jwt0625 shares a paper figure (Fig. 13, "Substrate delamination post thermal exposure") joking that it looks like a nice 3D surface heatmap — but it's actually the measured delamination height profile or temperature distribution.
The macro shots show a chip substrate with red blister-like delamination after thermal exposure, alongside a PCB pad array. The figure is being shared for the amusing contrast of looking like data visualization while being a physical measurement.
