1.2.4 ESD guidelines
1.2.4.1 What does ESD mean?
Almost all of the modules in use today are equipped with highly integrated Metal-Oxide-Semicon-
ductor (MOS) blocks and components. The manufacturing techniques used mean that these elec-
tronic components are extremely sensitive to overvoltage and thus to electrostatic discharge.
The abbreviation for such modules is 'ESD' (Electrostatic Sensitive Device).
’ESD’ is used internationally. The following symbol on cabinet rating plates,
racks or packaging indicates that components which are sensitive to electro-
static discharge have been used and thus that the modules concerned are also
touch-sensitive.
ESDs can be destroyed by voltages and power levels that are far below the level that can be per-
ceived by humans. Such voltages occur if a person touches a component or module without
earthing themselves. Components that are exposed to such overvoltage do not generally appear
to be defective immediately - incorrect behavior starts after the component or module has been in
operation for some time.
1.2.4.2 Important measures to protect against static charging
► Most plastics can easily become charged and must therefore be kept away from at-risk com-
ponents.
► Always ensure that people, the workplace and packaging are safely earthed when handling
electrostatic sensitive components.
1.2.4.3 Handling ESD modules
Do not touch electronic modules unless it is absolutely essential to do so in order to carry out other
work. If it is necessary, make sure that you do not touch the pins or printed conductors when you
pick up flat modules.
Do not touch components unless:
●
You are constantly earthed by an ESD wrist strap or
●
You are wearing ESD shoes or ESD shoe earthing strips on an ESD floor.
Always discharge yourself before you touch an electronic module. To do this, simply touch a con-
ductive and earthed object immediately before you touch the module (such as unpainted parts of a
switch cabinet, a water pipe, etc.).
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 move the assemblies near to data view devices, monitors or television units. Keep a min-
imum distance of 10 cm to monitors.
1.2.4.4 Measurements and modifications to ESD modules
Do not take measurements on the modules unless the following conditions are fulfilled:
●
The measuring device is earthed (e.g. via PE conductors) or
●
You discharge the measuring head just before taking measurements with a potential-free
measuring device (e.g. by touching an unpainted metal part of the controller casing).
► Always use an earthed soldering iron if you carry out any soldering work.

1.2.4.5 Dispatching ESD modules
► Always store modules and components in conductive packaging (e.g. metalized 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 pack-
aging. Use conductive expanded rubber, ESD bags, domestic aluminium foil or paper, for ex-
ample. 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 material.
1.2.5 Validity of document
This document contains service work instructions for all SIPLACE C&P20 P and C&P20 M2 place-
ment head types.
The service work described in this manual is largely identical for all placement heads:
●
If the work required should differ from the standard procedure, this will be indicated with refer-
ence to the head type and/or the serial number.
●
Diagrams should be seen as examples e.g. the diagram of a different paint finish does not
mean that the following information only applies to the type shown.
The manual focuses on describing mechanical service work.
Please refer to the circuit diagram folder for any electrical checks.
