Key points for selecting ceramic substrate heat treatment equipment
Before choosing operating conditions for ceramic-substrate heat treatment, define the observable material result and the actual load.
For ceramic substrates, check support, warpage and thermal shock and assess a furnace if the process exceeds the oven range.
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.
