IEC 61188-7:2017
IEC 61188-7:2017 establishes a consistent technique for the description of electronic component orientation, and their land pattern geometries. This facilitates and encourages a common data capture and transfer methodology amongst and between global trading partners.
This edition includes the following significant technical changes with respect to the previous edition:
a) Figure 1 has been corrected;
b) the term “rectangle” has generally been replaced by “polygon”;
c) level B has been indicated as preferred level for new libraries.
