Abstract:
A transmitter-receiver unit is disclosed wherein a frame is provided with solder-rise preventing means (H) between a circuit board (1) and retaining portions (4c), thereby preventing solder from rising up to the retaining portions. Thus, the engagement between engaging holes and the retaining portions is ensured in comparison with the prior art. The transmitter-receiver unit permits a cover to be mounted positively to the frame and is suitable for the reduction of size and weight.
Abstract:
Structures, materials, and methods to control the spread of a solder material or other flowable conductive material in electronic and/or electromagnetic devices are provided.
Abstract:
An electrical device for soldering to a circuit board with a solder includes a capacitor, a lead frame including a solder dam, and a solder joint electrically coupling the capacitor to the lead frame. The solder dam includes one of a physical barrier to flow or an area of reduced wettability to the solder. The solder dam is between the solder joint and the circuit board. The solder dam is on one or both of a lead portion and main portion of the lead frame. In one embodiment, the first solder dam extends substantially the full width of the first lead portion. The solder dam may be a barrier and/or include a metal oxide. A method of manufacturing the device includes soldering a lead frame to a capacitor with a solder and modifying a surface on the lead frame to include a physical barrier and/or an area of reduced wettability.
Abstract:
There are provided an electronic component module capable of increasing a degree of integration by mounting electronic components on both surfaces of a substrate, and a manufacturing method thereof. The electronic component module according to an exemplary embodiment of the present disclosure includes: a substrate; a plurality of electronic components mounted on both surfaces of the substrate; connection conductors each having one end bonded to one surface of the substrate using an conductive adhesive; and a molded portion having the connection conductor embedded therein and formed on one surface of the substrate, wherein the connection conductor may have at least one blocking member preventing a spread of the conductive adhesive.

Abstract:
A method of assembling a circuit board may include inserting a first electrical terminal into a first side of a circuit board, and applying a second layer of solder paste to a second side of the circuit board, the second side disposed opposite of the first side. The first electrical terminal may include a solder tab, a maximum length of the solder tab may be shorter than a minimum thickness of the circuit board, and if the first electrical terminal is inserted into the circuit board, the solder tab may extend at least partially into the circuit board without extending entirely through the circuit board. One or more electrical terminals with short and/or long solder tabs may be inserted into the second side of the circuit board and/or one or more electrical components may be attached to second side of circuit board.
