Most images in the Gallery Of Bad are pretty obvious as far as why they are included in the Gallery. However, we thought this example warranted being singled out for a bit further discussion.
This BGA device looks normal at first glance but take a closer look or better, feel the top of it with your finger and the problem will be revealed. Directly under the characters “6EG00825” there is a slight bubble in the center of the component package that is barely visible with normal inspection. If you feel the top with your finger you can detect the bubble quite easily.
Sometimes troubleshooting involves all of your senses.
