How to Choose and Maintain a Reliable Automatic Soldering Machine?
Source:
Since automatic soldering machines have been introduced into electronics manufacturing workshops, more people are asking about how to select a reliable one and how to properly maintain it. In this article, we'll provide some essential tips from Dongguan Key Electronics Factory, a trusted supplier of automated soldering solutions. There are many types and specifications of automatic soldering machines available on the market. Dongguan Key Electronics can even customize machines based on your specific needs. When choosing a machine, it's crucial to consider the size of the components you're working with. For small parts or integrated circuits, a 45W–75W external heating iron or a 50W internal heating iron is suitable. However, for larger components, a soldering machine with over 100W power is necessary. The soldering iron must reach the required temperature quickly to ensure a strong, stable connection. If the tip isn’t hot enough, it can lead to cold solder joints, which are weak and unreliable. When soldering, make sure the joint is not overly saturated. Ideally, the solder should form a smooth, concave shape between three to four points. Avoid creating large, bulbous solder joints, as they can cause short circuits or breakage. Keep the solder amount moderate, forming a semicircular shape that adheres well to the component leg. This not only improves aesthetics but also ensures better electrical performance. The soldering iron’s lead wire should not be too thin or too long, as excessive voltage drop (more than 5% of the initial voltage) can affect performance. Always wear protective gloves and safety glasses during operation. If any major quality issues arise within the first 15 days of purchase, you can contact Dongguan Key Electronics for a replacement. Never place the soldering iron directly on the sponge while in use—instead, keep the solder in a separate tin box to maintain the tip’s temperature. At the end of each day, clean the soldering machine, add sufficient solder, and then turn off the power immediately. This practice helps extend the machine’s lifespan and ensures it remains in good working condition. With proper operation and regular maintenance, an automatic soldering machine can last for many years. Most manufacturers, including Dongguan Key Electronics, offer on-site repair services for added convenience.
