Clean oven model matching equipment selection key points：Match clean-oven models by particle targets, filter temperature limits and usable loading space rather than volume alone. Describe scale-up using usable tray area, part layers, spacing and thermal load per batch; nominal-volume ratios do not directly predict throughput.

Plasma cleaning machine capacity matching process verification and risk control：Size plasma chambers from holder layout, shadowing and usable treatment space and use coupons to validate positional differences. Retain the material endpoint and sample-temperature window from laboratory trials, and remeasure heating, evacuation, purge and cooling times in the larger chamber.

Large capacity oven configuration confirmation process verification and risk control：For large-capacity configurations, first check door aperture, trays, load heat capacity and complete cycle time. Compare lab and pilot results at the most challenging load positions, then assess accepted output per batch and complete cycle time.

Compare sample temperature, chamber recovery and gas-inlet temperature before and after admission at the same flow; validate preheating through sample thermal-shock behaviour and check line temperature limits. Define the oxygen sampling location, analyser delay and calibration method. Test with a real load and after door opening; supply-gas purity cannot substitute for chamber oxygen measurements.

Verification and risk control of drying process for easily oxidized powders：Trial powders at the actual bed depth and inspect dust disturbance, agglomeration and oxidation after treatment. Define the oxygen sampling location, analyser delay and calibration method. Test with a real load and after door opening; supply-gas purity cannot substitute for chamber oxygen measurements.

Metal terminal anti-oxidation heat treatment process verification and risk control：Distinguish terminal oxidation from cleaning residue and judge the effect through later soldering or contact performance. Confirm the sequence of evacuation, nitrogen admission and heating, and whether the circulation fan can operate in vacuum mode. Screen pressure-sensitive samples on a small load first.
