Additional Product
Information
Shelf life - important to
rotate inventory.
Application Techniques
Applications
Low stretch polyester film
for machine, as well as
hand application.
Solvent clean-up of the
board is recommended to
facilitate subsequent
soldering.
For masking printed circuit
boards during solder
stripping and precious metal
plating of fingers.
Tape must be firmly
pressed down by equipment
with rubber covered rollers
or a rubber covered platen
press. Hand rolling usually
does not provide enough
pressure. A vivid outline of
the circuit leads indicates
adequate pressure was
used.
Splicing of silicone coated
papers.
FEATURES
Polyester backing.
Thick adhesive coating.
Specially designed
adhesive.
ADVANTAGES
Reduces stretch and
recovery of tape and
associated uneven stop-off
line.
Reduces undercutting
because adhesive blocks
out solutions between
fingers.
Tape generally performs
