1
We just received first batch of 4 Medipix Quad assemblies from IZM:
another 4 quads will follow soon...
2
Our Quads:
• Readout Chips – Medipix 2 MXR
• Sensors – 300 micron thick Si (P on N) manufactured by
ON Semiconductor (Roznov, Czech Rep.)
standard squared and
also hexagonal pixels
3
• SnAg bumps and flip-chip by IZM (Berlin, Germany)
4
No testing with assemblies done yet (except x-ray scan at IZM)=>
To do next:
-
attachment+wirebonding to a standard quad pcb (Nikhef?),
verification the basic functionality is ok (sensor, readout, bumps),
some more detailed comparison between the pixel variations;
-> input for the next iteration of sensor design and parameters.
