Video: How to Connect Electrical Legs to Substrates for Measurement
This video demonstrates how to connect electrical legs to substrates 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 such that they engage. 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 misalignment can cause measurement errors as more than one pixel will be active at once resulting in an artificial doubling of performance.
Extra care should be taken when engaging the substrates in the legs and only gentle 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.
