The laminar article for electrical use comprises a plurality of superposed first metal laminations fixed together. Each of the first laminations is provided with at least one fastener projecting from a first surface thereof and defining a recess in its opposite side. Each fastener of one lamination is arranged to fit into a recess of an adjacent lamination. The article presents second laminations interposed between at least two adjacent first laminations fixed together. The second laminations are provided with through apertures which are traversed by the fasteners which fix the adjacent first laminations together. The method consists of die-cutting a plurality of laminations from a metal sheet, rotating the die-cut laminations and superposing them, to then fix them together in predetermined manner. The laminations can be die-cut with a reference axis thereof rotated through a predetermined angle about a reference axis of the sheet metal, to limit the rotations to be imposed on the laminations during their mutual fixing.

A universal solder pad is used with a plurality of SMD components having different sizes. Each SMD component includes a first conductive part and a second conductive part. The universal solder pad includes a first pad unit and a second pad unit. The first and second pad units are electrically connected to the first and second conductive parts of the SMD component, respectively. Each of the first and second pad units includes a main portion and a first extension portion. The first extension portion is extended from a first sidewall of the main portion and includes a first border, a second border and a third border. The second border and the third border of the first extension portion are parallel with each other for facilitating alignment of the first and second conductive parts of the SMD component with respect to the first pad unit and the second pad unit.

A stringed musical instrument, such as a guitar, whereby the lower end of the strings are anchored to the soundboard itself with one or more of the string anchors being positioned past the bridge. This arrangement provides an offset of the lateral compressive forces to the entire soundboard, therefore allowing the soundboard to vibrate more freely in response to the string vibration, and creating an acoustical perpetuating effect. Due to the inherent strength to this design, internal soundboard bracing can be minimized in weight and size as well, which offers a fuller and louder sound, with an increase in sonic balance and sustain. The string instrument also includes a split bridge design with the bridge body secured on the soundboard and having a saddle thereon for providing a contact point with the strings and a string retainer body secured separately from the bridge body on the soundboard and positioned behind the bridge body having directing means to guide each string.

An electrical heating device, which includes a housing, in which at least one heat generating element with at least one PTC element and electrical strip conductors abutting oppositely situated lateral faces of the PTC element and a plurality of heat dissipating elements arranged in parallel layers are accommodated, which are held abutted on oppositely situated sides of the heat generating element. An electrical heating device according to the invention and which fulfils the practical requirements, in particular with high voltage operation in an improved manner has at least one heat dissipating element which is situated, with the intermediate positioning of an electrically insulating layer, on the assigned heat generating element and can be electrically connected to a ground potential.
