Multiple Lead-free Profile

What is a multiple lead-free profile? Why is it necessary?



S.Y.

Experts Comments

It appears that you are describing a multiple ZONE lead free profile.

Multiple zones are required for production soldering to ensure that the assembly being soldered is heated in a safe and controlled manner. This ensures that the board and components are heated from room temperature to reflow temperature and back to room temperature without damaging overheating or underheating that would cause cold solder joints.

You can consult with your solder paste supplier for information on the proper parameters for your solder.
