If you suspect an MB44C023 is cracked, visual inspection is rarely enough, as the crack is often underneath the chip or microscopic.
Set your hot air station to roughly with medium airflow.
Rapid, extreme temperature changes can cause the IC to crack due to uneven expansion rates between the chip, the solder, and the PCB (Printed Circuit Board).

Bring your hot air tool down vertically from a distance, slowly closing in at . Watch for the chip to automatically "surface tension snap" into place as the solder spheres melt and bind to the pads.
Add fresh leaded solder to the array of motherboard pads using a soldering iron to lower the overall melting point of the remaining factory lead-free solder.
Replacing an MB44C023 is not a beginner-level repair. It requires advanced microsoldering skills, as the chip is a BGA component. 1. Diagnosis If you suspect an MB44C023 is cracked, visual
