The invention discloses a method of a plate-sticking test of a coverlay and a lamination machine used therefor. The uniform and constant pressure on the covelay is realized by using flatness and stress uniformity of the lamination machine, so that traditional ways of laminating the coverlay by using hand feel are changed. A separating tension of the coverlay is tested by using a universal tensile machine, and strength of the coverlay adhesiveness is shown by accurate values, so that traditional ways of relying on experience and feelings of testers are changed. Therefore, the method, by utilizing general testing and laboratory instruments, can simply and accurately test technical indicators traditionally difficult to access, and effectively quantify technical indicators previously unavailable to digitization.
