Newly developed trays which follow these rules will not be listed individually. Only those trays which conform to the design
13、rules set forth herein are classified as “standard trays“ and are thus preferred for use. b) An update of the matrix trays, which do not conform to the design rules set forth herein, are considered as “non-standard trays“ and are not preferred for use, is listed in Annex A.

25、s 1 Scope This part of IEC 60286 describes the common dimensions, tolerances and characteristics of the tray. It includes only those dimensions which 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
26、 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 standard Newly developed trays which follow these rules will not be listed indivi
27、dually . Only those trays which conform to the design rules set forth herein are classified as “standard trays” and are thus preferred for use. NOTE Matrix trays listed in Annex A which do not conform to the design rules set forth herein shall be considered as “non-standard trays” and are not prefer
28、red for use. 2 Material 2.1 Electrostatic dissipative requirements 2.2 Effect of properties The tray material shall not adversely affect the mechanical, electrical characteristics, solder- ability, or marking of the component during or after transport, baking or storage in the tray. 2.3 Recycling an
29、d rigidity The tray material shall be reusable or recyclable and shall be rigid enough to avoid damage to the components during handling, loading, baking, testing, shipping and placement operations. There should be space for a recycle logo and material code or material declaration close to Detail B.
30、 3 Mechanical stability 3.1 Loaded tray Mechanical stability of loaded trays shall be such that the components are adequately retained, without lead damage, and can be easily removed from the tray. 3.2 Empty tray The empty tray shall withstand normal environmental conditions (including component bak
31、ing temperatures, if required) without distorting, warping, expanding, shrinking or any other physical change outside the specified dimensions of the trays. Trays shall be moulded from material that meets the ESD dissipative requirements surface resistance equal to or greater than 1,0 10 5ohms/squar

34、ackage is oriented parallel to the length of the tray to maximize tray pocket density. 4.1.3 Design rules for pocket density 4.1.3.1 Formulas NOTE After the maximum matrix has been established by the above calculation using a minimum W value, N1 and N2 may not have resulted in even numbers and may t
35、herefore have been rounded down to the nearest whole number.
