EN 60286-1-2017 pdf download.Packaging of components for automatic handling – Part 1: Tape packaging of components with axial leads on continuous tapes (IEC 60286-1:2017).
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.
4.2.3 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 1,0mm (for B = 26mm) or 1,2mm (for B >26mm) 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
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 .1 shall remain within the tolerances as specified in Table 2.
4.2.8 Leader tape
5.3 Distances U1 and
The distances and 112 shall be governed by the overall width of the taped components li
(see Figure 1) and shall allow proper reeling and unreeling.
5.4 Recycling
Reels as defined in Figure 2 should be made of recyclable material. When such material is used, the reel shall be permanently marked with the recycling symbol.
ISO 11469 should be used for making the material.
5.5 Protection of components
In order to prevent component damage and lead distortion, protection between layers of components and over the last layer may be necessary. In this case, protection materials shall not cause deterioration of the component or of lead solderability.
5.6 Reel filling
The total number of components on the reel shall be such that the components and the final cover shall not extend beyond the smallest dimension of the flange in the radial direction.EN 60286-1-2017 pdf download.
