[0002] With the rapid development of communications, electronics, and other related industries, the demand for surface acoustic wave products is increasing, and competition is becoming increasingly fierce. Therefore, to reduce overall costs, plastic laminates have become widely used in production. The thickness of the laminate materials currently used ranges from 0.15mm to 0.3mm. The components mounted on the laminates are also getting smaller and smaller, and the specifications of the components mounted are mostly 01005, which also requires high printing precision.

[0003] Currently, some very thin laminates are used in the production of surface mount technology, which poses great challenges for printing and mounting. For example, the laminates are difficult to fix during the production process, and the deformation and warping of the laminates are difficult to solve, making it impossible to meet the process requirements of surface mount technology, such as printing, mounting, and reflow soldering.
