By thin, I mean about 0.1". No special environmental requirements. Also, we only need to detect the wafer presence, and don't have to gauge their precise positions. All other requirements (type of signal generated, etc) are flexible. We can always use adapter circuitry to modify the...

We're using containers which are manufactured by our customer, so I don't have any choice in the matter. We've come up with a series of workable solutions since I posted that inquiry, thankfully.

Actually, we're NOT using a vacuum paddle, and we can't use a laser sensor either, due to intellectual property considerations). That's why I'm looking for a thin capacitive sensor. We've been forced to abandon all those other solutions.

We tried an optical sensor, and it worked quite well. Unfortunately, we can't use it due to intellectual property concerns. (For pity's sake!)

If you mean a vacuum sensor, then no, it's out of the question. We're not using vacuum to grip the wafers. Rather, we're using a mechanical fixture.

Hello, all. I'm looking for a very thin sensor that I can use for detecting silicon wafers. It is to be used in a robotic end-effector for the semiconductor industry. I had previously planned on using a thin capacitive sensor which was to be offered by a certain vendor. Since then, I've been...

Sorry for the late response. Apparently, I never received the e-mail notification that someone had replied to this thread. Anyway, I was able to design my own repeatability setup, using LabView and some inductive proximity sensors from Kaman Instrumentation. I have yet to build this setup...

Greetings, all. I need to find and evaluate a positioning repeatability setup for some robots. Unfortunately, I'm not sure where to start. Can anyone recommend a vendor or website that I can look at? If at all possible, I'd like to have up to four repeatability setups connected to the same...

I have an application wherein a robot needs to pick a silicon wafer off of a stack. The stack consists of wafers interleaved with sheets of separator paper. Unfortunately, the silicon wafers have a way of sticking to the interleaf sheets, and to each other. This appears to be due to static...

It sounds to me like you're working on a school paper of some sort. If so, then I think it would be best for you to do a bit more reading first, so that you can ask some specific questions. Power ratings, for example, will vary tremendously based on the application. (Also, this seems like a...
