Electronic – How to read the text printed on top of every IC


I find very difficult to read part numbers. I haven't figured out how which kind the ideal amount of light and inclination would help me.

I also wonder why chipmakers don't paint the numbers in white for a better contrast.

1. Clean up the text with a cotton swab dipped in rubbing alcohol.
