Patent ID: 7615860

Claim:
A rigid-flex printed circuit board (PCB) with a weakening structure, comprising a rigid printed circuit board (RPCB) and a flexible printed circuit board (FPCB) that are bonded together form a complete circuit board; the RPCB including: a connection section having a first lateral edge and an opposite second lateral edge; a first section extended from the first lateral edge of the connection section with a weakening structure formed between the first section and the connection section, and having a FPCB bonding side, the weakening structure including a groove extending entirely from an end to an opposing end of the connection section; and a second section extended from the second lateral edge of the connection section with a weakening structure formed between the second section and the connection section, and having a FPCB bonding side; and the FPCB including: a bending section corresponding to the connection section on the RPCB, and having a first lateral edge and an opposite second lateral edge; a first section extended from the first lateral edge of the bending section, and having a RPCB bonding side corresponding to the FPCB bonding side of the first section of the RPCB; and a second section extended from the second lateral edge of the bending section, and having a RPCB bonding side corresponding to the FPCB bonding side of the second section of the RPCB.
