Video: How to Connect Electrical Legs to Our Scale Up Substrates

 

 

This video demonstrates how to connect electrical legs to our scale up substrate system for measurement using zero insertion force (ZIF) sockets.

Attaching legs to devices enables easy and repeatable measurements. The legs can be attached by placing them on a flat surface (clip side up) and then placing the substrate vertically on the clips before gently pressing down on one corner such that they engage. Using a glass test tube, the rest of the legs can be engaged down the length of the substrate. This step can then be repeated for the other side of the substrate. Visually inspect the legs to check their alignment with the ITO as mis-alignment can cause measurement errors as more than one pixel will be active at once resulting in an artificial doubling of performance. This process can be made easier by first scraping the substrate edges with sandpaper.

Extra care should be taken when engaging the substrates in the legs and when connecting the remainder of the legs. Only gentle but firm pressure should be applied as there is the potential to break the substrate.

After the legs have been attached, the bottom and top of the legs must then be removed. This can be done with a sturdy pair of scissors while the top can be removed by holding the substrate in one hand with the thumb and fore-finger and gently bending the top until it snaps off. Recheck the alignment of the legs with the ITO as they can be moved slightly during the cutting process.
