Capacitor Metallization Evaporator Boat,
Food Package Metalization Evaporator Boat,
Boron Nitride Ceramic Evaporator Boats
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.
D.Adjust wire feed to the very central position on boat surface.
E.Follow heat-up cycle to ensure reannealing of boats during first heat up (approx. 12-14 minutes).
F.Start wire at 75% of normal feed rate and reduce power to achieve maximum wetting over length of cavity.
G.Start metallizing and increase wire feed rate over the first 15 minutes of production.
H.Upon completion of the coating:
Stop the wire
Stop power 20-30 seconds later
I.Wait approx. 2 minutes to release vacuum to ensure boats have cooled to below red heat.
J.Clean boats with a wire brush after every cycle.
Evaporator Boat – Characteristics and Applications
A.2-Component evaporator boat is the most common product for most evaporation applications
B.Particularly suitable for food package metallization process
C.Good performance in AlOx metallization process
D.High evaporation compared to 3-component family
