Abstract:
The invention concerns a solder spacer comprising an elongate body (102) having one end provided with a tapped hole (104) and an opposite end provided with a transverse support surface (106) from which a smooth centring pin (103) extends protruding, the pin (103) comprising a longitudinal outer passage (108) extending over a least a portion of the length of same to the transverse support surface (106), allowing a molten soldering paste to rise by capillarity to the transverse support surface (106). The invention also concerns a module (112) comprising such a spacer.
Abstract:
First and second tapered holes are provided at facing positions of the first and second circuit boards. The elastic spacer including first and second spacers is attached between them to couple the two in parallel and thereby facilitate attachment of the two to a back panel. The first spacer is provided at one end part with a tapered part which fits with the first tapered hole and the second spacer is provided at one end part with a tapered part which fits with the second tapered hole. A spring is inserted between the two spacers. The first spacer is fit in the tapered hole and fastened by a screw to the first circuit board. The second circuit board is fastened by a screw to the first spacer in a state fitting the second tapered hole over the second spacer with the second circuit board approaching the first circuit board.
Abstract:
A flexible printed circuit board, in particular for connecting electrical and/or electronic components, includes a fuse conductor track (10). The fuse conductor track has a conductor width (B1) formed on the flexible printed circuit board (1). The fuse conductor track (10) has a taper (12) in a fuse area (11) of the fuse conductor track (10), at which the fuse conductor track (10) has a fuse width (B2) which is smaller than the conductor width (B1) of the fuse conductor track (10) outside the fuse area (11).
Abstract:
A step etched metal electrical contact including a main body formed from a metal sheet defining a metal tab sized to match a die/device terminal and an electrical clearance aperture, electrical clearance trench, and/or an electrical clearance gaps. A heat sink may be combined with the step etched metal electrical contact to provide double sided module cooling for increased thermal performance of power modules.
Abstract:
According to exemplary embodiments, a tapered surface interconnect is formed on a printed circuit board (PCB). A compliant pin of an electrical connector may be coupled to the tapered surface interconnect and soldered thereto. The surface interconnect may be formed by drilling through one or more layers of the PCB. The depth of the surface interconnect may be shorter than a height or a thickness of the PCB. The surface interconnect may have a tapered side wall to allow for a better fit with a tapered compliant pin. The inclination of the side wall of the surface interconnect may be linear or concave. The intersection between the tapered sidewall and the bottom of the surface interconnect may be rounded to minimize pin insertion issues and may allow for easier solder flux evacuation. The compliant pin may be soldered into place upon being coupled to the tapered surface interconnect.
Abstract:
A circuit board assembly includes a printed circuit board and a component. The printed circuit board includes a plated thru-hole through the printed circuit board. The component includes a lead to interconnect the component to the printed circuit board. The lead is formed to define an opening through the lead. The lead is placed into the plated thru-hole such that at least part of the opening is within the plated thru-hole. The lead is laser welded to the plated thru-hole.
