1. A method for manufacturing a low-melting-point metal device is characterized by comprising the following steps:

  • providing a packaging film and a substrate;

    manufacturing a low-melting-point metal pattern on the packaging film;

    compounding the packaging film with the low-melting-point metal pattern and the base material;

    the surface of the packaging film, on which the low-melting-point metal pattern is manufactured, faces the substrate;

    the low-melting-point metal is not adhered to both sides of the packaging film, and the manufacturing of the low-melting-point metal pattern on the packaging film comprises the following steps;

    selecting an ink which can be adhered to the packaging film and the low-melting-point metal;

    printing ink patterns on the surface of the packaging film by using the printing ink;

    curing the ink on the surface of the packaging film;

    and printing the low-melting-point metal on the surface of the packaging film, and only covering the low-melting-point metal on the printing ink pattern to obtain the low-melting-point metal pattern.
