silver recovery from IC bga chips "How to make silver"
Ғылым және технология
Hello, friends @MakeGold
Today I will introduce the method of silver recovery from IC bga chips
lead-free solder is mostly silver, tin, and sometimes copper or other metals. The temperature required to get a lead-free solder alloy into its molten Pb-free solder materials are used in various parts of interconnections in electronic packages. The first-level interconnectis between the chip and the package substrate and lead-free solder bump material are used in the case of a Flip Chip BGA (FCBGA).
solder ball Where we are interested and there is a silver mixed.
Use nitric acid mixed with water to dissolve the solder ball.
Using copper to precipitate silver.
Use hot water to clean the silver silt powder.
Dry the silver silt powder.
Melt the silver silt powder.
Sprinkle a little borax powder.

Hello, friends Silver sedimentation method. 1. use salt 2. use copper Is a simple way for you to bring the silver solution back into the silver metal again. Thank you for watching our video and commenting.

Hello! That was awesome!!😃😃🏆🏆🏆 I have a question? Can this be done using something other then nitric acid? I was thinking of trying AP but not sure how I would do the precipitation of silver. You are one of my favorite channels! 🏆🏆🏆🎖🌞
is there only silver in solder on bgas or in all solder used in computers ?
Hi sir nice video and the tin by gold recovery video upload sir please thenk you sir
The rest of the blue, you could Drop in a little peroxide then so sodium metabisulfite, to take more old out.

Hello, before placing the copper to precipitate the silver, do you need any solution to neutralize the nitric acid?

No, the copper will consume the acid
Your nitrate is very milky. You might actually be leaving silver behind with it being that cloudy.
will this work other solder parts
What about the gold on the bga chipps ? You don't recover the gold first ?

gold doesnt dissolve in nitric acit, the gold will be still on the chips and or gold foils will float around not dissolved in his first step, if gold is present

You said to use water and nitric acid in a ratio of 1:1. However, your video appears to use almost 100ml HNO3 and close to 250 ml water. Am I correct?

I think it is because it is an electrolytic reaction so it needs an electrolyte like salt, the metallic copper displaces the metals (like silver or tin) that were in the nitrated liquid

Nitric acid alone won't dissolve gold so it will remain as a solid .

It's a chloride salt of some sort. Silver nitrate will react with chloride salts to form silver chloride and various nitrate salts. The silver chloride isn't very soluble, and it makes a kind of milk-like solution because the precipitate is so thick. Generally speaking any sort of chloride salt will work, but Sodium chloride is extremely common, so that's what it tends to be.

I heard this before and still don't know if it's true. Not to say your wrong at all , but I don't know I've take apart a lot and I mean a lot of really old electronics and I think I may have only seen a couple that didn't react and stick to a magnet. Also there's not many I removed that were in the presence of a magnet either. I just did that once to sheer everything off of the boards with a hammer and a wide paint scraper.

How to silver recover from fixer by chemical.
Hmm.. So, it's about $1 of silver per 100g of CPUs that don't have heat spreaders attached. CPUs with most of their weight in the copper spreaders are selling for $2.65 per 100g, or probably 6x as much as their silver value. Copper is worth nothing compared to silver, so... hmmm... Still need friends to be successful it seems.
