Claim 12:
13. A circuit board packaging method, comprising:
providing a circuit board, wherein the circuit board comprises a first base board, a plurality of electronic components, a plurality of conductive lines, and a plurality of conductive connection pads, wherein the first base board comprises a first base surface and a second base surface that are opposite surfaces of the first base board, and wherein the plurality of conductive connection pads are disposed on each of the first base surface and the second base surface;
providing a lead frame, wherein the lead frame comprises a plurality of frame units disposed in parallel in a first direction, wherein each frame unit of the plurality of frame units comprises a bezel that is hollow, a plurality of pins, and connecting ribs, wherein each pin of the plurality of pins comprises a first pin part and a second pin part that extend in a same direction and that are integrally formed, the first pin part is disposed in the bezel, the second pin part is connected and fastened to the bezel, and wherein the connecting ribs are connected between the first pin part and the bezel;
fastening and connecting the circuit board to the lead frame, wherein the circuit board is correspondingly disposed in a hollow part in the lead frame, and the plurality of conductive connection pads are correspondingly connected and fastened to first pin parts of the plurality of pins;
plastically packaging the circuit board and the first pin parts of the plurality of pins, to form a packaging casing; and
performing a cutting operation at positions of connecting ribs in pins in each frame unit of the plurality of frame units, so that the plurality of pins are separated from the lead frame, to obtain a plurality of packaged integrated circuit boards.
