if i wanted to have somone refine smds would it be good for me to crush them into a powder first?

Geo said:if you are working with MCC's theres no need to crush, just dissolve in hot hcl acid. chips and flat packs should be either broken apart or ground or milled.
you are referring to cupelling, right? Ive been following a thread by NoIdea about cupelling. he mills the whole board. does this recover more silver than dissolution? i use AP alot and some of the black powder left is silver released from the solder im assuming but feel that im losing more by dissolving all solder this way.samuel-a said:Geo said:if you are working with MCC's theres no need to crush, just dissolve in hot hcl acid. chips and flat packs should be either broken apart or ground or milled.
While it will work for the Pd... This is a sure way to lose the silver and platinum in the white milky slurry...
At small scale, this would probably be better method.
But if i would to recover Kilos of MLCC's, milling and smelting with lead powder (collector) would be the way i'd choose.
In some cases, silver can go up even to 10% of total mass.

How are you planning to mill the SMD's?

In electronic litterature, the term used is MLCC for Multi Layered Ceramic Capacitors. It covers components both with leads and as SMD.Geo said:MCC = monolithic ceramic capacitor. PC's are loaded with them and even some low grade electronics have a large amounts of SMD's.
