In order to solve the above problems, an in-mold electronic (IME) component has proposed. The IME component is formed by sealing a circuit board and an electronic component on the circuit board in a plastic component through an injection molding process. In order to electrically connect the electronic component sealed in the plastic component to external components, it is generally necessary to lead the circuit board and a printed circuit on the circuit board out of the plastic component by arranging connecting cables, and bend it to a rear surface of the IME component, to facilitate the electrical connection to the external components. However, in a process of forming the IME component, a high-temperature injection molding process is required to be performed, and thus a substrate of the circuit board is easy to age and become brittle. Therefore, the circuit board corresponding to the wiring and the printed circuit on the circuit board are prone to brittle fracture when bent, resulting in failure of the electrical connection to the external components.

In order to solve the above problems, an IME component is provided.

In addition, as shown in <FIG>, the second film layer <NUM> is provided with a via hole <NUM>. The via hole <NUM> is filled with a conductive material <NUM>. The lead-out terminal <NUM> includes a flexible printed circuit (FPC) <NUM> and the conductive material <NUM> filled in the via hole <NUM>. One end of the conductive material <NUM> is electrically connected to the circuit layer <NUM>, and the other end of the conductive material <NUM> is electrically connected to the FPC <NUM>, such that the electronic component <NUM> sealed in the plastic layer <NUM> can be electrically connected to the external components sequentially through the circuit layer <NUM>, the conductive material <NUM> in the via hole <NUM>, and the FPC <NUM>.

In an embodiment, the circuit layer <NUM> may be made of conductive silver paste, conductive carbon paste, or conductive copper paste, but is not limited hereto.

Firstly, the decorative layer <NUM> is printed on a side of the first film layer <NUM>, and then, the via hole <NUM> is formed in the second film layer <NUM> by laser or computer numerical control (CNC) process, and then, the conductive material <NUM> is filled in the via hole <NUM> by double-sided printing. Then, the circuit layer <NUM> is printed on the second film layer <NUM>, and the transparent conductive layer is provided on the circuit layer <NUM>. Then, the transparent conductive layer is patterned by etching or other processes to form the touch unit <NUM> electrically connected to the circuit layer <NUM>. Then, pins of the LED lamp are connected to the circuit layer <NUM>, such that the circuit layer <NUM>, the display unit <NUM> and the touch unit <NUM> are all integrated on one side of the second film layer <NUM>. Then, the second film layer <NUM> is processed according to specific requirements. For example, the second film layer <NUM> can be bent into a curved surface, such that sizes and shapes of the second film layer <NUM> and the functional module <NUM> on the second film layer <NUM> can meet specific size and shape requirements. Then, the first film layer <NUM> and the second film layer <NUM> are provided on an inner surface of a mold cavity of a mold.

In addition, the circuit layer <NUM>, the display unit <NUM>, and the touch unit <NUM> on the second film layer <NUM> are sealed in the plastic layer <NUM> through the plastic layer <NUM>, such that the appearance structure of the IME component is lighter and thinner and is not detachable, and has advantages of moisture resistance, weather resistance, impact resistance and the like.

The transparent conductive layer is patterned by etching or other processes to form the touch unit <NUM> electrically connected to the circuit layer <NUM>. Then, pins of the LED lamp are connected to the circuit layer <NUM>, such that the circuit layer <NUM>, the display unit <NUM> and the touch unit <NUM> are integrated on one surface of the first film layer <NUM>. Then, the first film layer <NUM> is processed according to specific requirements. For example, the first film layer <NUM> is bent into a curved surface, such that sizes and shapes of the first film layer <NUM> and the functional module <NUM> on the first film layer <NUM> can meet the specific size and shape requirements.

In addition, the circuit layer <NUM>, the display unit <NUM>, and the touch unit <NUM> of the functional module <NUM> are sealed in the plastic layer <NUM> through the plastic layer <NUM>, such that the appearance structure of the IME component is lighter and thinner and is not detachable, and has advantages of moisture resistance, weather resistance, impact resistance and the like.
