[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnection. Because it is manufactured using electronic printing technology, it is called a "printed" circuit board. During the assembly process, small electronic components are first fixed onto the PCB using horizontal and vertical insertion machines. Then, the vertical insertion machine transports the assembled PCB to the placement slot on the placement frame. Workers then transfer the placement frame to a manual insertion assembly line, where operators manually place the PCB onto the assembly line. This process is called placement. Traditional placement is mainly done manually, which can easily contaminate the PCB and has low efficiency.
