MP200 solder pastes have been formulated as no-clean,
Sn/Pb solder paste for high speed printing and reflow in both
air and nitrogen. The product was specifically formulated to
have increased reflow operating window.
FEATURES AND BENEFITS
Suitable for fine pitch, high speed printing up to 200mms
-1
Extended printer open time and tack life
Long abandon time
Colorless residues
Soft residues make pin testing easier eliminating any need for
cleaning
● Resistant to both hot and cold slump
● 63S4 alloy for Anti-Tombstoning
● Halide free flux classification: ROL0 to ANSI/J-STD-004 (Jan.
1995)

TYPICAL PROPERTIES
Solder Powder:
Careful control of the atomisation process for production of
solder powders for MP200 solder pastes ensures that the
solder powder is produced to a quality level that exceeds
IPC/J-STD-006 & EN29453 requirements for sphericity, size
distribution, impurities and oxide levels. Minimum order
requirements may apply to certain alloys and powder sizes, for
availability contact your local technical service helpdesk.
DIRECTIONS FOR USE
Printing:
1. MP200 is available for stencil printing down to 0.4mm
(0.016") pitch QFP devices, with type 3 (AGS) powder.
2. Printing at speeds between 25 mm/s (1 "/s) and 200 mm/s
(8 "/s) can be achieved using laser cut, electropolished or
electroformed stencils and metal squeegees (preferably
60°).
3. Unlike some pastes, high squeegee pressures are not
required, making Multicore MP200 particularly useful for
second side printing processes.
4. Acceptable first prints have been achieved at 0.4 mm (16
mils) pitch after printer down times of >90 minutes without
requiring a knead cycle.
Reflow:
● Any of the available methods of heating to cause reflow
may be used including IR, convection, hot belt, vapor
phase and laser soldering.
● There is no single reflow profile which is suitable for all
processes and applications, but the following graphs
show profile examples that have given good results in
practice.
● 63S4 anti-tombstoning is selected when tombstone
defects are experienced with standard alloys and when it
is not possible to eliminate by design changes..

63S4 ANTI-TOMBSTONING ALLOY
63S4 alloy offers an instant solution where tombstoning is a
particular process problem. 63S4 alloy is a blend of different
melting point alloys with a special mix of solder particle sizes.
This modification extends the melting range of the alloy
reducing the possibility that one solder deposit at a component
termination can fully reflow before the other.
