Description

Technical Field

[0001] The utility model relates to the technical field of multi-layer circuit board production, in particular to a vacuum laminator for multi-layer circuit board production. Background Art

[0002] In the production process of multi-layer circuit boards, vacuum laminators are widely used to process the production of multi-layer circuit boards. The production method of multi-layer boards generally starts with making the inner layer graphics first, and then using the printing and etching method to make a single-sided or double-sided substrate, and incorporate it into the specified interlayer, and then heat, pressurize and bond it. As for the subsequent drilling, it is the same as the plated through-hole method of the double-sided board. Vacuum laminators are also used in the production process of multi-layer circuit boards.

[0003] After searching, the existing Chinese patent announcement number is: CN214203720U, which provides a fast vacuum laminator. The patent provides a vacuum container between the vacuum pump and the cavity, and a control valve is provided on the pipeline connecting the vacuum container and the exhaust hole. Before the upper cover is closed, the control valve is closed to exhaust the vacuum container. When the upper cover is closed, the control valve is opened to vacuum the cavity. Since the vacuum container is exhausted in advance, when the control valve is opened, the gas in the cavity quickly flows into the vacuum chamber, reducing the amount of air pumped to the cavity by the vacuum pump, thereby reducing the process time of exhaust and improving efficiency. Since the control valve is relatively cheap, the exhaust time is saved without increasing the cost, which greatly increases the cost performance of the laminator.

[0004] Although the above patent can save vacuum time and greatly increase the cost performance of the laminator, the above fast vacuum laminator still has the following problems: after the production of the multi-layer circuit board is completed, the multi-layer circuit board needs to be taken out. Since it is processed by heating and pressurizing, it is inconvenient to take it out and wastes time.

[0005] In view of the above problems, a vacuum laminator for producing multi-layer circuit boards is proposed. Utility Model Content
