What to pay attention to when soldering diodes

In order to save more costs, save space, improve integration, and achieve high efficiency, many people will choose related welding equipment to weld diodes, but due to lack of experience, many people find it difficult to weld diodes. In fact, welding diodes is not difficult. Just need to pay attention to a few points when soldering the diode:

1. During the welding process, it should be noted that the welding time should not be too long, and some diodes cannot be welded with electricity to prevent breakdown;

2. Diode, a device with two electrodes among electronic components, only allows current to flow in a single direction, and many uses are for its rectification function. The varactor diode is used as an electronic adjustable capacitor. The current directionality of most diodes is commonly referred to as the "rectification" function. The most common function of a diode is to only allow current to pass in a single direction (called forward bias), and block it when it is reversed (called reverse bias). Therefore, the diode can be thought of as an electronic version of the check valve;

3. If it is a SMD diode, pay attention to the welding temperature. Generally, a constant temperature electric soldering iron is used, and the temperature is controlled at 350 degrees to prevent the diode from being burned due to excessive temperature. When welding, the power supply of the welding component must be disconnected.
