When the original SCK-100 model was released some years ago, the options if you wanted a Spin Coater was either go through the trouble of building your own with almost no online help, or spend about 3 – 5 thousand dollars for a commercial unit. Now, there are more options. If you want a DIY Spin Coater, there are a quite a few sites and Journal articles for doing so. Moreover, the price point for some low-end Commercial Spin Coaters now start at about $1,200. We can’t comment on the quality, or level of technical support for this models, but for that price, we wouldn’t expect much. However, the questions still remains, when do you build your own, buy a commercial unit, or the option we like the most, buy one of our SCK-300 kits. To help with this decision, here are some simple rules of thumb.
- If you need a Spin Coater for precise/production work, or for coating relatively large substrates (greater than 300 mm), then definitely get a good commercial unit from a company with a document track record ( Chemat Scientific, MTI Corporation and Laurell). These units will allow for better control of the coating process, and are more flexible.
- If you need a Spin Coater to establish proof of concept, or for none precision work etc…, then consider buying one of our SCK-300 kits. In general, you should only consider building one from scratch if you already have the in-house electronics/machining expertise.
