Abstract:
In this mounting structure and method for a surface mounted type electronic component (41), the component (41) has at least one terminal (36,34,36',34') which protrudes from its bottom surface and which terminates in a foot portion (36a,34a,36'a,34'a) for being soldered to a printed circuit board (43). Also, a projection (5) extends from this bottom surface of the electronic component for a distance (B) somewhat less than the amount by which the terminal (36,34,36',34') projects from it. This projection is provisionally secured by adhesive (45) to the printed circuit board (43) with the foot portion (36a,34a,36'a,34'a) of the terminal (36,34,36',34') overlaying that circuit portion (44) to which it is to be soldered, and then subsequently this terminal foot portion (36a,34a,36'a,34'a) is soldered to this circuit portion (44). The projection (5) may extend from a central portion of the bottom surface of the component (41), or may be provided in plurality as extending from central portions of edges of said bottom surface. And the end of the projection may be roughened.

Abstract:
The invention relates to a method for producing a device comprising a transponder antenna connected to contact pins, said method comprising the steps of: providing or producing an antenna (3) with terminal connections (7b, 8b) in contact with a substrate, placing the contact pad (5, 6) on the substrate ad connecting the same to the terminal sections of the antenna (7b, 8b), the connection being produced by means of a soldering (38) by introducing energy between the pads (5, 6) and the terminal sections (7b, 8b). The method is characterised in that the pads (5, 6) are placed such as to provide a surface (40) facing an antenna terminal connection section (7b, 8b), said section being arranged on the substrate (2, 2b, 2f) and the soldering energy being directly applied to the pads (5, 6). The invention also relates to the device obtained.
Abstract:
An apparatus for mounting on a circuit board is provided. The apparatus may include a circuit board mount packaging and a battery. The circuit board mount packaging may include a cavity, a first internal lead, and a second internal lead. The first internal lead may be connect to a first external pin and the second internal lead may be connected to a second external pin. The battery may be disposed within the cavity of the circuit board mount packaging. The battery may comprise an anode and a cathode. The anode may be wire bond connected to the first internal lead and the cathode may be wire bond connected to the second internal lead.
Abstract:
An interposer configured for connecting offset arrays of signal pads on parallel surfaces. Contacts of the interposer have mating portions with multiple beams. One of the beams makes contact with a pad on a first of the surfaces and is deflected when the surfaces are pressed together with the interposer between them. A second of the beams is positioned so that the first beam presses into that second beam as the first beam deflects. The second beam may contact a central location on the first beam. An electrical path through the contact from a pad on the first surface to a pad on the second surface may be shorter when the first beam is pressed into the second beam than through the first beam alone. A shorter path may improve signal integrity. Moreover, the spring force of the contact may be set by the second beam.

Abstract:
Methods for mounting a power amplifier (PA) assembly having an extended heat slug (11) are disclosed. According to one aspect, a method includes manufacturing a left side PCB (22a) and a right side PCB (22b). The method further includes sliding the left side PCB and the right side PCB inward (30) to encompass the PA assembly so that one of the left and right side PCB is in a position to contact a drain of the PA (13) and so that the other of the left and right side PCB is in a position to contact a gate of the PA (14).
