Description

Technical Field

[0001] The utility model belongs to the technical field of packaging carrier plate processing, and in particular relates to a plate warping correction device suitable for packaging carrier plates. Background Art

[0002] In the electronics manufacturing industry, the package substrate is one of the key components, and its flatness directly affects the performance and reliability of electronic products. Board warpage is the bending or warping of the package substrate caused by various factors such as materials and processes during the production process. It will not only affect the processing accuracy of the package substrate, but also cause difficulties in the subsequent assembly process and reduce product performance. At present, the method of correcting the board warpage of the package substrate mainly relies on special anti-straightening equipment, which releases stress by heating and pressing the substrate to achieve the effect of board warpage correction. However, traditional heating and pressing methods may not be able to completely correct the board warpage problem of the substrate, especially in the face of complex or severe board warpage situations, the effect is even more limited; and the use of special anti-straightening equipment usually requires high purchase and maintenance costs.

[0003] In the prior art, there is a device and method for flattening the warping of a printed circuit board with a publication number of CN106211581A. The device includes at least one laminating film and at least two steel plates. When working, the printed circuit board and at least one laminating film are clamped between the two steel plates, and the laminating film is located between the printed circuit board and one of the steel plates. The laminating film and the printed circuit board are placed between the steel plates, and the printed circuit board is heated and pressurized, and then cooled to obtain a flattened printed circuit board. The printed circuit board is heated to more than 200 degrees and maintained for a period of time, and vacuum is simultaneously drawn to make the steel plates, the laminating film and the printed circuit board in close contact. However, the device adopts a heating and flattening method, which increases energy consumption and cost on the one hand, and is difficult to maintain. On the other hand, the heating needs to be continued for a period of time, which limits the production efficiency. Utility Model Content
