To solve this problem, multiple integrated circuit devices have been installed. In a typical module, a plurality of integrated circuit devices such as a semiconductor package are connected to one or both sides on a printed circuit board (PCB). In view of good conductivity, modules are generally manufactured when multiple PCBs are moved along a conveyor belt. In particular, it is called a thin-plate type (such as the pcB system that is called ㈣, which undergoes the manufacturing process of the module, as known in the know-how. Each thin-plate type PCB has many independent PCBs, which are called chip-type coffee cuts.) : ^ * PCBs are connected to each other at their ends, leaving a central isolation space between adjacent independent pcBs. The final module manufacturing of a single independent PCB is obtained by cutting the connection part of the thin-film PCB after the completion of the process However, there are many problems with the use of thin PCBs. One of them is that the thin PCBs have several useless parts, such as connection parts or space. These useless parts need to hold the thin PCBs during the manufacturing process, However, it is not required in the final product. In addition, although one or more unexpected damages may be found in the independent p C b constituting the thin PCB during the manufacturing process, the damaged PCB will be difficult to remove and will The final processing step of the shore calendar. This is a major disadvantage in productivity. Therefore, in recent years, at the beginning of the module manufacturing process, multiple independent PCBs that do not need to connect parts or spaces have been provided.
