Patent ID: 7789989

Claim:
A method for manufacturing a rigid-flexible printed circuit board, comprising: providing a flexible substrate, the flexible substrate including a main portion and a peripheral margin portion, the main portion including a first laminating section and an exposed section; defining at least one slit in the flexible substrate along at least one first imaginary boundary line between the exposed section and the peripheral margin portion; providing a rigid substrate, the rigid substrate comprising a main portion and a peripheral margin portion, the main portion including a second laminating section having a similar shape to the first laminating section and an unwanted section having a similar shape to the exposed section; laminating the flexible substrate to the rigid substrate to obtain a laminated substrate in such a matter that the first laminating section is attached to the second laminating section to form a first section, the exposed section is attached to the unwanted section to form a second section, and the peripheral margin portions are attached with each other to form a third section, wherein the at least one slit is defined in the flexible substrate prior to the step of laminating the flexible substrate to the rigid substrate; removing the unwanted section to expose the exposed section; and cutting the laminated substrate along an imaginary boundary line between the first section and the third section to remove the third section.
