Immersion coating methods utilize a chemical process for depositing a flat metal layer directly on the copper traces. Besides providing a flat surface for parts to be soldered to, tin immersion does not require the use of lead; therefore, this process yields a RoHS-compliant PCB surface. Unfortunately, the use of tin allows for the possibility of tin whiskers.
