FAQ:
Quesion: What is Organic Solderability Preservative (OSP) or Anti-Tarnish Surface Finish?
Answer: The overall functionality of a PCB board depends upon the conductivity of copper tracks. These tracks tend to oxidize when exposed to the atmosphere, which creates a problem when soldering components on the board. Organic Solderability Preservative (OSP) regulates two things; temporary protection of exposed copper from being oxidized and improving the solderability before component fixation (assembly).
OSP is a very thin (100-4000 Angstroms) organic coating on the PCB board, which is a water-based chemical compound of the ‘Azole family’ such as benzotriazoles, imidazoles, and benzimidazoles. This compound gets absorbed by the exposed copper and generates a protected film.
Advantages of Organic Solderability Preservative:
Disadvantages of Organic Solderability Preservative:
OSP Surface Finishing Process:
The OSP finishing process is composed of three major steps that include pre-cleaning and making the PCB board ready to apply a smooth OSP coating:
