SILAR Coating System with Stirrer

Model: HO-TH-03A8

One of the newest solution method for the deposition of thin film is Successive Ionic Layer Adsorption and Reaction (SILAR) method, which is also known as modified version of chemical bath deposition. As it is a chemical method, a large number of varieties of substrates can be coated.

Holmarc’s SILAR Coating System has been designed to automate the entire process to avoid operator fatigue and errors associated with it. In manual SILAR process, the operator has to perform hundreds of repetitive dipping into the solution and water. It is very difficult to control dip duration and number of dips in a manual process which can last hours. In the automated unit, the operator need just to clamp the substrate into the holder and program the controller with required dip cycles and duration.

This model: HO-TH-03A8 has a motorized substrate holder which can be used to stir the solution. In this model eight beakers placed in a circular arrangement about the rotation axis of sample dipping arm. There will be heating plate for each of the beakers. Maximum diameter of hot plate surface on each of these 8 positions will be three inches. By rotating the substrate along with the holder at desired speed, the solution can be kept stirred during the dipping process. The rotation speed is programmable from 2 - 200 rpm. The dipping speed, dip duration, retrieval speed and dry duration can be set for each beaker. Each hot plate can be set at different temperatures. The temperature can be set up to 350°C from ambient.
