2.3.3 Upacking components
Electronic components are vulnerable to Electro Static Discharge (ESD) damage.
When unpacking components, you need to wear a properly grounded ESD wrist
strap and contact the edge of components only.
Stop unpacking the box immediately if the components are found rusted or
dampened during the unpacking process. Give feedback to the local Raisecom
office after finding out reasons together with Raisecom engineers.
Pay attention to the following items in the process of unpacking components:
Take anti-static protection measures to avoid components damage.
Pay attention to the impact of environmental temperature and humidity.
Take the edge of the circuit board to avoid touching the PCB components and printed
circuits with hands.
Unpack components according to the following steps:
Step 1
Check each packing box of the components to see whether there is obvious damage.
Step 2
Wear an ESD wrist strap and make it grounded properly.
Step 3
Unpack each box and take components out, as shown in Figure 2-2.

Step 4
Check whether the components are damaged and choose the corresponding processing
method. Execute step 5 if the components need to be installed immediately; if not, execute
step 6.
Step 5
Put card on the surface of antistatic materials for electro discharge treatment, and then install
them.
Step 6
Pack the components again with original packing materials, and store them in a dry and cool
environment to avoid sunlight and interference from strong electromagnetic radiation source.
