Evaporating tungsten boat is referred to as the tungsten boat that is widely applied in the vacuum evaporation coating industry. This type of tungsten boat is used at high vacuum environment so that its demand of work environment is relatively strict.
The evaporating tungsten boat is different from other types of tungsten boat in: This type of tungsten boat is generally composed of a tungsten boat cover and a tungsten boat body. Generally, there are evaporating round hole on the tungsten boat cover with diameter of 1mm and hole pitch of 2mm. These holes can effectively prevent the raw material from splashing out of the tungsten boat so that it can not only ensure the quality of the finished product, but also save the raw material. What’s more, it also facilitates the sublimation and evaporation of the material to improve the coating efficiency.
Producing process of evaporating tungsten boat is similar to the process of stamping tungsten boat where the difference is the former has the holes on the cover.
