TEMPORARY SOLDER RESISTS
SPOT-ON, COPPER SPOT-ON
& AQUA SPOT-ON
Multicore Temporary Solder Resists are designed to be used on
printed circuit boards prior to soldering and will withstand
fluxing and wave soldering operations.
l
Peelable and water soluble versions available
l
Withstand high temperatures
l
Long shelf life

Thixotropic - holds position
Copper Spot-On
does not need to be completely dry to
withstand soldering temperatures, however it should be completely
translucent before removal is attempted.
Aqua Spot-On
should be applied at a thickness of 0.25-0.4mm
(10-15 thou). As with
Copper Spot-On,
drying times are dependent
upon ambient conditions.
Aqua Spot-On
will cure in one hour at
25°C (77°F) or 30 minutes at 80°C (176°F). If required,
Aqua Spot-
On
may be thinned before application using deionised water. Drying
times and the softness of the mask may be modified to suit ambient
conditions as follows:
(a) Very dry operating environments may benefit by adding small
amounts of glycerine to
Aqua Spot-On.
This will soften the mask
and reduce the required washing time.
(b) Extremely humid operating environments (greater than 90% RH)
will benefit by adding small amounts of isopropanol to
Aqua
Spot-On.
This will reduce the drying time and increase the
hardness of the mask.
Over curing of these products should be avoided to prevent removal
problems caused by blistering of the mask.
APPLICATIONS
Multicore Temporary Solder Resists have been formulated for use in
most commonly found forms of mask application. The three
formulations are suitable for different application and removal
techniques.
Copper Spot-On
is suitable for hand, robotic, pneumatic or
template screening application and is simply removed after soldering
by peeling off. It is particularly suited for use on copper, gold, silver or
pre-soldered surfaces.
Spot-On
is a similar product which can also be applied by brush.
It may be used on copper but some surface degradation and/or drop
in solderability may be experienced. In this case, Copper Spot-On is
recommended.
Aqua Spot-On
is a water soluble product which should be
applied by hand dispensing and removed during the cleaning
operation.

RECOMMENDED OPERATING CONDITIONS
The substrate should be free from grease, oil and particulate matter.
Spot-On
should be applied at a liquid coating thickness of
2.0mm (80 thou) to ensure a coherent film for ease of subsequent
removal as it dries to a thinner coating. It will dry in 40 minutes at
80°C (176°F) or 2 hours at ambient temperature.
For best results,
Copper Spot-On
should be applied at a
thickness of 0.5-1.0mm (20-40 thou). Drying times depend upon
ambient humidity but as a guide, under normal conditions,
Copper
Spot-On
is ready for the soldering process in one hour. This may be
accelerated to 30 minutes at 65°C (150°F) or 20 minutes at 80°C
(180°F). The mask will change from an opaque pink to a translucent
red when completely cured.
