Problems solved by technology
[0005] In this case, a process of individually compressing each terminal to the FPCB is required, which is not efficient in terms of productivity
Also, since the electrical connection between the FPCB and the connector is made using terminals compressed to the FPCB, there is a high risk of contact when vibration or shock is applied thereto
[0006] Also, even if one of the various terminals fails to make contact with the FPCB or a compression failure occurs during the terminal compression process, an error may occur in the voltage measuremen
