Osp Pcb Surface Finish

Osp Pcb Surface Finish

OSP is short for Organic Solderability Preservatives. OSP is a water-based, organic surface finish that is typically used for copper pads. It selectively bonds to copper and protects the copper pad before soldering. OSP is environmentally friendly, provides a coplanar surface, is lead-free, and requires low equipment maintenance. However, it’s not as robust as HASL and can be sensitive while handling.

Advantages:

The latest OSP formulas are far more robust and are designed for lead-free assembly. They can handle multiple heat cycles and have a one year shelf life. That's the reason why more and more PCB manufacturers choose OSP Finish.OSP pcb surface finish has lots of advantages. Briefly introduce a few today.

1. Simple process, the surface is very smooth, suitable for lead-free soldering and SMT.

2. Easy to rework, easy to operate, suitable for horizontal production line.

3. One panel can have different surface finish (such as OSP + ENIG)

4. Low cost, environmental friendly.
