Summary (sPHENIX SAMPA V5 production): 
Number of chip tests done : 389
Number of chips tested    : 389
(some chips tested more than once)
 
The 389 tested chips are split among the following categories: 
Number of OK chips  : 0
Number of Bad2 type : 245 - issues with any of DFT, Jtag, Mem, i2c, Pedestal (stuck bits) 
Number of C1   type : 144  - issues with any of currents, sync + Rms, Xtalk, RiseTime, Gain 
Numver of C2   type : 0  - spare candidates, with lowish gain 
 
 Yield estimate (using only OK QR chips): 
 Tested OK : 0 / 389 = 0 %
 
 Optimistic Yield estimate (using OK + C1 + C2 QR chips, i.e. assuming we could also recover all C1 chips): 
 Tested OK or C2 or C1 : 144 / 389 = 37.018 %
