Abstract:
The invention relates to an electrically conductive wire (1) comprising two spaced solder balls (2) thereon and flux (4) in the space (3) between the solder balls for making a circuit connection between electrically conductive members on opposite surfaces of a substrate. The wire (1) is inserted in a through-hole of the substrate and soldered by a customary soldering process, like wave soldering.

In accordance with certain embodiments, an illumination system comprising a plurality of power strings features elements facilitating compensation for failure of one or more light-emitting elements connected along each power string.
Abstract:
Die Erfindung betrifft Leiterplatten, die untereinander durch flexible Leiterbahnen oder Jumper verbunden werden. Es ist wünschenswert, die Jumper in einem dem Lötprozess und in einem Schritt zusammen mit anderen SMD- und sonstigen Bauteilen auf den Leiterplatten in einem Reflow-Lötofen zu löten. Dazu sind bei der erfindungsgemäßen Leiterplatte (10), die üblicherweise mehrere Innenlagen (11) sowie innere Leiterbahnen (12) und äußere Leiterbahnen (13) aufweist, in der Stirnseite (18) seitliche Öffnungen (17) angebracht, die vorzugsweise metallisiert sind. Nach Ein- bzw. Aufbringen von Lotpaste können dort hineingesteckte Anschlußpins bzw. Anschlußdrähte (16) eines Jumpers (15) zusammen mit anderen Bauteilen auf der Leiterplatte (10) in einem Reflow-Lötofen verlötet werden.
Abstract:
The invention relates to a method of making an RFID tag comprising the steps of: a) providing a dielectric substrate (502); b) forming on said substrate an antenna circuit (515), said antenna circuit comprising more than one turn (515) and a first (521) and second (522) antenna terminals, said first terminal comprising an arm portion (5211) and a terminal end (5212), c) cutting out said dielectric substrate to form a dielectric tongue (540), d) bending said dielectric tongue so that a portion of said dielectric tongue is used as an insulating layer between said more than one turn and a conductive path between said first and second.
Abstract:
There is constructed a constitution such that a shunt resistor 30 is interposed in series with a portion capable of measuring an output current of a unidirectional power source portion 1 of a high frequency heating apparatus and a voltage generated at the shunt resistor 30 is outputted by a buffer 31. Further, an operational amplifier 3101 having a high input impedance is used for the buffer 31. Further, a diode bridge 101 and a semiconductor switching element 205 are fixed to a common heat radiating plate 33, the heat radiating plate 33 is formed with a notched portion 33a to thereby ensure insulating distances to the diode bridge 101 and the semiconductor switching element 205, and the shunt resistor 30 is arranged on a straight line the same as that between the diode bridge 101 and the semiconductor switching element 205.
