Before choosing operating conditions for anti-oxidation heat treatment of metal terminals, define the observable material result and the actual load.
Distinguish terminal oxidation from cleaning residue and judge the effect through later soldering or contact performance.
Equipment decisions
-
Accept oxygen level, time to reach it and hold-stage stability separately; record nitrogen purity, supply pressure and consumption.
-
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.
-
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.
-
Check oxidation and moisture regain during cooling and unloading, together with exhaust routing, gas-supply failure response and site ventilation.
Trial and acceptance
Record the initial sample condition, loading layout, recipe version and raw measurements. Agree the acceptance endpoint before the trial; repeat at challenging load positions and compare the finished material result.
