Abstract
An apparatus for manufacturing plug and the manufacturing method is described. The method comprises providing a baseplate on a bottom surface of a sealed printing chamber. The printed circuit board and a stencil on the baseplate are sequentially mounted on the baseplate. Several cameras are used to align the holes of the printed circuit board and the stencil. A proper amount of preheated paste is printed on the stencil. The sealed printing chamber is adjusted to a first pressure to perform a paste-printing step for filling the hole of the printed circuit board with paste. The sealed printing chamber is adjusted to a second pressure. The sealed printing chamber is adjusted to a third pressure to perform a scraping step for remove redundant paste.
