Thin Film Coating

When it comes to depositing highly-uniform wet thin films, there are many different solution-processing techniques capable of producing high-quality films at low cost.

Spin coating is a common technique for applying thin films to substrates. When a solution of a material and a solvent is spun at high speeds, the centripetal force and the surface tension of the liquid together create an even covering.

Dip coating is a simple and effective technique which is commonly used in manufacturing across a wide range of different industries. Within research and development, it has become an important coating method for the fabrication of thin films using a purpose-built dip coater.

Slot-die coating is an extremely versatile deposition technique in which a solution is delivered onto a substrate via a narrow slot positioned close to the surface.

Spray deposition or spray coating is a scalable wet-coating technique used in many applications. Spray coaters are used in many industries to coat large substrates or objects with odd shapes. The flexibility of the applicator and robustness of the process means that spray coating can be adapted to coat almost anything.

A spray coater is a piece of equipment that facilitates the coating of a solution onto a surface using spray coating methods. Spray coating involves breaking up a coating solution into tiny droplets and directing this spray towards a coating surface using pressurized gas. As the droplets hit the surface, they coalesce to form a continuous film.

This video demonstrates the static dispense spin coating method using 45 degree angle to avoid touching the edge of the substrate whilst moving the ink.

With no external dependencies, the Ossila Syringe Pump is quick and easy to set up and use.

When auto dispensing solvents, droplets are sometimes dispensed after the syringe pump has stopped. The cause of solution dripping can be due to several factors.

The Spin Coater Advanced offers more control than the classic spin coater in a wide range of areas. These advancements make the our advanced spin coater ideal for high-precision and demanding applications.
