Except for body temp, all temperatures are measured with thermo couples inside solder
joints, for better accuracy
Primary Factors for Successful Rework:
•Flux formulation and solder paste formulation and volume
•A capable thermal reflow profile
•Proper PCB pad solder preparation/wicking (clean-up of the residual solder
from the PCB pads)
Caution: Always remove batteries and thermal solutions following the system
design disassembly process steps prior to BGA rework to avoid damaging the BGA.
