  • Technical Tip

Maximizing Boat Lifetime

Over time, boats will need to be replaced as they go through cycles of extreme heat and cooling down. However, some materials, when molten, can alloy or corrode through metals.

 

Improper boat selection can lead to source failure, causing unnecessary inefficiencies in your thin film coating process.

 

Here are some considerations to take into account when selecting your evaporation boat sources:

1. Take into account material thickness. Thicker material will be able to withstand more corrosion when compared to thinner boats.

S47

Pictured is the S47 boat, available in thicknesses up to .020”

 

 

2.   Consider adding tungsten wire mixture to the boat. Tungsten mix allows material to wet to it, preventing migration or splattering. This mix also acts as sacrificial clippings against corrosion.

3. Utilize aluminum oxide when applicable. Alumina coatings are chemically inert to most materials, protecting refractory boats from reacting with evaporation materials.

S3-AO

Alumina can be applied to a wide variety of boat sources, like the S3.
