Zusammenfassung: | The invention discloses a copper deposition process for preparing a PCB (printed circuit board) by using a graphene material, and relates to the technical field of copper deposition processes, the process comprises the following steps: firstly, drilling a hole in the PCB, cleaning and drying the PCB in a cleaning box, soaking the PCB in a groove filled with a graphene solution for 40-60 seconds after drying, taking out the PCB, and washing and drying the PCB; carrying out micro-etching on the washed and dried PCB, cleaning, and then carrying out electro-coppering; wherein a preparation method of the graphene solution comprises the following steps: dissolving graphene powder and calcium carbonate powder in water, and uniformly mixing; according to the method, irregular tiny holes can be formed in the inner wall of the graphene layer, a part of the tiny holes exist independently, a part of the tiny holes communicate with one another, during copper electroplating, copper molecules enter the tiny holes and are co |
