2.1.15 Safety instructions for processing capacitors based on powdered metal
There is a risk associated with processing capacitors based on powdered metal (e.g. tantalum). 2
The risk is that 2
– 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
build-up 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. 2
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. 2
The ambient conditions are unfavorable if: 2
(1) The components remain on the tape while the set tape cycle is checked (since the operator
can cycle the feeder 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
specification, thus increasing the pick-up error rate.
Please follow the instructions given below to minimize the risk when placing capacitors based on
powdered metal. 2
(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.
(3) The waste tape container must be emptied regularly (recommended interval: every hour).
2
CAUTION
To avoid the risk, it is essential to use only feeders that
have been approved for placing such components,
namely:
Article no.: 00141118-01 Model C/D
Article no.: 00141117-01 Model E 2

The feeders are labeled as shown

The travelling range of the gantries is covered by four protective covers which can be folded up.
Side screens prevent access to the inside of the placement system from the side. The covers over
the input and output belts of the PCB conveyor and the guards on the input and output belts pre-
vent access to the PCB conveyor. 2

Function
If one of the protective covers is folded up or one of the covers on the PCB conveyor is raised, the
power supply to the gantry axes will be interrupted immediately. The gantry axes will stop and the
message "Close the cover" will appear on screen. 2
Æ Close the protective covers and press one of the Start buttons to continue placement.
