PCB warpage downwards max. 0.5 mm
Use the magnetic pin supports, to achieve
this value.

When there is warpage under 2 mm, the
inkspots in the center of the board are also
within the focus of the digital camera. When
all the tolerances are taken into account,
this value is reduced to 1.5 mm.
You should also note that the warpage
reduces the component height.

Smart Pin Support
General
Wide boards tend to deflect
during placement such that,
under certain circumstances,
the components can no lon-
ger be placed with the
desired accuracy. Highly
curved PCBs also affect the
placement accuracy. This
problem can be easily recti-
fied by fitting support pins on
the lifting table.
Smart Pin Support
The support pins are auto-
matically placed on the lifting
table with the help of the
Smart Pin Support option. A
gripper unit is used to pick
the support pins up from spe-
cial magazines and place
them in the prescribed posi-
tions.
Before you place a smart
support pin, the placement
area is cleaned from any
contaminants with a gentle
blast of air. In addition, the
correct position of the sup-
port pins is checked after
placement, with the PCB
camera.
Magazines
There are two different mag-
azines available for auto-
matic changeover to max. 10
support pins in the various
machine configurations.
These magazines are fixed
to a magazine holder and are
fitted to the component trol-
ley docking unit.
Programming
The positions of the support
pins in the machine can be
defined for each board side,
in the SIPLACE Pro Board
Editor.
A 3D diagram of the board
and support pins allows you
to detect and avoid potential
collisions with components,
even during stepped trans-
portation of extra long
boards.
