Ok guys, I have piled up a lot of ic chips and I am ready to get these incinerated. I see a lot of guys processing IC chips but I am wondering how everybody takes precautions in dealing with (possible) beryllium(oxide) dust.
I am always more than careful in dealing with escrap. I even depopulate my boards in a dust free box (see pic) with hammer an chisel. All the chemistry I do I perform in a professional fume hood and I always wear gloves, safety glasses and lab coat.
Eveybody is, of course, interested in gold contents, but I am also interested in beryliium content of IC chips. Who has more information about this subject. My information is that some of the (springy) copper like cpu sockets contain around 2% beryllium metal. Beryllium oxide could be present in components that require good heat conductivaty. Is there berylium present in the epoxy of these kind of chips, like BGA?
Please help me with information, we could all benefit from this.
