ESD Determination Methods for INT 702

INTERTRONICS INT 702 Anti
Static Polyimide Masking Tape is tested for the generation of static
charges.

1) ESD During Roll Unwind

Procedure
A roll of INT 702 (25.4mm wide and
0.025mm film thickness) is mounted in a standard tape dispenser. The free
end of the roll is held in a hand and the roll is unwound manually. The
minimum unwind speed is 300mm/s. Using a 3M 703 static meter, the
resulting static charge (if any) is measured.

Conditions
Temperature: 23°C +/- 2°C
Relative
humidity: 50% +/- 2%
Distance from static meter: 50mm

Result
Maximum 5 Volts
2) ESD During
Removal from a Stainless Steel Plate

Procedure
A section of INT 702 (25.4mm x 300mm) is
applied to a clean stainless steel plate. The free end of the tape is then
held and manually the tape is removed from the plate at a minimum speed of
300mm/s and at angles of between 90° and 180°. The resulting static charge
(if any) on the plate is measured.

Conditions
Temperature: 23°C +/- 2°C
Relative
humidity: 50% +/- 2%
Distance from static meter: 50mm

Result
Maximum 5 Volts
3) ESD During
Removal from Gold Fingers of a PCB

Procedure
applied to the gold fingers of a printed circuit board (pcb). The free end
of the tape is then held and manually the tape is removed from the plate
at a minimum speed of 300mm/s and at angles of between 90° and 180°. The
resulting static charge (if any) on the plate is measured.

Conditions
Temperature: 23°C +/- 2°C
Relative
humidity: 50% +/- 2%
Distance from static meter: 50mm

Result
Maximum 5 Volts
4) ESD During
Removal from Centre of a PCB

Procedure
applied to the centre area of a pcb. The free end of the tape is then held
and manually the tape is removed from the plate at a minimum speed of
300mm/s and at angles of between 90° and 180°. The resulting static charge
(if any) on the plate is measured.

Conditions
Temperature: 23°C +/- 2°C
Relative
humidity: 50% +/- 2%
Distance from static meter: 50mm

Result
Maximum 5 Volts
