Anisotropic Conductive Film 5363
Product Description
3M™ Anisotropic Conductive Film (ACF) 5363 is a
heat-bondable, electrically conductive adhesive film.
The unbonded film is non-tacky at room temperature
and consists of a thermoset-thermoplastic adhesive
matrix randomly loaded with conductive particles. These
particles allow inter-connection of circuit lines through
the adhesive thickness, but are spaced far enough
apart for the product to be electrically insulating in the
plane of the adhesive. Application of heat and pressure
causes the adhesive to flow and to bring the circuit pads
into contact by trapping the conductive particles. The
adhesive rapidly cures at modest bonding temperature.
The 3M ACF 5363 may be used to bond a flexible printed
circuit to another flexible printed circuit or to a printed
circuit board.

For a given application, values may differ depending on particular substrate
material or type of circuitry.
Measured for gold/nickel/copper polyimide flex circuits bonded to printed
circuit board. Contact overlap area was 0.15 sq. mm. Pad pitch was 200
microns.
3M internal test method TM-2314 based on test method IPC 650 – Section
2.6.24. The flex has the shorting strap located near the bond-line to
approximate a 4-wire test structure and eliminate most extraneous
resistance in the measurement due to the circuit lines.
Results listed for minimum bonding conditions of 160°C x 5 sec. Higher
values are possible with increase in bonding temperature or time.

Assembly Process
(continued)
Bonding of 3M ACF 5363 requires a three-part procedure:
Tacking the film to one substrate (pre-tacking)
Removing the release liner
Bonding the first substrate to the second substrate.
A pre-tacking temperature of 90°C under a pressure of
about 10 kg/cm
2
should be used.
For automated ACF
application:
Set the ACF pretacking equipment to deliver
the conditions provided in the Tacking and Bonding
Conditions Table above. Slight adjustment to these
conditions may be necessary for each application or for
different types of circuitry.
For manual ACF application:
Cut the adhesive to the size of the flex circuit. Place the
adhesive on the flex and set flex on hot plate at setpoint
up to 90°C. Use roller to press adhesive onto the flex.
After allowing flex and adhesive to cool, remove liner.

Assembly Process Techniques
Assembly Process
A source of heat and pressure, such as a thermo-compression
(hot bar) bonder is required for use of 3M™ Anisotropic
Conductive Film 5363. Several commercially available
models exist: a list of vendors can be obtained by calling the
toll free number on the back of this Technical Data Sheet.

For a given application, values may differ depending on particular flex circuit
and PC board materials used.
Measured for gold/nickel/copper polyimide flex circuits bonded to gold/
nickel/copper/FR-4 PC board. Contact overlap area was 0.2 sq. mm.
Pad pitch was 200 microns.

Temperature measured in the adhesive. Thermode set points will be higher
and will depend upon the substrate materials and bond equipment.
A typical bonding set-up for a flex interconnect bond is a thermode
temperature of 300°C and a bonding time of 10 seconds (see next note).
The required minimum bonding temperature of 195°C is usually reached
within the first 5 seconds of bonding. The adhesive should be bonded so
that the temperature is held above the minimum of 195°C for at least
an additional 5 seconds. Also, it may be desirable to hold pressure while
cooling to below 100°C for maximum performance.

Assembly Process Techniques
(continued)
Final bonding must be done under heat and pressure,
with a typical desirable bond line temperature at or
above 200°C, held for 10 seconds, and a pressure of 30
kg/cm
2
. During bonding, electrical contact is typically
achieved within the first seconds after the bond line
reaches about 195°C. Additional time at temperature is
necessary to fully cure the epoxy material to generate
peel strength and the ultimate reliability. Bond times
may vary depending upon the substrates to be bonded.
For maximum mechanical and electrical performance,
the pressure should be maintained while cooling to
below 100°C. This increases the total bond time. The
time required to drop adhesive bond-line temperature
below 100°C is highly dependent upon the bonding
equipment used.
Storage
3M™ Anisotropic Conductive Film 5363 should be kept
frozen in the original airtight shipping bag. 3M ACF 5363
has a shelf life of 15 months from date of manufacture
when stored at temperature ≤ 2°C. The product should be
allowed to warm to room temperature for approximately
30 minutes prior to use to prevent moisture condensation
on the film. Whenever possible, 3M ACF 5363 should be
kept away from high humidity environments as absorbed
water can lead to moisture volatilization producing
bubbles during heat bonding or gradual degradation
of the product. The 3M ACF 5363 can be held at
room temperature for product utilization provided the
cumulative room temperature shelf life is not exceeded.
The room temperature shelf life is 4 weeks.
