Abstract:
A micro solder pot includes a dielectric substrate having at least one hole formed therein, a conductive coating coupled to the interior of the hole, and at least one heat transfer pad spaced from the hole in thermal communication with the conductive coating of the hole. When the heat transfer pad is exposed to a heat source, the conductive coating inside the hole is heated. The micro solder pot may also include a thermally activated conductive material disposed within the hole. When the heat transfer pad is exposed to a heat source, the thermally activated conductive material becomes liquidus such that a component can be inserted into the liquidus material. When the heat source is removed, the thermally activated conductive material cools to couple the component to the conductive coating in the hole.
Abstract:
A structure for attachment of a shield case to a circuit board. Electronic components are mounted at one face of the circuit board. The shield case is for covering the electronic components and blocking electromagnetic waves. The attachment structure includes toe portions, formed to protrude from the shield case, and holes formed in the circuit board, at which the toe portions can be inserted. The toe portions are fixed to the circuit board by being inserted into the holes and soldered to soldering lands at the other face of the circuit board. Thus, it is possible to prevent solder balls and solder flux entering the shield case, it is further possible to reserve space for soldering lands, with sizes that are required for fixing of the shield case, at a rear face of the circuit board, and it is possible to attach the shield case to the circuit board strongly.
