This involves using thermocouples to monitor oven temperature at different locations inside the chamber. Consistent calibration ensures that the temperature profiles match the needed specifications for the materials.
Creating a heating schedule: A well-defined heating schedule ensures that components reach the right temperature at the correct rate. Generally, a profile consists of the following segments:
– Preheat: Gradually raise the temperature to avoid thermal shock, usually to around 150°C for 60-120 seconds.
– Soak: Maintain a steady temperature (approximately 180°C for 30-60 seconds) to allow for even heating and to activate flux.
– Reflow: Increase temperature rapidly to reach peak (around 230-250°C) and hold for 30-90 seconds to ensure solder melts and flows properly.
– Cool down: Gradually lower the temperature to avoid component damage, usually at a rate of 4-6°C per second.
Testing and adjusting profile: Once the initial profile is set, it is beneficial to run test batches and adjust the profile as necessary based on observed results. Pay attention to solder joint quality and component integrity. Feedback from practice sessions helps refine the profiles for optimal performance.
Monitoring during the process: Continuous monitoring during the reflow process is critical. Use data logging to capture temperature at various points.
