    Abstract: There is disclosed a method, system, and screen for reducing solder voids on circuit boards. In an embodiment, there is provided a method of reducing solder voids on a circuit board, comprising: locating via holes provided at a conductive landing pad; and covering at least some of the via holes with a coating, whereby gases from the covered via holes are prevented from expanding and forming voids. In another embodiment, the method further comprises covering the location of at least some of the via holes in a pattern of strips, whereby more of the via holes may be covered by the coating while reducing areas of the conductive landing pad covered by the coating. In another embodiment, the coating and removal process may be performed at the same time as when all other areas of the circuit board are coated and removed, such that a separate manufacturing step is not required.

    Abstract: [PROBLEMS] To promote thinning of a surface illuminator while realizing higher and more uniform luminance by dissipating heat from a point light source more efficiently. [MEANS FOR SOLVING PROBLEMS] A heat dissipation path is constituted to transmit heat generated from a point light source (3) to a metallic heat dissipation plate (5a) through an electrode terminal (3a) of the point light source (3), a land portion (12) on the front surface (10F) of an FPC (10), a through hole (16) of a conductor pattern (14) and a high heat conduction resin (18). The path for efficiently dissipating heat from the conductor pattern (14) of the FPC (10) to the metallic heat dissipation plate (5a) is widened and a direct heat dissipation area is also secured sufficiently. Especially, even when a large current LED is employed in the point light source (3), sufficient heat dissipation effect can be attained. Since the degree of freedom of the wiring pattern and outline of the FPC (10) is not different from that of conventional FPCs, the request for thinning the surface illuminator can be met sufficiently.

On a surface of a wiring substrate, a pair of lands face to each other, and two wiring line is connected to the land, respectively. A mounting side outside electrode of a light emitting component is connected to a lead frame to which a light emitting element is die-bonded, and a non-mounting side outside electrode is connected to a lead frame which is connected to the light emitting element through a bonding wire. And, the mounting side outside electrode is bonded to the land by solder, and the non-mounting side outside electrode is bonded to the land by solder and thereby, the light emitting component is mounted on the wiring substrate. A line width of the wiring line at a side to which the mounting side outside electrode of the light emitting component is soldered is made to be larger than a line width of the wiring line at a side to which the non-mounting side outside electrode is soldered.
