Joe Silber - Attached are measurements I made yesterday.
1) If I divide the total width of 10 butted sensors by 10x Leo'snominal width (19.62mm) I get an average gap of 2um.2) If I instead divide by the width I measured (19.607mm) then I getaverage gap of 16um.3) If I add up the worst cases of offset and rotation that I measured,then the maximum tol envelope would be 54um.4) If I add up the stdevs on offset and rotation that I measured, thenthe tol envelope should be 18um.
Clearly I may be simply interpreting the edge of sensor incorrectlydue to my lighting conditions. If so, then the average gap is is tiny,2um, as in case (1). But if I am seeing things correctly on thesmartscope, then this batch of sensors were cut undersized by about13um on average, and the correct gap to model would be more like16-18um, as in cases (2) and (4). Case (3) is essentially what Howardoriginally assumed (2 mil), but in reality it looks to me like itwould be incorrect for us to assume this worst-case placement on everysensor.
I think the bottom line is that if Leo can stomach about 100um maximumerror for wire bond alignment, then we should be fine splitting thedifference between the 2 um and 18 um numbers, and calling the nominalgap 10um.
