Warton
manufacture a range of cored solder pastes which work with
lead free alloys.
Microprint
P2006 No Clean Solder Paste
The
unique No Clean flux vehicle of Microprint P2006 offers
excellent soldering of lead free alloys. P2006 is designed
for use with a variety of substrate materials including
Sn/Pb, Au/Ni and OSP treated finishes. The solder paste
is available with formulations to offer print speeds ranging
from 20 to 300mm per second, with a Pin Testable formulation
available, allowing easy penetration of test probes through
the post soldering residues. Microprint P2006 is suitable
for use with air and nitrogen reflow systems.

Microprint
P2006 eliminates solder balling and mid-chip balling. One
of the main difficulties with conventional gel systems is
temperature instability or de-structuring of the gel matrix,
this is evident not only in manufacturing of solder paste
but during the reflowing of assemblies. If the gel matrix
de-structures before sufficient solvent is volatilized,
a washing effect takes place displacing solder particles
between component legs or Mid-Chip.
Even
though activator performance or Solderability issues can
magnify this phenomenon Gel instability can be clearly demonstrated
when high boiling point solvents are used to improve tack
and stencil life.
The
synthetic gel system adopted by Microprint offers stability
at least 60°C higher than conventional gel. This yet
again adds to the compatibility of Microprint with eco friendly
'lead free' applications.
Profile
Friendly
By carefully
monitoring activator performance at different profile temperatures,
Warton have succeeded in making Microprint profile friendly
for lead free processes. With careful manipulation, the
same activator package can provide excellent activation
at lower temperatures and can offer sustained activity for
higher or longer temperature profiles.
This
profile friendly approach allows the engineer to set the
profile optimally for the process and defect minimization-and
not the solder paste.

VOC
Free Printing Operations
Advancement
in solvent package technology means that during the printing
and placement process Microprint is rated as VOC FREE in
accordance to the European Solvent Directive, by which a
VOC is defined by vapour pressure. This definition defines
a VOC as having a vapour pressure of >0.1mbar. This definition
applies to all industry sectors and is aimed at minimizing
emissions of VOCs.
Cleanable
after Reflow?
Yes,
cleaning agents can readily remove the residues of Microprint
P2006. Saponifiers such as Warton Metals Ltd TOTAL CLEAN
600 or TOTAL CLEAN 612 can easily remove all residues without
leaving white staining or crystals normally associated with
traditional rosin based pastes, recommended conditions can
vary from 25-60°C for 2-5 minutes. Solvent cleaners
can also be used such as TOTAL CLEAN 440 or aerosol cleaner
TOTAL CLEAN 200. Stencil cleaning is simple with either
TOTAL CLEAN Stencil wipes or TOTAL CLEAN 130 Stencil Cleaner.
