2.5 ESD-sensitive Components
Guidelines for Handling Electrostatic Sensitive Devices (ESD)
NOTICE
ESD Sensitive Equipment
● Always be aware of electrostatic discharge (ESD) when working near or touching
● Always transport static sensitive equipment in antistatic bags.
● Always use a soldering iron that has a grounded tip. Also, use either a metallic vacuum-
● Ensure that anyone handling the printed circuit boards is wearing a properly grounded
● Static charge build-up can be removed from a conductive object by touching the object
● When handling a PC board, always hold the card by its edges.
● Do not slide printed circuit boards (PCBs) across any surface (e.g., a table or work bench).
● Avoid plastic Styrofoam™, vinyl and other non-conductive materials. They are excellent
● When returning components to Siemens Industry, Inc. always use static-safe packing.
Components that can be destroyed by electrostatic discharge (ESD)
NOTICE
Electrostatic discharge
Electronic components can be destroyed in the event of improper handling, transporting,
storage, and shipping.
Pack the electronic components in appropriate ESD packaging; e.g. ESD foam, ESD
packaging bags and ESD transport containers.
To protect your equipment against damage, follow the instructions given below.

components inside the VFD cabinet. The printed circuit boards contain components that
are sensitive to electrostatic discharge. Handling and servicing of components that are
sensitive to ESD should be done only by qualified personnel and only after reading and
understanding proper ESD techniques. The following ESD guidelines should be observed.
Following these rules can greatly reduce the possibility of ESD damage to printed circuit
board (PCB) components.
style plunger or copper braid when desoldering.
static strap. The wrist strap should be connected to ground through a 1 Megohm resistor.
Grounding kits are available commercially through most electronic wholesalers.
with a properly grounded piece of metal.
If possible, perform PCB maintenance at a workstation that has a conductive covering that
is grounded through a 1 Megohm resistor. If a conductive tabletop cover is unavailable, a
clean steel or aluminum tabletop is an excellent substitute.

This limits any further component damage due to ESD.
