Modern SMT machines may operate with 300–400 feeders per machine. Operators are tasked with monitoring multiple feeder banks, material states, and production metrics simultaneously.
High feeder density introduces:
Human factors research shows that as cognitive load increases:
Splicing methods that require high alignment precision or multi-step verification are increasingly vulnerable under these conditions.
Reliability becomes a function of:
Human-machine interaction must be treated as part of the engineering system, not as an external variable.
When cognitive load is high:
Engineering solutions that accommodate human limitations outperform those that assume ideal execution.
Across all environments, SMT tape splicing reliability emerges from the interaction of:
Treating splicing as a uniform task ignores the variables that most strongly determine performance outcomes in real manufacturing systems.
