9.2 Board Level 2.5 Repairs
Basic Repair Instructions for Component Replacement:
Step 1 Place the solder-proof tape to cover the surrounding area of the components which being replaced.
Warning：DO NOT overheat the tape and components to avoid the tape melted and the components damaged
Step 2 Use Heater Gun (HAKO850B, set the temperature between 3 50°C, Air Speed 3 ~ 5) to remove the
components.
Step 3 Wait till the temperature cool down before removing the solder-proof tape to avoid other components
being removed
Step 4 After the damaged or defective components have been repl aced; clear the surroundings for solder
and flux residues.
Notice:
A03
A. Checking the polarity of CON8, and the position can't be shifted.
B. Checking the polarity of SW8、SW7, and it can't be reversed.
C. All the parts of the PCB should be checked if it is missing or not.
D. The OP must to wear antistatic wrist band .Don't put boards together and avoid hitting them.
E. When you solder and repair that the soldering iron ,temperature must be setup 415 .℃ (The
temperature range is 415 ±5 ),and the solder wire's diameter is 0.4/0.5/0.6mm℃℃ (SAC 305 (1.1%)
F. Please be noticed to follow below steps for main board repair which is equipped with Golden
Capacitor:
1. When replacing level 2.5 components located around the golde n capacitor:
I. The temperature of the hot air blower must be under 400°c
II. When apply the hot air to the part / component, the heating time must be under 20
seconds (including the time of removing and soldering)
III. The temperature of the soldering iron must be under 350°c
IV. When apply the solder tip to the part / component, the heating time must be under 5
seconds
V. The solder tip must not contact with the golden capacitor
2. For BGA replace ment: The golden capacitor must be removed before perform pre-heating,
heating, soldering and de-soldering process, and then it must be replaced with a new one
(please refer to 1.c. and 1.d. steps)
3.
For main board which failed to pass the function test, the golden capacitor mu st be replaced
with a new one and must follow below soldering criteria: The temperature of the soldering iron
must be under 350°c When apply the solder tip to the part / component, the heating time must
be under 5 seconds The solder tip must not have a cont act with the body of golden capacitor
