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).

CAUTION

To avoid the risk, it is essential to use only feeders that have

been approved for placing such components, namely:

Article no.: 00141117-01 Model E

Article no.: 00141118-01 Model C/D 2

The feeders are labeled as shown

2.2.1.1 General

The gantry positioning range is covered by two protective covers. If you want to open the protec-

tive covers, first press the Stop button (item 1 in Fig. 2.2 - 2

) or the emergency stop mushroom-

head push-button (item 2 in Fig. 2.2 - 2

). The power to the gantry axes will be switched off and the

gantries will stop immediately. 2

If you open one of the protective covers or a guard on the incoming or outgoing conveyor, the

power to the gantry axes will be switched off and they will stop immediately. 2

If the key switch is closed (position I), you can continue to pace the star at reduced speed while

the protective covers are open. 2

Placement will stop if you press the emergency stop button. You can then either cancel or continue

placement of the PCB. The protective covers at the sides can be opened in order to refill with com-

ponents when the machine has stopped. 2

WARNING

The protective covers must only be opened, with the key switch closed (position I), by appropri-

ately qualified and trained personnel. 2
