1. Status of Medipix Quads in Institute of Physics Prague
Lukas Tomasek Institute of Physics ASCR Prague
Medipix meeting, 31 Jan 2008

2. We just received first batch of 4 Medipix Quad assemblies from IZM:
another 4 quads will follow soon...

3. Readout Chips – Medipix 2 MXR
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

4. SnAg bumps and flip-chip by IZM (Berlin, Germany)

5. 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.
