Osp Pcb Surface Finish
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.

From smartphones to kitchen appliances, electronics play a large part in our daily routine. At the heart of each of electronics is a printed circuit board (PCB).
OSP PCB Surface finish’s application is following:
Check for line width and spacing
Check for solder paste
Check for components down to 0201"
Check for missing components, off set, incorrect parts, polarity
Check for the BGAS
Check for the Micro BGAS
Check for the chip scale packages
Check for the Bare board
Flash device programming
