This part of IEC 60286 describes the common dimensions, tolerances and characteristics of
the tray. It includes only those dimensions that are essential for the handling of the trays for
the stated purpose and for placing or removing components from the trays.
Matrix trays are designed to facilitate the transport and handling of electronic components
during their testing, baking, transport/storage, and final mounting by automatic placement
equipment.
The generic rules for their design are given in this document. Newly developed trays that
follow these rules will not be listed individually. Only those trays that conform to the design
rules set forth herein are classified as "standard trays" and are thus preferred for use.
