A method of manufacturing a printed circuit board (PCB) having embedded components. The method includes: forming a cavity in one side of a dielectric substrate; inserting a first component in the cavity such that an electrode thereof faces the one side of the dielectric substrate; mounting a second component on one side of the first component such that an electrode thereof faces the same direction as the electrode of the first component; forming a first dielectric layer on one side of the dielectric substrate such that the first dielectric layer covers the second component; and forming a second dielectric layer on the other side of the dielectric substrate such that the second dielectric layer covers the first component.

A method of manufacturing a wafer level package is disclosed, which may include: coating an insulation layer over one side of a semiconductor chip, on one side of which an electrode pad is formed, such that the electrode pad is open; forming a seed layer by depositing a conductive metal onto one side of the semiconductor chip; forming a rewiring pattern that is electrically connected with the electrode pad, by selective electroplating with the seed layer as an electrode; forming a conductive pillar that is electrically connected with the rewiring pattern, by selective electroplating with the seed layer as an electrode; and removing portions of the seed layer open to the exterior. By forming the rewiring pattern and the metal pillar using one seed layer, the manufacturing process can be simplified, whereby defects during the manufacturing process can be reduced and the reliability of the products can be improved.

摘要:
A method of manufacturing a package board is disclosed. The method is for manufacturing a package board that has a pad electrically connected with a component, and includes: forming an indentation, which is in correspondence with the pad, in one side of a first insulating layer; filling a metal paste in the indentation; mounting the component on the first insulating layer in correspondence with a location of the indentation; and hardening the metal paste. Using this method, damage to the component can be prevented during the forming of vias, as the component is mounted after filling paste in an indentation formed in an insulating layer.
摘要:
A method for forming metallurgical interconnections and polymer adhesion of a flip chip to a substrate includes providing a chip having a set of bumps formed on a bump side thereof and a substrate having a set of interconnect points on a metallization thereon, providing a measured quantity of a polymer adhesive in a middle region of the chip on the bump side, aligning the chip with the substrate so that the set of bumps aligns with the set of interconnect points, pressing the chip and the substrate toward one another so that a portion of the polymer adhesive contacts the substrate and the bumps contact the interconnect points, and heating the bumps to a temperature sufficiently high to form a metallurgical connection between the bumps and the interconnect points. Also, a flip chip package is made by the method. In some embodiments the metallurgical connection includes an alloy of gold and tin at the interface between the bumps and the interconnect points.
