This is because some via holes may cause problems in subsequent surface treatment or assembly process if not filled. For example, during chemical nickel gold plating and other surface treatments, the chemical solution may remain in the via hole, affecting the performance of the board. Moreover, after hole-plugging, the surface of the circuit board can be made more flat, which is conducive to the installation of components and enhances the stability of the circuit board.
