"Are you still bothered by wire breakage, cold solder joints, and wrong soldering during wire soldering operations? Don't worry! Wire soldering may seem simple, but the actual operation is full of 'pitfalls'. For example, stripping just one millimeter more of the wire can lead to a short circuit, using the wrong heat-shrink tubing can result in immediate rework, and even forgetting to install a 2KΩ color-coded resistor can directly ruin the entire circuit!
