Abstract:
1. A method of forming a plurality of protection circuit modules (PCMs) for a battery, the method comprising: positioning a flexible printed circuit board (FPCB) on a fixing surface wherein the FPCB includes a plurality of unit pattern forming regions that each define a main body and an external terminal; positioning chip circuit devices on the main body of the unit pattern forming regions of the FPCB so that a plurality of PCMs can be formed on the FPCB; connecting one or more internal terminals to the FPCB; positioning a protective layer over at least a portion of the FPCB so as to cover at least some of the components of the PCMs formed on the FPCB; and separating the FPCB from the fixing surface after the chip circuit devices and protective layer has been positioned on the FPCB so as to separate a plurality of individual PCMs from the fixing surface, wherein the one or more internal terminals are configured to be connected to one or more electrodes of a bare cell supplying electrical energy so that the internal terminals extend outward from the main body of the FPCB to a direction away from the protective layer and extend over an edge of the FPCB.
