      Hello all. i m testing a CY8CMBR2016-24LQXI bsed keypad board. I m a bit confused about the touch sensitivity. The touch pads on pcb has Green masking.  And when i touch over it, it is sensed and corresponding output is made. I m confuse about "OVERLAY " as mentioned in related documents. Is the green mask over the touch pads is here considered as overlay ? Or i can use any other material as OVERLAY ? I have tried placing a adhesive sticker over the touch pads with almost zero gap for air, but it doesnt work. But without the sticker, touch pads works fine. BTW i will  be using a individual membrane/cover to cover the keypad,once i am clear about the overlay part.
