Frequently asked questions
How susceptible to corrosion is immersion tin in the field if some solder pads are not covered with solder?
Immersion tin is generally more susceptible to corrosion than other types of tin, such as the type used for lead-free HAL. If not all solder pads are covered with solder, it can lead to corrosion in the exposed areas, as the underlying copper or other metals can become oxidized by moisture or other environmental influences.
Susceptibility to corrosion can also be influenced by other factors such as the thickness of the tin layer and the composition of the solder. Therefore, it is important to check meticulously that all solder pads are fully covered with solder. If necessary, touch-ups must be performed to ensure the long-term integrity of the soldered connections.
