Thickness of adhesives applied
Keep thickness of adhesives applied (50-105 m or more)
to reinforce the adhesive contact considering the
thickness of the termination or capacitor (20-70 m) and
the land pattern (30-35 m).
Mechanical shock of the chip placer
When the positioning claws and pick-up nozzle are worn,
the load is applied to the chip while positioning is
concentrated in one position, thus causing cracks,
breakage, faulty positioning accuracy, etc.
Careful checking and maintenance are necessary to
prevent unexpected trouble.
An excessively low bottom dead point of the suction
nozzle imposes great force on the chip during mounting,
causing cracked chips. Please set the suction nozzle's
bottom dead point on the upper surface of the board.
conditions needed for soldering.
Continued from the preceding page.
Depending on the conditions of the soldering
temperature and/or immersion (melting time),
effective areas may be lost in some part of the
terminations.
To prevent this, be careful in soldering so that any
possible loss of the effective area on the terminations
will securely remain at a maximum of 25% on all
edge length A-B-C-D-A of part with A, B, C, D, shown
