(4)Should be no seriously collapsing problem and edges neatly after solder paste had been printed, the dislocation shouldn’t
be larger than 0.2 mm, for solder pad of fine pitch components, dislocation shouldn’t be larger than 0.1MM, pollution by
solder paste is not permitted to the PCB.
Inspection by 2~5 times magnifier or 3~20 times microscope.

12.3.3

The defects of solder paste printing, reasons andsolutions

Excellent printing graphics should be uniform in both vertical and horizontal direction, full, clean all round, solder paste fill
solder pad. Using above such printing graphics device, after reflow soldering, will get good welding effect then.

Problem

Reason

Issue

Solution

Solder paste
graphics
dislocation

Holes on the stencil not good
match with solder pad; No
enough precision of the Printing
machine

easily cause bridge
connection

Adjust the stencil position;
Adjust the printing
machine

Solder paste
graphics have
icicles and dents

Scraper pressure is too large;
Rubber scraper hardness is not
enough; Holes are too big in the
stencil

Solder paste required
volume is not enough,
easy to appear faulty
soldering; solder joint
strength is not enough.

Adjust the printing
pressure; Use metal
scraper; Improved holes
designing in the stencil.

Too much solder
paste

Holes are too big in the stencil;
The gap is too big between
stencil and PCB

easily cause bridge
connection

Check the holes size in
stencil; Adjust the
parameters of printing,
especially the gap between
PCB and stencil

Graphic uneven
(have
breakpoints)

Holes’ wall are not smoothness
enough; not wipe residual solder
paste in using for many times;
Solder paste’s thixotropy is bad

Easy cause no enough
solder paste, lead to the
problem such as faulty
soldering.

Wipe the stencil

Contamination of
the graphics

Not wipe residual solder paste in
stencil after using for many
times; Poor quality of solder
paste; Shake problem when
getting the stencil way

easily cause bridge
connection

Wipe and clean stencil;
replace solder paste; adjust
the machine
