Cutting mold for rigid-flexible circuit board and method for forming the same

A cutting mold for removing two opposite superfluous rigid circuit boards from a rigid-flexible circuit board, comprising:

• a first moldboard;
• at least one first cutter connected to the first moldboard;
• at least one first barricade connected to the first moldboard, wherein the maximum vertical distance from the first barricade to the first moldboard exceeds that from the first cutter to the first moldboard;
• a second moldboard opposite the first moldboard, wherein the first and second moldboards move with respect to each other;
• at least one second cutter connected to the second moldboard and corresponding to the first cutter;
• and
• at least one second barricade connected to the second moldboard and detachably abutting the first barricade, wherein the maximum vertical distance from the second barricade to the second moldboard exceeds that from the second cutter to the second moldboard, and the first and second cutters cut the superfluous rigid circuit boards when the first and second moldboards move toward each other;
• wherein the rigid-flexible circuit board comprises a flexible circuit board, the difference between the maximum vertical distance from the first barricade to the first moldboard and the maximum vertical distance from the first cutter to the first moldboard exceeds half the thickness of the flexible circuit board, and the difference between the maximum vertical distance from the second barricade to the second moldboard and the maximum vertical distance from the second cutter to the second moldboard exceeds half the thickness of the flexible circuit board;
• and
• wherein at least one third cutter and at least one fourth cutter, wherein the third cutter is connected to the first moldboard and first cutter, the fourth cutter is connected to the second moldboard and second cutter, the maximum vertical distance from the third cutter to the first moldboard exceeds that from the first cutter to the first moldboard, and the maximum vertical distance from the fourth cutter to the second moldboard exceeds that from the second cutter to the second moldboard.
