Summary

Description
English: This is an Xbox 360 graphical processing unit that was desoldered from an Xbox 360 motherboard. The photograph shows the risks of desoldering ball-grid array components without proper procedures. Here you can see that moisture in the circuit board turned to steam when it was subjected to intense heat. This produces the so-called "popcorn effect." You can prevent this by using a fast-acting solvent such as methyl ethyl ketone as well as preheating the circuit board using an oven.
