2.5.3 Safety instructions for processing capacitors based on powdered metal
There is a risk associated with processing capacitors based on powdered metal (e.g. tantalum).
The risk is that
– an exothermic reaction, i.e. a sudden build-up of heat, may occur, if these components are
damaged. If the ambient conditions are unfavorable, and depending on the capacitance, this
buildup of heat can cause damage.
– This effect can occur when these components are cut.
Please contact your suppliers to clarify whether the components that you handle are affected.
In extremely rare cases, this risk can occur in the tape cutter of SIPLACE machines, with the re
-
mote possibility of causing a smoldering fire in the waste tape.
The ambient conditions are unfavorable if:
(1) The components remain on the tape while the set tape cycle is checked (since the operator
can cycle the feeder module onward without removing components during this check).
(2) The components remain on the tape, e.g. due to a tear in the cover foil.
(3) The components remain on the tape, and the components or tape do not conform to the spec
-
ification, thus increasing the pickup error rate.
Please follow the instructions given below to minimize the risk when placing capacitors based on
powdered metal.
(1) If the component tape is cycled onward manually, the operator must remove any components
remaining in the tape pocket.
(2) If the cover foil tears, the operator must remove any components remaining on the tape.
To prevent tantalum capacitors which were not picked up from causing the tape material to burn
when it is cut, the user interface has been extended to include the option "Stop immediately on
pickup error". This option must be enabled in SIPLACE Pro. On the placement machine, the com
-
ponent that was not picked up is paced forward again until it is ready for removal from the com
-
ponent tape. The track is deactivated and the operator is sent an error message to remind him to
pick up the tantalum component from the tape.

PLEASE NOTE
Manual removal of tantalum capacitors not picked up
A description of how the operator can manually remove those tantalum capacitors which
were not picked up can be found in section 3.8.1.3
, page 146.

Fig. 2.5 - 2 Risk of crushing by return unit on SIPLACE TH/SIPLACE PP
(1) Return unit, compressed air cylinder
(2) Piston rod
(3) Bumper of the return unit
(4) Risk of crushing finders here
CAUTION
Risk of crushing on SIPLACE TH/SIPLACE PP!
The strong spring tension of the cylinder moves the buffer back very quickly and could
injure your fingers. The same warning applies to the inside of the SIPLACE TH or SI
-
PLACE PP, when the piston rod moves back to its original position.
NEVER move the Z axis down with your hand at the buffer of the return unit.

2.5.6 Safety instructions for correct fitting of the reject bin
Observe the following instructions to avoid risk of collision between the placement head and com
-
ponent or the nozzle reject bin:
Make sure, that the reject bin is seated correctly in its mount.
Check that the reject bin does not project over the mount.
2.5.7 Safety instructions for using the nozzle changer
Observe the following instructions to avoid risk of collision between the placement head and the
nozzle changer.

PLEASE NOTE
Requirements for ESD safety of machines
Only use nozzles that are identified as conductive.
WARNING
Risk of head crashes with mixed configurations!
There is a risk of head crashes with mixed configurations.
Only install the associated nozzle changer for each placement head, with the nozzle
magazines for the respective placement head.
WARNING
Risk of head crashes with protruding lever!
A lever which projects above the magazine could lead to a placement head crash.
You should therefore make sure that the lever does not protrude over the magazines.
