3MTM Non-Conductive Polycarbonate
Carrier 2703
Product Description
Product Format
3M Non-Conductive Polycarbonate Carrier 2703, used in
conjunction with a suitable 3M cover tape, serves as a reliable
and convenient means of helping protect and transport
electrical and electronic devices, and precisely delivering
them to the assembly point. 3M Polycarbonate Carrier 2703
is a continuous, splice free, non-conductive carrier tape with
precisely formed pockets to ensure component fit to ANSI/EIA
guidelines. Polycarbonate Carrier 2703 is available in a broad
selection of pocket designs with dimensions to accommodate a
variety of common electrical and electronic parts. Customized
Polycarbonate Carrier 2703, with dimensions specific to your
requirements, is also available upon request.
Polycarbonate Carrier 2703 is available as continuous, splice-free,
8mm–120mm carrier on recyclable 560mm diameter cardboard
supply reels in planetary format. Most 8mm–24mm carriers are also
available in a level wound format utilizing up to a 7'' wide core. Reel
capacity will typically be from 500 to 1,000 meters, depending upon
the pocket depth, pitch and winding format.
Construction
Embossed, non-conductive, heat-resistant, polycarbonate film.
Dimensional Properties
Polycarbonate Carrier 2703 meets the ANSI/EIA-481-D Standard
for the dimensions illustrated below.
Note:The technical information and data presented here should be considered
representative or typical only, and should not be used for specification purposes.
Typical Mechanical Properties–Shrinkage
Note:The technical information and data presented here should be considered
representative or typical only, and should not be used for specification purposes.
02
Unlike many polyvinyl chloride and polystyrene carrier tapes,
which typically shrink in excess of 0.5% after 24 hours of
exposure to 60oC (140oF), 3M™ Non-Conductive Polycarbonate
Carrier 2703 exhibits shrinkage of less than 0.1%, even after 24
hours exposure at 85oC (185oF). This compares favorably to the
EIA-481-D standard which stipulates that the P0-10, or ten-pitch
tolerance, maintain a dimension of 40.0mm ± 0.2mm, an implied
tolerance of ± 0.5%. Carrier shrinkage can result in problems
with feeding, pocket position, and in the case of the pocket
dimensions, parts sticking in the pockets. The extent of shrinkage
in cold-formed polyvinyl chloride or polystyrene carrier pockets
can be rapidly accelerated by exposure to elevated temperature,
and will depend upon the duration of exposure and the maximum
temperature reached. Exposure of many of these other carriers to
as little as 24 hours at 50oC (122oF) can cause shrinkage in such
carriers to exceed the implied EIA-481-D dimensional tolerance.

Test Notes
1. Engineering grade resin.
2. Tensile tests are conducted at 21°C (70°F), 50% RH under controlled conditions with a constant rate of jaw
separation of 100mm/minute from an initial separation of 126mm. Yield strength is the force which produces 5%
elongation of the sample. Breaking strength is the ultimate strength for the material at the break point.
3. Impact strength testing utilizes a mandrel to hold a section of the material under test. A weight is allowed to
strike the material from a known radius and after the strike the swing is measured vs free swing and the strength
of the material is calculated from the difference.
4. Shrink is measured at 60°C (140°F)/85% RH as well as the 85°C (185°F) after 24 hours exposure and
expressed in percentage of the initial measurement.
5. Camber is a measurement of the weave of the material. Measured over a 250mm length.
6. Optical properties are measured using a BYK-Gardner Haze-Gard Plus Transmission Meter, Model 4725.
7. Resistivity tests are conducted at 21°C (70°F), 50% RH under controlled conditions. Resistivity is measured at
the sealing surface of a typical carrier using the defined test method.
8. Chemical extraction is measured using 20-hour water extraction test as defined in the test method MIL STD
883E, test method 5011. Resultant solutions are measured using chromatography.

Product Description
3M Conductive Polycarbonate Precision Carrier 3000BD for bare die
applications is designed to meet the demanding needs of many bare
die, flip chip and micro BGA applications traditionally served by trays
or other carrier devices. 3M innovation has led to the development of
precision pockets, a technical breakthrough allowing 3M to produce
highly precise and accurate pockets conforming to and helping
protect your chip. Compare 3M Polycarbonate Carrier 3000BD to a
typical, traditional heat-formed pocket:
Precision Polycarbonate Pocket
for cleanroom applications. For non-cleanroom applications,
Polycarbonate Carrier 3000BD is available in planetary or level-wind
format on a recyclable 560mm (22") cardboard reel. Reel capacity
will typically be from 30 to 1,000 meters, depending upon pocket
depth, pitch and winding format.
Component Protection is Critical
3M precision capabilities allow for innovative ways to help protect
your chips from corner damage. Polycarbonate Carrier 3000BD
corner protection helps prevent die edge chipping, one of the most
common problems when shipping die products.*

