The invention relates to a method for controlling expansion and shrinkage of lamination of multiple
layers of boards. The method comprises the steps that board incoming quality inspection is conducted, a dimensional
stability test is conducted, and a part number is selected according to a test result; according to relevant parameters, an expansion and shrinkage
library is established; inner films are produced, and measurement and statistics are conducted on the produced films;
punching is conducted on multiple
layers of boards which are not laminated; according to the thickness of each board, rivets with appropriate height are selected for riveting; the pattern is adjusted, the lamination conditions are set; lamination is conducted; holes are drilled through an X-
RAY target drilling
machine. Compared with the prior art, the method for controlling expansion and shrinkage of lamination of the multiple
layers of boards has the advantages that the demand for large-composition production is met, production cost is effectively reduced, the utilization ratio of the boards is increased, the production efficiency is improved, and the
rejection rate is reduced. Factors influencing control over expansion and shrinkage are controlled, the range of the influence caused by expansion and shrinkage is effectively narrowed, the error rate of drilling is effectively reduced, defective products and scrapped products caused by overall displacement of the multiple layers of boards are reduced, the drilling first-workpiece percent of pass is increased, and halt determination time is shortened.
