Abstract

The present invention provides a printing mechanism for raw ceramic chip through hole wall metallization. The mechanism comprises a printing platform with a big cavity, an external negative pressure source communicated with the big cavity, a mask piece and a support plate, the mask piece is movably arranged at the upper portion of the support plate along the vertical direction, and the mask piece is provided with a through hole being consistent to a raw ceramic chip; the support plate is arranged on the printing platform, a venthole corresponding to the through hole on the mask piece is arranged on the support plate, and absorption holes are arranged at other positions of the support plate; and one way of negative voltage of the negative pressure source is communicated with the venthole, and the other way of the negative voltage of the negative pressure source is communicated with the absorption holes. The printing mechanism improves the slurry uniformity at the raw ceramic chip through hole wall metallization and alleviates the phenomenon of slurry obstructing the through hole.

Description

technical field [0001] The invention relates to the field of printing machines in the multi-layer ceramic substrate manufacturing industry, in particular to a printing mechanism for metallizing the walls of through holes of green ceramic sheets. Background technique [0002] When metallizing the hole wall of the green ceramic sheet of the multilayer ceramic substrate, the printing mechanism for realizing the metallization of the hole wall is an essential part. At present, the method of metallizing the wall of the through hole of the green ceramic sheet is as follows: on the large cavity workbench, the green ceramic sheet is placed on the porous backing plate, and the through hole of the green ceramic sheet is together with the small holes of the porous backing plate. Corresponding to the shaft, the large cavity of the worktable is connected to the external negative pressure source. The green ceramic sheet is adsorbed to the porous pad by one negative pressure of the negative...