The eect of contaminants on the solderability of SnPb, InPb, Au or
Cu solder bumps is a concern to many manufacturers of flip chips.
Polycarbonate Carrier 3000BD contains a minimum of identified
corrosive, water-extractable ionic contaminants which are present in
more significant levels in some other typical carriers. The following
chart compares some typical carriers tested according to the
requirements of MIL-STD-883E, Method 5011.
Electrical Properties
Storage Conditions
The electrical and triboelectric properties of 3M ™ Polycarbonate
Carrier 3000BD have been engineered to help provide protection
of static-sensitive chip-size packages through an eective balance
between the electrostatic shielding and electrostatic decay properties
of the carrier. Polycarbonate Carrier 3000BD is electrically conductive,
exhibiting a nominal surface resistivity in the pocket of≥10 4Ω /
square and≤10 8Ω /square. Polycarbonate Carrier 3000BD also
exhibits desirable triboelectric properties which may be appropriate for
packaging electrostatically-sensitive chip-size packages.
It is recommended that Polycarbonate Carrier 3000BD be stored
indoors, in its original packaging, in a controlled climate environment,
typically at or below 35 oC (95 oF) and 70% relative humidity.
Conditions should not exceed 85oC (185oF) for prolonged periods,
and the product must be protected from exposure to direct sunlight.
Exposure to elevated humidity reduces the compressive strength of
corrugated, cardboard containers. The recommended stacking height
must be followed to avoid damaging the packaged product. It is
recommended that the product be used on a “first-in, first-out” basis.
Packaging Format
Shelf Life
Polycarbonate Carrier 3000BD is available in a cleaned and
cleanroom compatible format for maximum protection from particle
contamination. Polycarbonate Carrier 3000BD is cleaned and
packaged in a class 10,000 cleanroom environment. Each planetary
wound 13" plastic reel is then sealed individually into a 3M™ Static
Shielding Bag for protection.
Note: Polycarbonate Carrier 3000BD is also available in standard 22" cardboard planetary and level-wind
reels for less sensitive components and non-cleanroom applications.
Recyclability
Polycarbonate Carrier 3000BD is a carbon-filled thermoplastic
polymer film which can be recycled after use.
It is recommended that Polycarbonate Carrier 3000BD be used within
five years from the date of manufacture when stored according to the
recommended storage conditions.
Cover Tape Recommendations
Bare die, flip chip and microBGA components require extreme
care during the de-taping process to prevent the components from
bouncing out of the carrier. Therefore, 3M ™ Pressure Sensitive
Adhesive Cover Tape 2666 is recommended. For packaging
components in 8mm and 12mm wide carrier tape, using 3M™

Test Notes
1. Engineering grade resin.
2. Tensile tests are conducted at 21°C (70°F), 50% RH under controlled conditions with a constant rate of
jaw separation of 100mm/minute from an initial separation of 126mm. Yield strength is the force which
produces 5% elongation of the sample. Breaking strength is the ultimate strength for the material at the
break point.
3. Impact strength testing utilizes a mandrel to hold a section of the material under test. A weight is
allowed to strike the material from a known radius and after the strike the swing is measured vs. free
swing and the strength of the material is calculated from the difference.
4. Shrink is measured at 60°C (140°F)/85% RH as well as the 85°C (185°F) after 24 hours exposure and
expressed in percentage of the initial measurement.
5. Camber is a measurement of the weave of the material. Measured in 100 mm sections over a 250mm
length.
6. Optical properties are measured using a spectrophotometer and measuring wavelengths from 450 to
800 mm. Material is considered opaque if light transmission is less than 1%.
7. Resistivity tests are conducted at 21°C (70°F), 50% RH under controlled conditions. Resistivity is
measured in the bottom of the pocket of a typical SOIC carrier using the defined test method.
Specification tolerances for this carrier is 104 ≤ Rs ≤ 108. Static decay is measured with an Electrotech
Systems Static Decay Meter Model 406-C, using the manufacturer’s suggested calibration and test
methods.
8. Chemical extraction is measured using 20-hour water extraction test as defined in the test method MIL
STD 883E, test method 5011. Resultant solutions are measured for anion analysis using
chromatography. Levels below 5.0 ppm are not reported.

