The original design can be utilized with either side clamping (armchair) or end clamping.        
Maximize surface evaporation while improving the temperature uniformity.  
Lower power consumption and increase yield of aluminum to the substrate.  
Improved initial wetting for faster startups.      
Ease of use providing operators a visual indication for initial temperature adjustment.        
Significantly extends boat life, boosting metallizing productivity.        
Prevents metal overflow and dramatically reduces spitting.        

Evaporator Boat – Characteristics and Applications


  • 2-Component evaporator boat is the most common product for most evaporation applications
  • Particularly suitable for food package metallization process
  • Good performance in AlOx metallization process
  • High evaporation compared to 3-component family  

2-Component Premier

  • Improved corrosion resistant at high temperature
  • Higher evaporation rate as it works with high temperature
  • Developed for customers that need high coating thickness and high evaporation rate

3-Compontent Family


  • An economic option for an evaporator boat
  • Can be used for both food package and capacitor metallization
  • Lower evaporation coefficient than 2-Component boat


  • Higher AlN content than G-Component, therefore higher mechanical strength than G-comp and less creeping (bending of the boat)
  • Mainly used in capacitor metallizing application, where evaporation rate is lower than food package metallization and the usage time (wet time) is much longer (up to a week or more) than in food package metallization (up to 15 hours)


  • Highest purity in all composition
  • Perfect balance point in thermal shock/high temp mechanical, which could meet special application.
  • Not used for evaporator boat application
  • Use for crucible for OLED/semi-conductor, where purity and high temperature properties are critical for the application


  • Highest application temperature
  • For various metals, including aluminum (Al), copper (Cu), zinc (Zn), chrome (Cr), nickel (Ni), tin* (Sn), and silver* (Ag).
