The bound type of metal pressure springs in touchpad (for experts)
Dear experts, on mbp touchpads with taptic engine, the glass layer and sensor layer are attached each other with adhesives. And as you can see in the image below, these 2 adhered layers float on 4 metal springs which behave as pressure sensor and activate the taptic engine according to pressure level.
At this point how the top layer (glass+sensor) is connected or attached with these 4 springs? Does manufacturer use the same strong adhesives for contact points of these springs and the layer over them?
Can a strong horizontal force or shear force damage the bound and dislocate/slide the top layer over metal springs?
Is this a good question?
