1 Read this first!
CAUTION
 Before you start replacing any components, make sure you have read and fully understood
the contents of section 2 and 3!
• Also make sure you have access to the mechanical Working Instruction and the equipment
listed on the first page of section 4!
• Use Electrostatic Discharge (ESD) equipment to avoid damaging the PBA.
• Use gloves or finger cots to avoid contaminating the PBA with skin oil.

2 Lead-free soldering
KEEP ALL CONTACT SURFACES CLEAN OF DIRT AND HAND
GREASE!
THIS PRODUCT IS MANUFACTURED WITH LEAD-FREE SOLDER
AND LEAD-FREE COMPONENTS!
During electrical repair, it is critical to make sure that no
lead is introduced.
This symbol indicates that the product is lead- free.
All lead-free PBA will be marked with this symbol.
A lead-free work area must be set up completely separated
from work areas that are used to make lead repairs.
The lead-free work area must also be clearly labeled with
the lead free symbol as shown in the adjacent picture.
The items on this desk must remain lead-free.
They must be adequately labeled to make their lead-free
status clearly and easily recognized.

Lead-free soldering continued
LFS (lead-free solder paste) characteristics:
•High melting point (typically 220°C)
•Low wettability
•High surface tension
•Difficult to spread
•Recommended tip temperature = 360°C
WHEN SERVICING PBA’S THAT HAVE BEEN MANUFACTURED
WITH LFS (LEAD-FREE SOLDER PASTE), LFS MUST BE USED.
IF NOT,THERE IS A HIGH RISK FOR UNRELIABLE SOLDERING
JOINTS.
Lead-free solder joints are more difficult to inspect because
they do not have shiny surfaces like leaded solder joints.
Also, lead-free solder does not flow as well as leaded
solder, so some of the solder pad areas may remain
exposed.

3 Soldering issues
3.1 Hot air gun temperature requirements
The air temperature must not exceed 360oC.
The temperature shall be measured 5 mm from the nozzle outlet.
If it is not possible to remove and/or solder with 360oC, a BGA Rework Station or another repair
process must be considered to ensure high process control.
A temperature being too high can cause damage and cracks due to the thermal stress on sensitive
components, e.g. ceramic components like capacitors.
3.2 Soldering tip temperature requirements
The soldering tip temperature must be minimum 310oC and maximum 360oC.
A temperature being too high can cause damage and cracks due to the thermal stress on sensitive
components, e.g. ceramic components like capacitors.
3.3 Bottom heat requirements
In certain cases some components may require a bottom heater during repair in order to pre-heat the
board and to level out the UT on the PBA.
This will also minimize the thermal stress.
The temperature on the PBA surface must not exceed 150oC to minimize inter-metallic growth and
thermal stress on the PWB.
3.4 BGA rework specifications
For all components that require the use of a BGA Rework Station, follow the:
Technical Requirement, Generic document; Space ID: 1207-2949
and
Heat treatment document; Space ID: 1210-5414

4 Shield fence instruction
This instruction shows how to cut and bend the shield can
fence to be able to replace components under the fence.
Use a sharp-edged pliers to cut the fence.
Use Shield fence pliers NTZ 112 537 to bend the fence.
MAKE SURE THAT CUTTING PLIERS IS SHARP-EDGED TO
PREVENT DAMAGING THE SHIELD CAN FENCE.
Remove the shield can lid, use a dentist hook.
Remove the pick up area according to the white lines with
a cutting plier. (1)
This pick up area is only used when machine mounting
and there is no need to put it back again.
Cut the shield can fence according to the white lines with
a cutting plier. (2)
Carefully bend the shield fence with a shield fence plier.
Replace the components.
Replace the components.
Bend carefully back the shield fence.
