| description | The preparation method comprises the following steps: mixing an alcohol ether low-boiling-point solvent with a high-boiling-point solvent to prepare a mixed solvent, adding a dispersing agent, a wetting agent and a coupling agent into the mixed solvent, mixing, then adding submicron spherical silver powder, stirring, and centrifugally mixing, thereby obtaining the low-temperature curing conductive silver paste for laser transfer printing. The preparation method comprises the following steps: firstly, preparing a silver paste solution, then adding resin, a flexibilizer, an initiator, a latent accelerator and an inhibitor for centrifugation, finally adding micron-sized flake silver powder, micron-sized spherical silver powder and modified silicone oil, and mixing by using a three-roller machine to obtain the finished silver paste. The formula is improved, so that the existing technical problems of high bulk resistance, difficult demolding, many residues and the like are solved; the template prepared by the meth |
