Siplace X4i placement machine is said to have a speed rating of 102,000 cph per IPC-9850, and a maximum theoretical performance rating of 135,500 cph. Features a dual conveyor, in which each of the two heads populates one board independently of the other, shortening travel between feeders and PCB. A third transport track moves PCBs through the machine to be processed in parallel on another machine. Another feature pushes two boards together on a single track and processes them as a single board.
