Is Magnetic damage a real thing?

So I use a magnetic mat, for keeping screws and such organized, and not running away from me, during repairs. If I put a part, let's say, a lcd/digitizer assembly. Would that hurt the part? I've done it many times, and had no problems. But, every once in awhile, it seems like it does. Any ideas?

The little bit of magnetism in a mat of your screw drivers poses very little risk. However, I would not place RAM on it because of its finicky ESD propensity.

So don't put the phone on it?


I see no problem with a phone.


Thanks for responding. What could my mat damage?


A powerful rare earth magnet or electro magnet can damage magnetic media and can also damage magnetic sensitive electronics like the compass unit in your phone. The low level magnetic properties of the mat won't hurt anything.


I agree with Mayer here, ESD is more likely the issue than magnetism from the mat. Are you following proper ESD procedures?
