Applications for Conductive Shielding Grid Tape

• For applications requiring EMI shielding

• Use in areas where the generation of static electricity is of

concern

• Using grounded Tape Dispenser, voltage generated

by unrolling will effectively be reduced to approaching

zero

• Secure (bundle) IC tubes

• Cover external plugs, holes or connector pins on electronic

chassis (black boxes, etc.) during transporta tion or storage

Excerpt from the Naval Aviation Schools Command: “..

Weapon Replaceable Assemblies (WRA)s shall have ESD

conductive plug caps or grid tape over all external cannon

plugs and connector pins.”

Normal use of our High Temperature Masking Tape is for

masking or protective applications on printed circuit boards

not exceeding temperatures of 150°C (302°F) at a duration

under 45 minutes. If the tape is used for masking operations

or temporary protection, it should not be left on the product

for more than 24 hours. For best results, the tape should

not be exposed to ultraviolet rays or high temperature for

prolonged periods of time (beyond manufacturer’s specs).

This tape is non-staining under normal use as described

above.

Applications for High-Temp Masking Tape

• Silk screening applications

• Masking application in spray and brush painting,

non-staining

• Protective purposes in manufac turing processes, strips

clean

• For securing polyethylene sheeting to walls during painting

• For OEM repair shops

• Use in applications masking PCBs gold features for wave

soldering or soldering under 302°F (150°C)

• For best results, apply to board using a rubber roller.

• Thick conductive adhesive excellent for conformability to

protect critical PCB features

• Easily handles high temperatures of wave soldering

without leaving significant residue

• Handles temperatures found in test and burn-in ovens

Tape Dispenser

2 inch wide ESD Tape Dispenser

• Use with Wescorp ESD tapes

• For tape with 3" (7.62 cm) Cores

• For tapes rolls up to 2" (48 mm) wide (or combination of

rolls)

• Groundable chassis with included ground cord

Wescorp Tape Storage:

For best results, tape inventory should be continually

replenished. It is recommended that rolls of tape be stored

flat and rotated (flipped over to the other side) periodically.

Tapes should be stored in a dry, well ventilated room with

a reasonably consistent temperature of 68°F (20°C) and be

protected from exposure to direct sunlight. Tape should not

be stored in ultraviolet sunlight, moisture, or heat. Tape over

one year old should be evaluated by the user to determine

acceptability for the user’s application.
