SOLDER PASTE
Solder Paste Survey
lines when responding to evolving
industry needs. 0
By Douglas J. Peck
M
any companies, particularly those updating their processes or
looking for alternatives to CFCs, require current information on the types and suppliers of
solder pastes. The following data has
been compiled from CFC-LINK, a
PC database that focuses on the selection of CFC alternatives.
In assembling this data, survey
forms were sent to 21 companies that
manufacture solder paste. Each company was asked to submit product information on its 60140, 6213612 and
63/37 tin, lead and silver alloy
products in common flux formulations. The extracts of the manufac-

turer’s data for 213 of these products are shown in the chart. The
number of pastes available continues to increase as solder paste manufacturers upgrade their product

of five different vendors.
The process line started with bare

SMT; through-hole assembly wit
axial, radial and DIP componentl
bottomside SMT; hand assembl

ianufacturing techniques.
With product life cycles also shrinkig, PCB assemblers must turn to
quipment suppliers that offer dediated integration services. To reap
le full benefit of their investment,
ich as higher quality levels, maxiium process yields, minimum prouction start-up times and the most

Perfluoronated CFC
Replacement Solvents
The Vertech line of solvents is based on
perfluoronated materials. These solvents
are non-flammable, evaporate rapidly,
have a low order of toxicity and make a
good universal surface cleaner. They offer a non-ozone depleting alternative to
CFCs. The Vertech Degreaser (no.
1691) is designed for removing lubricating fluids, hand oils, greases and similar
contaminants from metal, plastic, glass
and other types of substrates. The Vertech Defluxer (no. 1692) is formulated
to remove rosin-based fluxes (RA,
R M A and R), hand oils, silicones and
other common contaminants found in
electronic PCB manufacturing.

Prefluxed SIPAD PCBs facilitate the
application of high-density components
onto PCBs. Prefluxing the board at the
manufacturing facility allows the assembler to eliminate the screen and/or stencil process from the assembly area.
The assembler can receive the SIPAD
boards, peel the release sheet and place
the surface-mount components immediately. Fine-pitch components down to
0.3 mm may be hand assembled.
