NOVELTY - Preparing graphene-doped copper bonding wire comprises (i) mixing the simple substances of each component according to ratio of the elements of the copper bonding wire, grinding, and sieving to obtain mixed metal powder, taking graphene oxide, and mixing with the mixed metal powder to obtain molten mixed powder, (ii) preparing the copper alloy ingot of fixed size after melting molten mixed powder, and preparing semi-finished wire with a diameter of 0.1-0.2 mm through rough drawing, middle drawing and fine drawing of the gold alloy ingot, (iii) placing the semi-finished product wire into the aqueous solution of the reducing agent for heating and washing, drying and fine pulling to 0.07-0.15 mm, entering into the aqueous solution of the reducing agent for heating and washing, finally entering into the aqueous solution of the reducing agent, heating and washing, and drying, and (iv) heating filament to 200-350℃ under the protection of nitrogen, annealing, washing and drying. USE - The method is useful for preparing graphene-doped copper bonding wire. ADVANTAGE - The method reduces the micro-crack generated in the filament in the cold-drawing process.
