Removing BGA Chips and Rebelling It Using Reball Stencil
Two methods
1st by applying balls with help of BGA station
2nd applying liquid paste PPD and heat with BGA blower
why is reballing required
1st method ( inserting BGA balls using stencils)
2nd method (using a direct paste application)

Practice 1
1. Datasheet Search any components
2. Read the motherboard schematics.
3. Identify the main components and circuit
4. The actual steps on the main measuring
5. Use the main test card
6. Using machines to load the BIOS ROM.
7. Check, Replace MOSFET
8. Alternative sources IC
9. Rather SIO
10. Rather Clock IC
11. Use the tool to the chipset leg
12. Replace chipset South, North with machines (Received technology transfer when a demand for this machine).
13. Test socket CPU with specialized tool.
14. Rather hard + chipset using a chip steamer (if required)
15. Introducing specialized tool such as CPU load fake, test socket, test card, chipset foot grid, foot soles chipset, as chip fat, bi to chip, chip maker
16. Connection between PC and Laptop mainboard.
16, 17 Problem, testing and repairing steps
Analysis pan:
1. No source size.
2. Shutdown boot order.
3. Fans spin, no boot.
4. Loss of clock
5. Loss of power CPU (Vcore)
6. Losing power and RAM bus ram
7. Loss of power chipset.
8. Loss of the reset pulse.
9. Signs of open sockets, chipset
10. Do not get USB, HDD
