The NTA Belt FIFO Buffer is used as a buffer to store PCB from upstream machine. It uses belt segments to hold PCB over its complete length. When adding or extracting a PCB to or from the Buffer, a drive mechanism engages with the belt segment to smoothly transfer the PCB in or out. It can operate in First In First Out (FIFO), Last In First Out (LIFO), Loader, Unloader and Bypass mode.
