Working on 545grams of ram card fingers. I've searched the past forums and entered the question I'm looking for several different ways. Anyhow...it seems like I was told in the past to incinerate ram foils until they turn red in color. By doing this it will eliminate the Tin in the remaining gold foils. Is this true. Thank you and hope to get some great answers. I'm in no rush....I've learned messing with this stuff. PATIENCE

There should not be any tin on foils from RAM fingers.

Incinerating does not "eliminate" tin. It converts it to an oxide that will not cause problems.

I think that process is more for dealing with metastatic acid (Tin nitrate). As for your foils, that shouldn't be too much of an issue as long as you rinse the foils well.

Hcl and a tiny bit of bleach at a time will dissolve the foils easily, filter and drop with your preferred method.

There is also more Au in the IC chips on the ram sticks.

Welcome to our corner ;)
If you can take a straight answer not wrapped in cotton, this is an awesome place to learn, most likely the best.

But as have been said already incinerating the PCB will not do anything bad per se.
Then the ifs come.
If all the carbon has been burnt off and so on.

There should not be any Tin, if the fingers are closely cut to the plating,
and as long as you do not use Nitric it does not even matter if there is a bit of Tin.

Use Copper Chloride etch aka AP to dissolve the copper backing and the foils loosens.
Flush it from the PCBs with a spray bottle and collect them in a small beaker.
Then you dissolve with HCl/Peroxide HCl/Bleach or similar.

Anyway, there are months worth of threads on this subject, so after you have read Hokes book and searched the forum,
you should have acquired enough info to get a hunch of what you don't know.

Thank you for the reply. I can't remember we're I heard or read to incinerate ram foils until they become red in color to rid them of Tin.
 
I've been reading past topics. And I have a few computer and TV screens. My question is, where can I find these pictures?
Sadly some images was hosted from external sources that no longer exist.
And you are right, I have never heard of roasting/incinerating Ram fingers either.
A quick "roast" to burn off oils/grease/contaminants can be a wise move though.
But that is just heat until red and stop.
 
Thank You for the reply in regards to the pictures. Again I can't remember where I read it, to incinerate ram foils until red in color. Regardless I do incinerate the ram foils/filter I capture them in.
