Applications/Examples of results
What is copper dissolution? When a drop of ink is added to a glass of water, the water gradually becomes colored. Similarly, the phenomenon where copper (Cu) dissolves into tin (Sn), which is used as solder material, is generally referred to as copper dissolution. This phenomenon tends to progress more easily at higher dissolution temperatures and longer dissolution times, so it is important to solder at lower temperatures and for as short a time as possible.
