It must feature a high thermal endurance layer (such as thick FR4 or polyimide) that will not warp or degrade under hundreds of thermal cycles.
By controlling the oven environment, you reduce defects related to insufficient heat (cold solder joints) or excessive heat (component damage).

Many "free PDF" sites are honeypots for ransomware. Your SMT line PC getting infected can cost thousands in downtime.
If you search for "ipc7801 pdf free download" on file-sharing websites, you are likely to encounter outdated, watermarked, or illegally scanned copies. Using a bootleg copy exposes your company to legal liability and audit failures (e.g., ISO, AS9100).

Recognizing that a well-maintained oven is key to a repeatable process, the standard also includes guidelines on maintenance and calibration. This addresses operational aspects such as nitrogen usage, general housekeeping and daily maintenance, preventive maintenance schedules, and formal calibration procedures.
Batch ovens or oven-specific product recipes (the specific temperature setpoints for a specific board).
