Difference Between A Hot Air Rework Station And An IR Infrared BGA Rework Station

The main difference between a hot air rework station and an IR BGA Rework Station is the way they heat the board. A hot air rework station uses heated air to transfer heat from the tool-to-board interface and into the solder balls, whereas an IR BGA Rework Station uses infrared light to heat up just enough of each ball so that it melts.

The next important difference is how they control temperature: Hot Air rework stations use PID temperature control, but IR BGA Rework Stations use proportional pressure modulation (PPM). PPM is more precise than PID because it can monitor changes in pressure within milliseconds. This means that when applying flux to a board or when reflowing solder balls on a board, you can rapidly respond by adjusting your PPM settings as necessary. With PID, this would take about 20 seconds per change due to slow response times in most systems.

Another key difference lies in airflow control systems; hot air has no need for specialized airflow since there's no need for cooling during reflow since all of that happens outside of the oven chamber using an external fan which blows across all areas equally regardless if they are close or far away from each other.
