What does a perfect surface mount solder joint look like?
Perfect surface-mount solder joints have several key attributes that ensure functionality and reliability of electronic assemblies.
First, a good solder joint surface must form a stable intermetallic compound (IMC) layer. The IMC is critical to establishing a strong electrical connection and ensuring the longevity of the solder joint under a variety of operating conditions.
Second, it's easy to check the joints by appearance. An ideal solder joint is always shining. Discoloration or dullness may indicate poor soldering technique or the presence of contamination, which can compromise the integrity of the solder joint.
Third, the right amount of solder is critical; it should completely cover the pad and the soldered portion of the pins. Missing solder will result in a weak connection, while too much solder may form bridging.
Fourth, mechanical strength is another key characteristic of a perfect solder joint. The solder joint must have enough mechanical strength to prevent the component from loosening or falling out during operation.
In short, a perfect solder joint is shiny appearance, good electrical connection performance, and mechanical strength. The amount of solder paste is moderate, and the height of the components is moderate. For good wettability, the edge of the solder joint should be thin, and the wetting angle between the solder and the pad surface should be less than 300.
