Pads for probe cards in ALICE-D2 /05.03.2000/
(X,Y) coordinates are quoted in microns and referred to the centers of bonding pads.
(0, 0) corrispond to the center of the detector.
Convention:
left is for negative X, right is for positive X;
DOWN half is for negative Y, UP half is for positive Y.
Detector size: X= 87588 μm; Y= 72500 μm.
Detector corners:
LEFT UP: (-43794, 36250)
RIGHT UP: (43794, 36250)
LEFT DOWN: (-43794, -36250)
RIGHT DOWN: (43794, -36250)

Anodes (n-side)
There are 256 anodes to be bonded to the inputs of front-end electronics. In addition there are 2 anodes (one at the left edge and one at the right edge of the anode array) that have to be bonded to the ground. I call these 2 anodes #L and #R. The pitch of all anodes is 294 μm.
