SFC05-5
Printed Circuit Board Finish
A uniform board finish is critical for good assembly
yield. Two finishes that provide uniform surface coat-
ings are immersion nickel gold and organic surface
protectant (OSP). A non-uniform finish such as hot air
solder leveling (HASL) can lead to mounting problems
and should be avoided.
Stencil Design
A properly designed stencil is key to achieving ad-
equate solder volume without compromising assembly
yields. A 0.100mm thick, laser cut, electro-polished
stencil with 0.275mm square apertures and rounded
corners is recommended.
Reflow Profile
The flip chip TVS can be assembled using standard
SMT reflow processes. As with any component, ther-
mal profiles at specific board locations can vary and
must be determined by the manufacturer. The flip chip
TVS peak reflow temperature is 230 ± 10 °C. Time
above eutectic temperature (183 °C) should be 50 ±
10 seconds. During reflow, the component self-aligns
itself on the pad.
Circuit Board Layout Recommendations for Suppres-
sion of ESD
Good circuit board layout is critical for the suppression
of ESD induced transients. The following guidelines are
recommended:
Place the TVS near the input terminals or connec-
tors to restrict transient coupling.
Minimize the path length between the TVS and the
protected line.
Minimize all conductive loops including power and
ground loops.
The ESD transient return path to ground should be
kept as short as possible.
Never run critical signals near board edges.
Use ground planes whenever possible.
