  • Publication number: 20100015362
    Abstract: An apparatus for electroless plating includes a plating bath containing an aqueous metal salt solution, and a magnetic field generator for generating a magnetic field. An object to be plated is immersed in the solution. The magnetic field generated by the magnetic field generator increases the level at which the metal ions are attracted to a surface of the object. Therefore, a layer of plating of good quality may be formed at a rapid rate.

  • Patent number: 7576437
    Abstract: Example embodiments may be directed to a printed circuit board having an insulating substrate, pads disposed on the surface of the insulating substrate, a solder resist, and a solder moving portion. Leads of a semiconductor package may be mounted on the insulating substrate. The pads to which the leads of the semiconductor package are connected may be disposed on the surface of the insulating substrate. The solder resist layer may cover the insulating substrate, but may also contain openings exposing at least a portion of the pads to which the leads of the semiconductor package are connected. During the process by which each semiconductor lead is connected to a pad, the solder moving portion on the pad may allow an adhesion solder coating each of the leads of the semiconductor package to move towards a shoulder portion of the semiconductor package leads.

  • Patent number: 7518873
    Abstract: A heat spreader includes a heat sinking plate and a pressure clip. The heat sinking plate radiates the heat away from a heat source. The pressure clip fixes the heat sinking plate to the heat source. The pressure clip includes a spine (pressing part), one or more ribs and hook parts. The spine is arranged on the heat sinking plate. The one or more ribs extend from the spine and contact the heat source. The hook parts extend from the spine and are supported by the heat source. The pressure clip further includes mounting parts that couple the spine to the hook parts. A bending space is formed between the spine and the heat sinking plate. The heat spreader may be attached to a printed circuit board (PCB) with, e.g., a one-touch method, so that assembling processes of the memory module may be automated.

  • Patent number: 7280233
    Abstract: For an automatic defect inspection of an edge exposure area of a wafer, an optical unit supplies a light beam onto the edge portion of a wafer and a detection unit detects light reflected from the edge portion. The detection unit converts the detected light into an electrical signal to transmit the electrical signal to a processing unit. The processing unit analyzes the electrical signal to measure the reflectivity of the edge portion, compares the measured reflectivity with a reference reflectivity, and calculates the width of the edge exposure area. The processing unit compares the calculated width with a reference width to detect any defect in the edge exposure area.
