To achieve this, IPC-7801 details a methodology for performing temperature measurements over time to establish a baseline profile. Once the baseline is set, the standard provides requirements for periodic verification to ensure the oven continues to perform within acceptable limits. It is intended to be used for any conveyerized thermal process for soldering surface mount components using reflow ovens, covering the entire process from pre-heating to final cooling.

Process Capability Index () acts as the core mathematical validator within the standard. By tracking localized peak temperatures and dwell times across repetitive test runs, operators can calculate a Cpk value for the machine. A high Cpk ensures that the reflow oven possesses enough stability to consistently cook components safely within their process windows without running hot enough to delaminate laminate structures.
