Reflow Oven Redundant Process Monitor

Profile Guardian pairs a thermocouple probe at product height with software to monitor temperature deviation from baseline – independent from control TCs. The redundant process monitor is aware of reflow oven state (recipe change, energy savings modes, etc.), and monitor data can be included in host communications (MES) from the oven. Additionally, it provides board level traceability when paired with bar code readers, which is a requirement for many large OEM/EMS customers as well as for Industry 4.0 implementation.

Profile Guardian is fully integrated with the Wincon™ reflow oven control system, each recipe has a baseline. A baseline is a collection of data that captures the median data point (the baseline), the spread and how much variation there is during normal operation. Charts provide the user with simple data visualization, showing the baseline, actuals, recipe set points, current status, and track deviations.
