Odd smell

[grance]

I have been noticeing it more and more when I am removeing MCC's from mother boards every once and a while I get this fruitey smell hard to realy discribe but fruity like a bag of jolly ranchers. I assume any smell is bad or is it just my imagination. Also i just use a flathead screw driver to remove them

excuse my ignorance, butt, what are MCC's please

monolithic ceramic capacitors for some reason I cant post a pic the image size isnt right but if you google image it youll see them

There is enough potential for toxic compounds in e-scrap that adequate ventilation would be prudent. Smelling anything couldn't be good.

i got the same , but to me it is more like a parfume , in my sometime conspiration mind i love to think theyr put a smell in the board, that way in case it heat to much and burn poeple wont be scare and just ask them self why it smell parfum suddently... but the real reason is unknow to me :lol:

Not all intriguing odors are healthy. As I've been told cyanide smells of almonds.

I've seen enough cockroaches in computers that I don't want to know what they smell like. Better safe than sorry.

Could be due to a type of coating that the manufacturer put on the PCBs, or the flux they used, possibly even an accidental drip of fluorocarbon oil got on there during the manufacturing process.

I worked manufacturing electronics for 13 years. The moisture resistant coating we applied to the boards kind of had a cake baking smell to them when hot.

Some of the fluxes we used smelled sweet.

Fluorocarbon oil also smells very sweet when over heated. The reason fluorocarbon oil may be used some times in electronics manufacturing is because it will not conduct electricity. So if accidentally dripped on the boards there is no worry of shorting it out.

But no matter the source, you have already received the best advice, if it has an odor its probably best not to breath it..

I agree with what's already stated, howevere did these smells ironically come from Apple equipment? :roll:

What was meant is that they are not MCC's they are MLCC's (Multi-Layer Ceramic Capacitor)

Maybe you're smelling the electrolyte or maybe it's discharging.

Since you're only using a screwdriver to remove them, I'm assuming heat is not the primary issue. I have noticed on a few motherboards a smell like they had picked up residue of an air freshener that had been used in proximity when the computer was operational. Have also seen a few that were OBVIOUSLY owned by heavy smokers, like heatsinks that were completely clogged with dust and debris as well as that familiar tar smell. Just an idea.

I also agree with earlier post about the ionized smell of possibly discharging several at a time, another possibility.

Yes MLCC's is what I ment and the smell seems to be just on the Blue solder masked boards not the green or red. mostly in the area of where the processer would be. So i just do them out side now
