The thickness of the glue \(t_{glue}\) is calculated as:
$$t_{glue} = \frac{1}{N_{c}}\sum_{c=1}^{N_{c}} z_{c} - \frac{1}{N_{b}}\sum_{b=1}^{N_{b}} z_{b} - t_{chip} $$
where \(t_{chip}\) is the thickness of the chip
\(z_{i}\) is the z-height measurement,
\(N_{i}\) is the number of measurements on a given surface,
and \(c\) and \(b\) run over measurements taken on the chip and base, respectively.
The assumed thickness of the chip is \(t_{chip} = 300\mu m\).
Uncertainties on the glue height measurement are estimated from the spread in z-height measurements on a given surface.
On a given surface, the height uncertainty \(\sigma_{i}\) is calculated as:
$$\sigma_{i} = \frac{\Delta z}{2\sqrt{N_{i}}}$$
where \(\Delta z = z_{max} - z_{min}\) and \(z_{max}\) and \(z_{min}\) are the maximum and minimum z-height measurements, respectively.
In addition, a conservative \(\sigma_{chip} = 10\mu m\) uncertainty on the chip thickeness is assumed.
The total uncertainty is calculated as:
$$\sigma_{glue} = \sqrt{ \sigma_{c}^2 + \sigma_{b}^2 + \sigma_{chip} }$$
The glue thickness measurements for each ASIC are shown in the figure and table below.
The thickness total stack up is measured from the top of the each chip to the jig,
and accounts for the combined thickness of hybrid flex, glue, and ABC/HCC chips in the case of hybrid.
The positions of the ASICs are measured on the 95x95 \(\mu m^2\) square pads on the opposite side of the sensor wire bonds.
These measured positions are compared against the technical drawns to calculated the relative ASIC position.
In some cases, the SmartScope incorrectly measures a different object than these square pads,
and using properties (such as the perimeter), the position is corrected.
The positions are shown in the figure below. If any corrections are applied, they are shown as transparent points.
The hybrid thickness is plotted below. It is calculated from the total stack up height minus the assembed chip thickness and measured glue thickness.
The tilt of a chip can be calculated in either the direction along the surface of a chip. We define
the x-direction to be any points whose difference is much larger along x, and similarly for y. The tilt in both cases is defined to be:
$$tilt = \frac{|\Delta z|}{\sqrt{\Delta x^{2} + \Delta y^{2}}} $$
