies and provide an electric soldering iron that can effectively reduce solder loss, increase soldering speed, and avoid quality problems caused by excessive heating time.

[0004] The purpose of this utility model is achieved through the following technical measures: an electric soldering iron, including an electric soldering iron body, a soldering iron tip at the front end of the electric soldering iron body, the soldering iron tip being conical, the front end of the soldering iron tip having a soldering iron tip tip, a heating surface and a solder melting surface on the front side of the soldering iron tip, both the heating surface and the solder melting surface being planar, and the heating surface and the solder melting surface being located on two adjacent 1 / 4 conical surfaces respectively.

[0005] As a further improvement to the above technical solution: The angle between the heating surface and the central axis of the soldering iron tip is 20-30°.

[0006] The angle between the tinned surface and the central axis of the soldering iron tip is 15-25°.

[0007] The length of the line where the heating surface and the tinning surface meet is 1.1-2.3 mm.

[0008] The heating surface and the solder melting surface are respectively connected to the tip of the soldering iron.

[0009] The heating surface is curved on the side away from the tip of the soldering iron.

[0010] The apex of the arc of the heating surface is 1.48-2.1 mm away from the line where the heating surface intersects with the tip of the soldering iron.

[0011] The side of the soldering iron tip away from the soldering iron tip is arc-shaped.

[0012] The apex of the arc of the soldering surface is 1.5-2.4mm away from the junction of the soldering surface and the tip of the soldering iron.

[0013] The soldering iron body has a grip groove on one side.

[0014] Due to the adoption of the above technical solution, the advantages of this utility model compared with the prior art are: 1. Reduced solder loss: The heart-shaped heating surface design effectively limits the size of the molten pool on the heating surface, improving solder utilization.

[0015] 2. Improved soldering speed: The shortened solder flow path and the heating plane design facilitate solder flow, reducing soldering time and improving production efficiency.

[0016] 3. Ensure product quality: Avoid potential quality issues with the microphone caused by excessive heating time.

[0028] The heating surface 5 and the solder melting surface 6 are respectively connected to the tip 4 of the soldering iron.

[0029] The soldering iron body 1 has a grip groove 3 on one side. Example 3

[0030] like Figure 1-8 As shown, an electric soldering iron includes a soldering iron body 1, a soldering tip 2 at the front end of the soldering iron body 1, the soldering tip 2 being conical, the front end of the soldering tip 2 having a soldering tip tip 4, a heating surface 5 and a solder melting surface 6 on the front side of the soldering tip 2, both the heating surface 5 and the solder melting surface 6 being planar, the heating surface 5 and the solder melting surface 6 being located on two adjacent quarter conical surfaces respectively, the angle between the heating surface 5 and the central axis of the soldering tip 2 being 25°, and the angle between the solder melting surface 6 and the central axis of the soldering tip 2 being 20°.

[0034] In use, the heating surface 5 is first brought into contact with the pad to quickly form a fusion surface. The solder wire is then sent to the molten solder surface 6 to quickly form a small molten pool. When the molten pool is saturated, the molten solder flows down and fuses with the pad fusion surface to complete the soldering process.

[0035] Since the heating surface 5 can be in contact with the solder pad, the distance between the soldering iron tip and the solder pad can be significantly shortened, which is conducive to the molten solder flowing to the solder pad melting surface more quickly. In addition, the molten solder surface 6 has a small area and can hold less molten solder, which can reduce solder loss and improve utilization. It can saturate the molten pool more quickly and promote the molten solder to flow to the solder pad. It can effectively avoid quality problems to the microphone caused by excessive heating time.

[0036] The heating surface 5 and the tin-melting surface 6 can be adjusted in angle according to different soldering needs to adapt to different sized pads and soldering process requirements.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
