I always covered eproms when doing service work. Even though the circuit board was mounted in a dark cabinet. I put a piece of tape over the window.
Here's a fun fact also. Something to think about at times. But only curious. With all the high velocity particle emissions in space. Voyager 1 and 2. Those 2 space craft still speak. What's up with that? All it takes is a randomn particle to disrupt the Depletion Zone in a transistor base region. This is well known. Just knock an electron out of oribit. Change a digital 1 to a digital 0. Change a transistor from on to off. (Forgive me for over simplification ). Thus the data is changed. Yes. Encryption techniques exist to recover compromised data. But. That is way out of my league when those 2 that were launched. Note. Modern day encryption is so reliable.
My point. NO POINT. Just posting a fun fact.
Here to learn like everybody else.
My evaluations are my own opinion.
