Evaporation Boats for Vacuum Al Metalization Ceramic Evaporation
Boron Nitride Ceramics are widely applied in automobile, electronic, electrical engineering, aerospace, medical science, scientific research, for extreme difficult environments such as
electrical insulation, thermal insulation, high temperature resistance, chemical resistance, etc.
Optimizing Each Evaporator Boat Application:
A.Resistance-heated boats or crucibles are used in vacuum chambers
at ~1500–1650℃ (2732–3002℉) to evaporate various metals, including
aluminum (Al), copper (Cu), tin* (Sn), and silver* (Ag).
B.Metallized films and papers are used in the food packaging,
capacitor film, decorative, and electronic industries.
Maximizing Evaporator Boat Life
To ensure optimum boat performance and to maximize boat life, the
following procedures should be followed:
A.Check alignment and smooth surface of your contacts.
B.Use graphite tape for uniform electrical and thermal contact.
C.Use pieces of aluminium wire for first heat up to determine
correct initial boat temperature.
Evaporator Boat – Characteristics and Applications
A.2-Component evaporator boat is the most common product for most
B.Particularly suitable for food package metallization process
C.Good performance in AlOx metallization process
D.High evaporation compared to 3-component family
A.Highest purity in all composition
B.Perfect balance point in thermal shock/high temp mechanical,
which could meet special application.
C.Not used for evaporator boat application
D.Use for crucible for OLED/semi-conductor, where purity and high
temperature properties are critical for the application
