    Abstract:  回路基板34と導電体60bとの上に配線72が形成される際に、インクジェットヘッド24により、金属微粒子を含有する金属インク70が、回路基板と導電体とに跨って塗布される。そして、塗布された金属インクにレーザ照射装置26によりレーザが照射される。これにより、レーザ照射された金属インクが焼成され、配線72が形成される。この際、回路基板の上の金属インクには、回路基板の素材である樹脂に応じた単位面積当たりのレーザ照射量に相当するレーザが照射され、導電体の上の金属インクには、導電体に応じた単位面積当たりのレーザ照射量に相当するレーザが照射される。これにより、回路基板の上の金属インクと導電体の上の金属インクとが適切に焼成され、回路基板と導電体とに跨って適切に配線を形成することが可能となる。

    Abstract: A method of applying viscous media on a substrate is disclosed. In the method, the substrate is provided, which is arranged for mounting of electronic components thereon. Further, flux is provided on a deposit of solder paste, which deposit is arranged at a predetermined position on the substrate. The flux is provided by a non-contact dispensing process, such as jetting. By providing flux on the deposit prior to reflow, the risk of quality related issues, such as e.g. graping, advantageously is reduced.

    Abstract: To provide an electronic component placing apparatus and an electronic component mounting method that can prevent a cold joint from occurring when an electronic component likely to cause warp deformation is mounted by means of soldering. In the electronic component placing apparatus for placing the electronic component 16 with a plurality of solder bumps 16a formed on a lower surface on a board, a film 7a having a film thickness distribution for transferring a desired transfer amount of solder paste according to a state of warp deformation to each of the plurality of solder bumps is formed in a paste transfer unit 24, based on the component warp information indicating the state of warp deformation in a reflow process of the electronic component. Thereby, it is possible to prevent a cold joint from occurring when the electronic component likely to cause warp deformation is mounted by means of soldering by additionally supplying a just enough amount of solder to each solder bump 16a.

    Abstract: A system and a method are provided for ink-jet printing a solderable conductive pad onto a substrate. The system comprises at least one print head and a curing station for curing an ink deposited onto the substrate. The system is configured to: deposit at least a first layer of a first ink onto the substrate; cure the first layer of the first ink; deposit at least an intermediate layer of a second ink on top of the cured first layer of the first ink; cure the intermediate layer of the second ink; deposit at least a last layer of the first ink on top of the cured intermediate layer of the second ink; and cure the last layer of the first ink. The first ink has a relatively high conductivity. The second ink has a relatively low conductivity. The first layer, the intermediate layer, and the last layer may be arranged such that when solder is applied to the last layer, the solder is prevented from leaching through to the first layer.

    Abstract: A circuit board ( 100) includes at least one trace (104a-d, 205, 305) having at least one heat spreader (120-123, 220, 223, 3 10) disposed thereon, the heater spreader being formed of a solidified paste, such as a paste that includes a mixture of binder particles and filler particles, or a solder paste. As an example, the heater spreader may be configured to increase a cross-sectional area of a portion of the trace, thereby improving heat flow along that portion of the trace. Alternatively, the heater spreader may be configured to increase the surface area of the trace, thereby increasing heat dissipation from the circuit board. As another example, the heat spreader may be disposed between the trace and a semiconductor device ( 108-1 10, 308) and thereby function as a heat sink for the device.
