|Board Status ||0 ||tested fine initially and was in pit; was found to have problem with L1ID on top half of board
to be checked more thoroughly in 104 - misc to V4 soldering problem?
Turned out to be bad link between V2 and V4 top on slink connection pin
13 June: Board brought to CERN shop for reheating of V2
Connection between V2 and V4 slink problem solved
29 June: problem returned. Exact same line (74) is open again after being in pit for two weeks.
5 July: board brought to CERN shop for reheating (take 2) of V2 chip to see if it can fix the problem
9 July: board might be okay; connection looks fixed but am I losing one or two events from 10000 with the slink?
19 July: problem on channel returned
13 Aug: verified (bcl + WO) that line 74 of V2-V4t is still open (V2 pin A25). Pushing on V2 will bring the line back temporarily. Recommend board for V2 replacement at CERN shop.
Board is operational in USA15 so is considered to have passed all tests, this might need to be verified at some point (alex 8/5/08). Still some concerns that this board is really fully operational, see history above.
dec 16, 2014: sent to UBC for repair.
Feb, 2015: Components replaced (CC11,C102_Vb,C25_Nb, C13_Nb,C161,C8R,C9R,C16_Vt,C418,C272,R1). ||29-04-2015|
