Claim 0:
1. A method for packaging a COF, comprising:
S1, providing a flexible circuit substrate to be packaged and forming a plurality of first pins on a circuit surface of the flexible circuit substrate, and providing a chip to be packaged and forming a plurality of second pins on the chip to be packaged;
S2, arranging to keep the circuit surface of the flexible circuit substrate always facing downwards, arranging to keep a surface of the chip to be packaged, where the second pins matching the first pins are arranged, always facing upwards, and arranging the first pins on the flexible circuit substrate and the second pins on the chip to be packaged, both of which are matched with each other, to be opposite to each other; and
S3, applying a top-down pressure to the flexible circuit substrate and/or applying a bottom-up pressure to the chip to be packaged, and simultaneously heating at high temperature to solder the first pins and the second pins in a fused eutectic manner.
