왜 is the 전기 납땜 iron's 납땜 와이어 not sticky?
그만큼 전기 납땜 철 is an essential tool for every electronic DIY enthusiast and home appliance maintenance personnel. The most common problem that 발생 during use is that the soldering iron tip does not eat tin. for this problem, many friends don't know what caused it to not eat tin, and they don't know how to fix it.
소개 및 작업 원리 의 전기 납땜 철
The electric soldering iron is mainly composed of a handle, a power cord, a heating core, a soldering iron head, and a mica sheet (some precision ones also have various temperature control circuits). According to their heating methods, they can be divided into two types: internal heating electric heating electric soldering electric soldering iron. Classes, which correspond to different use cases. 그 이유 왜 그것 is called an 내부 가열 유형 전기 납땜 철 is 왜냐하면 그의 납땜 철 헤드 의 내부 가열 유형 전기 납땜 철 is 중공, 및 그것 가열 코어 is in the inner hollow of the 납땜 철 머리, so it is called an internal heating type electric soldering iron.
그 외부 가열 유형 납땜 철 팁 그냥 그의 반대 의 내부 가열 유형 납땜 철. 그의 팁 의 외부 가열 유형 납땜 철 is 고체 및 일반적으로 만든 의 구리. 가열 코어 의 외부 가열 납땜 철 직접 랩 그의 납땜 철 팁, that is, the 납땜 철 팁 is 삽입 내부 가열 코어, SO IT is also called AN 외부 가열 납땜 철.
여부 그것 is an 내부 열 납땜 철 또는 an 외부 열 납땜 철, 그들의 작업 원리 is the same. The power plug of the electric soldering iron introduces household AC220V alternating current to both ends of the heating core, and the heating core is energized to generate heat.
A small part of the heat emitted by the heating core is lost to the surrounding air, and most of the heat is exported to the soldering iron tip. The temperature of the soldering iron tip can reach 200-450 degrees, which can melt the solder for welding.
왜 할까 납땜 철 아님 스틱 to 납땜
1. The Electric soldering iron has been used for a long time, the internal heating core is aging or damage, and the heat emitted cannot reach the melting point of the solder, resulting in the soldering iron tip not sticking to the solder.
2. During daily use, the soldering iron tip is not tinned after using the soldering iron, which causes the soldering iron tip to oxidize with the air at high temperature.
3. After using the soldering iron, it was not cut off in time. The soldering iron is in a high temperature state for a long time, and it will oxidize with the air, resulting in non-stick solder.
4. In order to pursue convenience in daily soldering, acidic flux is used, which oxidizes the tip of the soldering iron at high temperature.
5. The problem of the soldering iron tip itself. Some soldering iron tips with poor materials are used. For example, some soldering iron tips are directly made of iron. This type of soldering iron tip itself is extremely prone to oxidation.
