When soldering high voltage connections, what is important to achieve on the terminal?

Achieving a smooth and rounded covering of solder on high voltage connections is essential for several reasons. First, this type of solder joint promotes good electrical conductivity, which is vital in high voltage applications where resistance can lead to overheating or failure of the connection. A smooth and even solder joint ensures that the current flows efficiently and reliably without creating hot spots or potential failure points.

Additionally, a well-formed solder joint helps to create a strong mechanical bond between the components, which is important in high voltage scenarios where vibrations or physical stress might occur. This strength can prevent disconnection or damage to the terminal over time, especially in environments where the equipment is subject to movement or thermal expansion.

Furthermore, smooth solder joints are generally more effective at withstanding environmental factors such as moisture and oxidation since they have fewer crevices or irregularities where contaminants can accumulate.

In contrast, rough or uneven solder joints may compromise the integrity of the connection, leading to potential failures or safety hazards, particularly in high voltage applications. Thus, focusing on creating a smooth and rounded solder covering is crucial for ensuring both the performance and longevity of the electrical connections.
