Method of manufacturing printed circuit board with embedded electronic components positioned by using solder paste
A method of manufacturing a printed circuit board with embedded electronic components fixed by a solder paste includes: providing a carrier board with a copper foil layer on the carrier board, an insulating layer on the copper foil layer, and an opening on the insulating layer by laser; putting a solder paste into the opening to form a solder paste layer; performing a high-temperature reflow process of the electronic components on the solder paste layer until the solder paste layer is molten; curing the solder paste layer after cooling to fix the components to the center position of the opening; placing the copper foil layer below the electronic components and removing the solder paste layer; and performing copper plating and electroplating processes in an electroplating space to form a plating copper. The cohesion of the molten solder paste pulls the electronic components towards the center to eliminate position offset produced when the electronic components are installed.
