PACKAGING OF COMPONENTS FOR AUTOMATIC HANDLING –
Part 5: Matrix trays
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60286-5 has been prepared by IEC technical committee 40:
Capacitors and resistors for electronic equipment.
This second edition cancels and replaces the first edition published in 1995 and constitutes a
technical revision.
This edition includes the following significant technical changes from the previous edition.
a) The generic rules for the design of matrix trays are given in this standard. Newly
developed trays which follow these rules will not be listed individually. Only those trays
which conform to the design 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.

PACKAGING OF COMPONENTS FOR AUTOMATIC HANDLING –
Part 5: Matrix trays
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 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 individually . 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 preferred for use.
2 Material
2.1 Electrostatic dissipative requirements
Trays shall be moulded from material that meets the ESD dissipative requirements which are:
5 12
equal to, or greater than, 1,0 × 10 ohms/square but less than 1,0 × 10 ohms/square.
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 and 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’.
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 baking
temperatures, if required) without distorting, warping, expanding, shrinking or any other
physical change outside the specified dimensions of the trays.
---------------------- Page: 9 ----------------------
60286-5 IEC:2003(E) – 7 –
3.3 Outer edges
The outer edges of the tray shall be of sufficient thickness and strength to allow mechanical
positioning and clamping.
4 Tray design, dimensions and other physical properties
4.1 Tray design
4.1.1 Number of pockets
All new tray proposals should maximize the number of pockets in each tray-family variation
without violating the pocket-density design rules specified in 4.1.3.
4.1.2 Orientation of pockets
When designing a tray for a rectangular package, the longest dimension (D) of the package 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
DT is D + strengthening pocket rib width W
max
ET is E ” + strengthening pocket rib width W
max
M is (135,9 mm – M3(N1 – 1))/2
M1 is (315,0 mm – M2(N2 – 1))/2
M2 is [(315,0 mm – 6,4 mm) – W(N2 – 1)]/N2 + W
M3 is [(135,9 mm – 6,4 mm) – W(N1 – 1)]/N1 + W
N1 is (135,9 mm − 6,4 mm)/ET (rounded down to a whole number)
N2 is (315,0 mm − 6,4 mm)/DT (rounded down to a whole number)
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 therefore have been rounded down to the nearest whole
number. This means we may have fractions of millimetres extra that should be added back to M2 and M3 to
maximize the pitch between the pockets while minimizing the edge of the tray to the centre line of the first pocket
M and M1.
4.1.3.2 Constituents of the design rules, formulas and drawings
D is determined by appropriate specification
max
DT is the max. length D + strengthening pocket rib width W
E is determined by appropriate specification
max
ET is the max. width E + strengthening pocket rib width W
M is the edge of the tray width to the centre line of the first pocket
M1 is the edge of the tray length to the centre line of the first pocket
M2 is the pitch of the tray pocket in the tray length
M3 is the pitch of the tray pocket in the tray width
N is the package lead counts supported
N1 is the number of columns in the tray
N2 is the number of rows in the tray
N3 is the total number of pockets in the tray (N1 × N2 = N3)
---------------------- Page: 10 ----------------------
– 8 – 60286-5 IEC:2003(E)
N4 is the package type accommodated
N5 is the end vacuum pick-up area(s)
N6 is the centre vacuum pick-up area(s)
W is the strengthening pocket rib width
NOTE The tray sponsor will determine W from the latest manufacturing capabilities and design feature needs at
the time of the new tray-family design.
W should not exceed the target value of 2,00 mm in order to achieve the maximum tray
density unless required by application.
4.2 Overall tray dimensions
Overall tray dimensions shall be 322,6 mm in length and 135,9 mm in width. Overall height A,
stacking step height A1 and edge height A2 are given in Table 1.

Notes related to Figures 3 and 4
These surfaces should be free of seams.
1
Chamfer denotes package pin 1 orientation.
2
The tray vacuum pick-up method requires two separate pick-up areas represented by bottom closed cells. Optional
3
vacuum pick-up cell locations are N5.
The tray vacuum pick-up method requires a minimum walled pick-up area of 28 mm × 28 mm, located as close to
4
the centre of the tray as is practical. Centre vacuum pick-up cell locations are N6.
This scallop is centred on the side of the tray and allows the use of a pin to bias mechanically the tray orientation.
5
6 The symbol N refers to package lead count supported, where applicable.
Total usable cells N3 = N1 × N2 (columns × rows). Columns run top to bottom along the length of the tray. Rows
7
run left to right across the width of the tray.
Dimensions M, M1, M2 and M3 define the centre lines for the cell sites. Package interface is controlled by package
8
design and lead form.
9 Non-tabulated dimensions have a tolerance of
X = ± 0,25;
XX = ± 0,13; angles = ± 0,5°.
10 Dimensions are in millimetres.
11 Interpret dimensioning and tolerancing in accordance with ANSI Y14.5M-1982.
XXX °C is the maximum temperature to which the empty tray can be subjected to for 48 continuous hours without
12
violating the dimensional tolerance of the tray.
N4 indicates the package type accommodated.
13
Bottom side-wall notches require a minimum depth of 2 mm to facilitate auto handling equipment.
14
All tray measurements are to be made with the tray unrestrained.
15
Sharp edges that could cause damage to dry-pack bags or other packaging material should be avoided regardless
16
of whether or not an edge or corner radius is specified.
17 There should be space for a recycle logo and material code or material declaration close to Detail B.

5 Polarity and orientation of components in the tray
5.1 Pin one
Pin 1 of the component shall be orientated towards the tray chamfer corner or the side of the
tray with the centre scallop.
5.2 Loading
Components shall be loaded into the tray starting at the lower right corner diagonally opposite
the chamfered corner of the tray. Proceeding from bottom to top and right to left, the columns
shall be completely filled from bottom to top before placing a component in the next column.
6 Tray stacking
6.1 Bundling
Trays may be bundled in stacks providing the stacks contain only components of the same
part number and the same manufacturer.
6.2 Top protection
The top tray containing components shall be protected by an empty tray or a suitable
equivalent lid.
6.3 Partial filling
A stack of trays shall not contain more than one partially filled tray. Except for the protective
cover tray (lid), any partially filled tray shall be the top tray of the stack as received from the
supplier.
6.4 Protrusion of components
The component shall not protrude above the top surface profile of the tray. A heat-sink,
attached to the top of a component, may protrude above the top surface of the tray. When
such a heat-sink is used, suitable "spacer" trays shall be used in the stack.
6.5 Stack-up
Trays shall be stackable without interference and shall not stick together during unstacking
operations.
6.6 Damaging of components
Trays shall be stackable without damaging contained components.
7 Missing components
Missing components are not allowed, except for an intentionally partially filled tray as
described in 6.3.
---------------------- Page: 17 ----------------------
60286-5 IEC:2003(E) – 15 –
8 Marking
The tray shall be marked with the following.
a) The type of component the tray is intended to obtain.
b) The temperature in degrees Celsius, which the empty tray will withstand for 48 conti-
nuous hours, without violating the dimensional tolerance of the tray.
c) When required, a label with information in normal script or in code form, for example,
OCR bar code, magnetic, etc., for automatic reading shall be placed on the right side of
the tray (opposite side from scallop).
• In the case of bar codes, it is recommended to use bar code 39.
• For optical character recognition, OCR B should be used.
