Generally speaking, the brightness of solder joints is only an appearance factor. During solder paste surface mount processing and soldering, whether the solder joints are bright or not is also a relatively important parameter. The brightness of the solder joints affects the appearance quality of the product. Nowadays, many product users have certain requirements for the appearance of the product. Therefore, when we are soldering solder paste patches, we should pay attention to the brightness of the solder joints. However, during the solder paste surface mount processing and soldering, it cannot be guaranteed that the brightness of every solder joint meets the requirements. So, what factors are there......
