IEC 60286-1:2021 pdf download.Packaging of components for automatic handling – Part 1: Tape packaging of components with axial leads on continuous tapes
1 Scope
This part of IEC 60286 applies to the tape packaging of components with axial leads for use in electronic equipment. In general, the tape is applied to the component leads. It covers requirements for taping techniques used with equipment for the preforming of leads, automatic handling, insertion and other operations, and includes only those dimensions which are essential to the taping of components intended for the above-mentioned purposes.

4 Dimensions
4.1 Dimensions common to tapes and taped components with axial leads 4.1.1 General The general configuration is shown in Figure 1, Table 1 and Table 2.4.2 Taping 4.2.1 General The following requirements for axial components shall be met as appropriate (see Figure 1). 4.2.2 Orientation of polarized components All polarized components shall be oriented in one direction; the polarized components shall be clearly identified by use of different colours or marked tapes, the anode being of a white or neutral colour. 4.2.3 Position, kinks and bends of the leads The position, kinks and bends of the leads are as follows. a) The leads shall be free from kinks and bends. b) The method used to position the component leads on the tape shall be such that the leads are not nicked or otherwise damaged. c) Leads shall not be bent beyond 1,0 mm (for B = 26 mm) or 1,2 mm (for B > 26 mm) from their nominal position when measured from the leading edge of the component lead at the inside tape edge and at the lead egress from the component (see dimension M in Figure 1). 4.2.4 The ends of the leads Lead protrusion The ends of the leads shall not protrude beyond the tapes. 4.2.5 Holding in the tape The components shall be held sufficiently in the tape(s) so that they cannot come free during normal handling. 4.2.6 Requirements of tape material, storage, and handling The tapes shall be suitable to withstand storage of the taped components. The tape material shall not migrate along the leads or give off vapours that can affect solderability or deteriorate the component properties or leads by chemical action (e.g. corrosion).In addition, the tapes shall not become detached, thereby causing the components to lose their relative position after storage, and the tape shall not age to such an extent that its strength is reduced, causing it to break either when the components are unreeled manually or by an assembly machine. Tapes in adjacent layers shall not stick together in the packing, because of the exposed adhesive for instance. 4.2.7 Splices of tape Splices shall be at least as strong as the original tape and shall not be thicker than four times the thickness of a single layer of the original tape. Splices shall not be misaligned by more than 0,8 mm. When splicing is applied, component spacing A shall remain within the tolerances as specified in Table 2.
