Abstract:
A contact tail for an electronic component compatible with surface mount manufacturing techniques. The contact tail is stamped, providing a relatively low manufacturing cost and high precision. High precision in the contact tails in turn provides more reliable solder joints across an array of contact tails in an electronic component. Further, the contact tail may be shaped to reduce the propensity for solder to wick from the attachment area during a reflow operation. Reducing the propensity of solder to wick reduces the chance that solder will interfere with the operation of the electronic component. Additionally, reducing the propensity for solder to wick allows pads to which the contact tail is attached to be positioned over vias, thereby increasing the density with which contacts may be attached to a substrate. The reliability with which electronic assemblies incorporating components using the contact tail is also increased when the contact tail is used in self-centering arrays.
Abstract:
A surface mounting discharge tube, comprise of a cylindrical ceramic envelope sealed at its two ends by side surfaces of electrodes, designed to be directly soldered on to a mounting board, where the electrodes at the two ends are rectangular, project outward radially at the ends of the ceramic envelope and are provided at peripheral edges at the side surfaces of the electrodes with soldering use tapers or step differences, whereby positional deviation at the time of soldering is suppressed and sufficient PCT properties are secured.

수지 몰드로 덮인 소자 및 수지 몰드로부터 돌출한 금속 리드를 갖는 반도체 장치로서, 리드 팁 부는 땜납 도금에 의해 전부 덮이고, 땜납 도금에 의해 덮이지 않는 리드 팁 단부면은 금속 리드의 단면적의 절반보다 작은 면적을 가짐으로써, 금속 리드의 땜납 젖음성이 개선되고 회로 기판에 대한 접합 강도 또한 개선된다. 반도체 장치, 리드 프레임, 금속 리드, 수지 몰드, 리드 팁 부, 땜납 도금
Abstract:
전극의 측면에 의해 양단부가 밀폐되고, 실장 기판 상에 직접 접합되도록 설계된 원통형의 세라믹 엔빌로프(envelope)를 포함하는 표면 실장용 방전관에 있어서, 상기 양단부의 전극은 사각형이고 세라믹 엔빌로프의 단부로부터 외측으로 방사상으로 돌출되어 있으며, 이 전극의 측면의 가장자리에 땜납 접합용의 테이퍼(taper) 또는 단차(段差)를 구비함으로써, 땜납 접합시의 위치 변위를 억제하고 충분한 PCT 특성을 확보한다. 실장 기판, 테이퍼, 단차, 땜납, 방전관
Abstract:
Die Erfindung betrifft eine Verbindungsanordnung (100) zwischen einem Anschlusssteckerkörper (1) und einem Schaltungsträger (5) in einem elektrischen Gerät, mit mehreren, insbesondere parallel zueinander angeordneten Steckeranschlusselementen (10; 10b; 10c; 10d; 10e), die im Wesentlichen geradlinig ausgebildete Endabschnitte (11; 11e) aufweisen, die dazu ausgebildet sind, in jeweils eine Aufnahmeöffnung (6) des Schaltungsträgers (5) unter Ausbildung einer elektrisch leitenden Verbindung eingeführt zu werden. Erfindungsgemäß ist es vorgesehen, dass mit den Endabschnitten (11; 11e) in Kontakt stehende Führungsmittel (20) zum Ausrichten der Endabschnitte (11; 11e) in die Aufnahmeöffnungen (6) vorgesehen sind.
