An embodiment of the present invention provides a printed circuit board maintenance platform, including a workbench and a heating device, wherein the upper surface of the workbench is used to hold a printed circuit board, and the heating device heats a preset area of the printed circuit board, The preset area contains via holes, and the interior of the via holes is filled with resin, and the surface of the resin has depressions. When in use, keep the depression of the resin upward and heat it, the resin in the via hole will soften and expand outward, thereby reducing the volume of the depression on the surface of the resin, drop the resin above the resin in the via hole, and cool During the process, the resin in the via hole shrinks inward, and then gradually sucks the resin on the printed circuit board outside the via hole into the via hole, reducing the volume of the depression when the resin is dripped in, thereby avoiding the resin in the via hole when dripping the resin. Air bubbles are generated between the resin and the dripped resin, which improves the product quality.
Description
technical field [0001] The invention relates to the technical field of printed circuit board manufacturing, in particular to a printed circuit board inspection stand. Background technique [0002] The printed circuit board is the support body of the electronic components and the carrier of the electrical connection of the electronic components. Via holes with different diameters are arranged on the printed circuit board, so that the electrical connection lines on the printed circuit board can be connected between layers. In the actual production process, the via holes of the printed circuit board need to be plugged. , so how to plug the vias on the printed circuit board has become a research hotspot. [0003] In the related art, plugging is generally performed by filling resin oil into the via holes. Specifically, the resin oil is heated, and then the resin oil is dropped into the via hole, and the via hole can be filled after the resin oil is cooled. [0004] However, du...
