preparation example Construction
[0031] The present invention also discloses the preparation method of the above-mentioned conductive silver paste for LTCC ceramic substrate, including:
[0032] (1) The polymer resin and the solvent are mixed according to a certain ratio and fully dissolved to obtain an organic vehicle. According to the formula, a certain proportion of polymer resin and solvent is dissolved at a certain temperature of 80°C-85°C for 1-2 hours to form a uniform and transparent fluid with a certain viscosity, which is an organic carrier.
[0033] In the present invention, the preparation of the organic carrier can be prepared by conventional methods in the field, for example, the following steps can be included: drying the polymer resin: placing the polymer resin in an oven at a constant temperature of 60°C-65°C for 8 -9 hours, so that the polymer resin is fully dried; the polymer resin and the solvent are mixed according to the proportion and fully dissolved to obtain the mixture: put the conta...
