However, the horizontal plug-in machine does not have an automatic material supplementing function, and when a bad component is inserted, the operator needs to manually supplement the component after the bad PCB is inserted. The operator often forgets to take out the bad board for repair, resulting in the flow of bad PCBs in the plug-in process to the next process.
