when something like this happens I usually do a connector and PCB slot cleaning. apply contact cleaner and plug/unplug (slot/unslot) connector (PCB) few times then blow it out dry. do it for each PCB and connector.

is Mark3 program started on startup or do you start it manually? It can be like this if you run it manually. Other cause is bad contact in PCB slot or connector in 90% cases. Wash then with contact cleaner and insert and pull out few times to clean c

UPDATE The reason for the board count in the wave when there are no boards is due to operators leaving racks with empty PCB slots. The input feed sensor is a little bit more in the center of the conveyor whereas the output feed is a slightly closer t

We found repeated pad lifted after different SMT Reflow temperature (eg: 243 deg C and 233 deg C) at an isolated slot. The PCB Supplier had claimed that such condition is acceptable as per IPC 600H Clause 3.3.2 (Cross Sections) - eg: Acceptable - C
