Mechanical standardization of semiconductor devices - Part 1: General rules for the preparation of outline drawings of discrete devices

Edition date: 2018-01-23
In Force
Available languages: English, French
Summary: IEC 60191-1:2018 gives guidelines on the preparation of outline drawings of discrete devices, including discrete surface-mounted semiconductor devices with lead count less than 8.
This edition includes the following significant technical changes with respect to the previous edition:
a) the Scope has been extended to include surface-mounted semiconductor devices with a lead count less than 8;
b) a definition of the term "stand-off" has been added;
c) the methods for locating the datum have been extended to be suitable for SMD-packages;
d) the visual identification of terminal position one for automatic handling has been clarified;
e) the rules for the drawing of terminals have been clarified;
f) Table A.1 has been completed with symbols specifically for SMD-packages;
g) Annex B "Standardization philosophy" has been deleted;
h) a normative Annex with special rules for SMD-packages has been added;
i) the examples of semiconductor device drawings have been aligned to state-of-the-art packages including SMD-packages.

L’IEC 60191-1:2018 donne des lignes directrices pour la préparation des dessins d’encombrement des dispositifs discrets, comprenant les dispositifs discrets à semiconducteurs pour montage en surface dont le nombre de connexions est inférieur à 8.
Il convient également de se référer à l’IEC 60191-6 pour la préparation des dessins d’encombrement des dispositifs discrets pour montage en surface dont le nombre de connexions est supérieur ou égal à 8.
L’objectif principal de ces dessins consiste à indiquer l’espace à octroyer aux dispositifs dans un équipement, ainsi que d’autres caractéristiques dimensionnelles exigées pour assurer une interchangeabilité mécanique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
  1. le domaine d’application a été étendu pour couvrir les dispositifs à semiconducteurs pour montage en surface dont le nombre de connexions est inférieur à 8;
  2. une définition du terme "élévation" a été ajoutée;
  3. les méthodes de positionnement de la référence spécifiée ont été étendues pour englober les boîtiers des composants pour montage en surface (CMS);
  4. l’identification visuelle de la position de broche no 1, dans le cadre des procédures de manipulation automatique, a été clarifiée;
  5. les règles de représentation des broches ont été clarifiées;
  6. le Tableau A.1 a été complété avec des symboles spécifiquement destinés aux boîtiers CMS;
  7. l’Annexe B "Concept de normalisation" a été supprimée;
  8. une annexe normative avec des règles spécifiques aux boîtiers CMS a été ajoutée;
  9. les exemples de dessins de dispositifs à semiconducteurs ont été alignés sur l’état de l’art des boîtiers, en englobant les boîtiers CMS.
