ABSTRACT:
Evaporation boats utilized in the vacuum metalizing process are categorized based on evaporation characteristics thereof to match similar boats for the metalizing process. Power is supplied to the evaluation boat and the period of time required for the evaluation boat to reach a predetermined temperature is monitored. This period of time is indicative of the evaporation rate of the boat during the metalizing process and is used to categorize and match boats as super slow, slow or fast.