3MTM Polycarbonate
Ultra Precision Carrier 3000UP & 3000UB
Product Description
Pocket Features
3M Polycarbonate Ultra Precision Carrier 3000UP and 3000UB
(for cleanroom application) are designed to meet the demanding
needs of smaller chip scale devices with dramatically reduced size
and thickness, which requires ultra-precise pockets to protect. 3M
innovation technology has ability to produce highly precise pockets
with tighter pocket dimensional tolerance and small pocket hole to
reliably transport and handle your chip.
3M Ultra Precision Carrier 3000UP and 3000UB have the capability
to provide tighter pocket dimensional tolerance for Ao, Bo, Ko
dimensions and small sidewall draft angle, which allows better chip
fit and location in pocket, with the benefit of reducing component
migration and flipping. The ultra small pocket hole (diameter down to
0.2mm) and flat pocket bottom will effectively help to prevent small
chip tilting and rotation during die taping process.
3000UP Carrier for 0603 (0201) Package
Chemical Analysis of Extractable
Contaminants
The effect of contaminants on the solderability of SnPb, InPb, Au or
Cu solder bumps is a concern to many manufacturers of flip chips.
3M Polycarbonate Ultra Precision Carrier contains a minimum of
identified corrosive, water-extractable ionic contaminants which are
present in more significant levels in some other typical carriers.
Electrical Properties
Product Format
3M Ultra Precision Carrier 3000UB is available as a splice-free,
8mm-44mm carrier in planetary format on 330mm (13") plastics
reel for cleanroom applications. For non-cleanroom applications, 3M
Ultra Precision Carrier 3000UP is available in planetary or level-wind
format on a recyclable 560 add space before mm (22") cardboard
reel. Reel capacity will typically be from 30 to 1,000 meters,
depending upon pocket depth, pitch and winding format.
10
The electrical and triboelectric properties of 3M Polycarbonate Ultra
Precision Carrier have been engineered to help provide protection of
static-sensitive components through an effective balance between
the electrostatic shielding and electrostatic decay properties of the
carrier. 3M Ultra Precision Carrier exhibit a nominal surface resistivity
in the pocket of ≥104 Ω/square and ≤108 Ω/square, and also exhibit
desirable triboelectric properties which may be appropriate for
packaging electrostatically-sensitive components.
Storage Conditions
It is recommended that 3M Ultra Precision Carrier be stored indoors,
in its original packaging, in a controlled climate environment, typically
at or below 35oC (95oF) and 70% relative humidity. Conditions should
not exceed 85oC (185oF) for prolonged periods, and the product must
be protected from exposure to direct sunlight. Exposure o elevated
humidity reduces the compressive strength of corrugated, cardboard
containers. The recommended stacking height must be followed to
avoid damaging the packaged product. It is recommended that the
product be used on a “first-in, first-out” basis.
Shelf Life
It is recommended that 3M™ Ultra Precision Carrier be used within
five years from the date of manufacture when stored according to
the recommended storage conditions.
Packaging Format
3M Ultra Precision Carrier 3000UB is available in a cleaned and
cleanroom compatible format for maximum protection from particle
contamination. Polycarbonate Carrier 3000UB is cleaned and
packaged in a class 10,000 cleanroom environment. Each planetary
wound 13" plastic reel is then sealed individually into a 3M™ Static
Shielding Bag for protection.
Camber
3M Ultra Precision Carrier in a planetary format meets the EIA481-D Standard for camber: not greater than 1mm in 250 lineal
millimeters. For the smaller chip device package, it is recommended
that planetary format be used for better component fit during taping
process.
Recyclability
3M Ultra Precision Carrier is carbon-filled thermoplastic polymer film
which can be recycled after use.
Cover Tape Recommendations
Smaller chip devices require extreme care during the de-taping
process to prevent the components from bouncing out of the carrier.
Therefore, 3M ™ Pressure Sensitive Adhesive Cover Tape 2668
and 2666 are recommended for use. 3M PSA cover tapes provide
a consistent peel force, which is ideal for many thin and small
component applications.
3M Ultra Precision Carrier 3000UP is available in standard
22" cardboard planetary and level-wind reels for less sensitive
components and non-cleanroom applications.

3M™ Universal Cover Tape (UCT) 2688A,
Static Dissipative
Product Description
3M™ Universal Cover Tape (UCT) 2688A is a transparent,
static dissipative, film tape with a synthetic, room temperature,
pressure sensitive adhesive zone. 3M UCT 2688A is specifically
designed to seal electrical and electronic components into all
embossed carrier tape materials, including paper.
Construction
Backing
Transparent Film
Adhesive
Pressure Sensitive, Synthetic Polymer
Available Widths
Universal Cover Tape 2688A is available in the standard widths listed
below, supplied in 300 meter, splice free rolls.
3M UCT 2688A has a simple process window. Desirable
adhesion to the carrier can be achieved through the application
of pressure to the non-adhesive surface of the cover tape over
the adhesive strips with a reciprocating pressure sensitive
adhesive O-ring shoe, compliant roller, or mechanical mechanism
for proper wet-out. The removal (peel) force is obtained by
peel initiation and removal of medial section of cover tape.
Still photos demonstrating typical peel initiation and removal
force procedures are shown in this tech sheet. Visit www.3m.
com/electronics for full video viewing of these demonstrations.
Removal force charts depict typical room temperature and aging
characteristics of Universal Cover Tape 2688A sealed to 3M™
Polycarbonate Carrier.

Graph Notes:
The graphs in this document represent sealing and removal
performance attained under the conditions specifically stated in
the sealing parameters section below. Pressure is the indicated
gauge pressure used to achieve seals, and may vary among
sealing equipment manufacturers. The use of a different sealing
mechanism (i.e. reciprocating versus roller or metal) may have
an effect on the performance obtained under otherwise identical
conditions due to differences in pressure or pressure distribution.
The use of heat is specifically not recommended.
Removal force “peel” data presented is representative of peel
studies conducted according to the requirements of the current
ANSI/EIA-481-D Standard. Sealed samples used in these studies
were wound on 330 mm diameter reels to simulate typical
