Immersion Tin Process

Immersion Tin - Ormecon CSN7001 is a nano-metal, the Immersion Tin process uses and ion displacement reaction to plate the circuit board surface. When the surface metal finish (tin) has been deposited, the source of electrons is used up and the process is complete. The process is self-limiting because the copper forms an inter-metallic layer that inhibits the immersion reaction. Immersion coatings have become popular as circuit densities have increased and the pitch of surface mount technology components has decreased. This Immersion tin process provides fast efficient tinning of copper PCB's, a single dip at room temperature produces bright tinning in seconds.

Traditional Hot Air Solder leveling is simply not able to cope with he fine pitch tracks and small air gaps on modern boards. A flat attachment pad is paramount in achieving a reliable solder joint with fine pitch parts.

If this tin process is used after copper polish it results in a board with an ultra bright mirror finish (a 30cm+ shine). This leaves a highly solderable anti-oxidizing finish.
