Do not allow modules with chargeable and highly insulating materials to touch one another, e.g.
plastic films, insulating table surfaces or items of clothing made from synthetic fibers.
Always place the modules on a conductive surface (table with an ESD coating, conductive ESD
foam, ESD bag or container).
Do not bring modules near visual display units, monitors or televisions. Keep them at least 10 cm
away from the screen.
2.10.4 Measurements and modifications to ESD modules
Do not take measurements on such modules unless
– the measuring device is earthed (e.g. via PE conductors) or
– you discharge the measuring head just before taking measurements with a potential-free mea-
suring device (e.g. by touching an unpainted metal part of the controller casing).
Æ Always use an earthed soldering iron if you carry out any soldering work.
2.10.5 Dispatching ESD modules
Always store modules and components in conductive packaging (e.g. metallized plastic bags or
metal sleeves) and dispatch them in conductive packaging.
If the packaging is not conductive, place the modules in a conductive envelope before packaging.
Use conductive expanded rubber, ESD bags, domestic aluminum foil or paper, for example.
NEVER use plastic bags or film.
If the module has integral batteries, ensure that the conductive packaging does not touch or short-
circuit the battery terminals and, if necessary, first cover the terminals with insulating tape or ma-
terial.

3.1 Description of the machine
The placement machine is a high-performance placement system with one gantry. It holds a 6-
segment Collect&Place head, a Pick&Place head and a PCB camera.

The placement heads pick up components from stationary feeders and use them to populate the
PCB clamped on the PCB conveyor.
The 6-segment Collect&Place head equipped with a component camera can process size 0201
to 18.7 mm x 18.7 mm components.
The Pick&Place head is particularly suitable for placing fine pitch components. It places compo-
nent sizes ranging from 1.6 mm x 0.8 mm to 55 mm x 55 mm. In addition to the PCB centering
vision module, the placement machine also has component vision modules for the Collect&Place
head and Pick&Place head.
The concept behind the automatic placement system
– with its stationary feeders,
– PCBs that do not move during placement
– and positionable placement heads
has a number of significant benefits:
– For example, the flexible 6-segment Collect&Place head combined with automatic nozzle
changer enables the nozzle configuration to be changed temporarily and automatically
adapted to receive different component sizes. The same applies to the Pick&Place head. You
can also optimize the traversing paths and the placement sequence.
– With stationary feeders, even the tiniest components are picked up reliably.
– The components cannot slip on the PCB during placement (as is often the case with moving
PCBs) since the PCB does not move.
– Sophisticated optical centering systems (vision modules) for components and PCBs also en-
sure high component positioning accuracy.
– Components can be topped up and tapes can be spliced without stopping the machine.
– Prepared component trolleys enable the placement system to be retooled without long stop-
pages.
A waffle-pack changer may be used to supply components.
