[0003] At the present stage, the method for observing and judging whether the vias are filled completely is as follows: Before filling the vias, a special piece of paper is placed under the vias. After the vias are filled, there will be an imprint of the paste after filling on the paper. At this time, the paste imprint points on the paper are used to judge whether the vias are completely filled. Then, marks are made at the abnormal via positions, and finally, drying treatment is carried out.
