Discrete electronic component and related assembling method

Abstract

The present invention relates to a substantially package-like discrete electronic component of the type comprising a power electronic circuit, a body or casing, substantially parallelepiped, and electric connecting pins connected inside the body with said circuit and projecting from said body for an electric connection on the electronic printed circuit board. The body has a heat dissipating header having at least one surface emerging from the body and laying on a plane whereas the pins project from the body for a first section initially extended parallel to the plane. Advantageously a pair of pins has a substantially U-shaped bending, after the first section parallel to the plane for allowing a more stable bearing of the component during the step of welding to a heat dissipating intermediate die.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation of U.S. patent application Ser. No. 11 / 053,478 filed on Feb. 8, 2005.FIELD OF APPLICATION [0002] The present invention relates to a discrete electronic component such as for example a power switch. The invention also relates to a related assembling method of this discrete electronic component on an electronic board. [0003] During recent years the use of these discrete electronic components in printed circuit boards has undergone a considerable increase being the same simple to be controlled and reliable in the applications. PRIOR ART [0004] As it is well known, the substantially package-like discrete electronic components comprise a power electronic circuit assembled on a small metallic frame, wherein some electric connecting pins are defined, and a protecting body or casing realised with insulating plastic material, for example an epoxy resin. The connecting pins project from said body and they allow,...

AI Technical Summary

Benefits of technology

The component is securely fixed and aligned on the die, facilitating efficient and automated assembly, reducing manual labor costs and ensuring correct pin alignment, thus simplifying the assembly process and improving the reliability of the assembly process.

Problems solved by technology

Although advantageous under several aspects, and substantially meeting the aim, this first known technical solution has a drawback hereafter underlined.

The assembly thus described cannot occur mechanically, in fact the clips will have to be manually placed by an operator and this with a considerable expenditure of time and increased costs.

This would make the operation itself vain and useless in fact the obtained component could not be installed on the board since there would not be correspondence between the pins of the discrete electronic components and the printed circuit.
