Select a Table

The machine will be permanently attached to its base. You might want to dedicate a table for it or do what I did, get just the tabletop and mount it on some kind of feet  (I have 2×4’s under the tabletop plate). You want to consider at least these issues:


You want the table to be ESD safe, or at the very least, have ESD protection mat on the work surface. The LitePlacer is aimed for prototype build and therefore, you might use a less stringent ESD rules than in real production. Still, ESD is an issue with modern parts. A moving machine will generate static charges, and even though the machine itself have conductive paths, the charges still have to have somewhere to go.


The table needs to be sturdier than you think. (I had to add support in the middle of the development project.) You are mounting a machine with moving parts on it. You don’t want the table to move or shake, and when the gantry moves around the work area, you don’t want the base of the machine flexing. Even a fraction of a mm flex will show up in final results.

Surface Smoothness

Any texture on the table will be seen by the camera. Texture on the table will work pretty much like the disturbing lines on captha tasks: A human can see the shapes, but for a machine, the task will be very hard.

My sturdy, ESD safe Treston tabletop that I purchased, has a slight texture on it. It is very slight, but the camera does indeed see it. Therefore, I had to put smooth ESD mats on it. (I’m not bashing Treston at all; they make very good ESD furniture, just not one that is optimized for optical recognition tasks. 🙂 )


The machine itself will take about 60cm x 90cm. If you plan to use a computer, have the electronics or need general work surface on the same table, reserve room for these accordingly.


Finally, check the material. A metal table might be problematic, as you need to make a hole to your table.
