The assumption is that the following dimensions have the necessary and sufficient accuracy: a) component tolerance; c) printed board fabrication tolerance; d) placement tolerance. NOTE Further information on the effect of the above dimensional tolerance on the land pattern can be found in Annex A of IEC 61188-6-1:2021. There are two classes of land pattern relating to the assembly limitations of components and the intended soldering process: • land pattern for wave soldering – For low density product applications, land patterns are designed to accommodate several types of wave soldering applicable to surface mounted components. • land pattern for reflow...11-29

1 Scope This part of IEC 60794 specifies a method of verifying that cable metallic elements are electrically continuous throughout the cable. Electrical continuity is important for bonding and grounding, toning for location, and other related system issues, and may represent a “goodness of manufacture” criterion. Typically, the test is one of continuity and carries no resistance or conductivity requirement. The metallic elements can be tested individually or can be tested as a total group. Since this latter criterion is frequently the case, all elements are measured as a group unless specified otherwise. NOTE It is possible detail specifications allow...11-29
