How to Set Reflow Oven Temperature Profile

Setting the correct reflow oven temperature profile is essential for achieving reliable solder joints. The profile must be customized for each PCB assembly based on board thickness, component density, and solder paste type.

Steps to set your profile:

1. Consult solder paste manufacturer datasheet for recommended profile
2. Attach thermocouples to representative PCB locations
3. Run the board through the oven at a starting speed of 80 cm/min
4. Analyze the thermal curve and adjust zone temperatures
5. Fine-tune conveyor speed to meet all profile requirements
6. Document the final profile for production reference
