PC/Electronics IC Chips how to remove?

Theres no places close to me that buys the chips or boards. There is a escrap place but thats too far away & their prices are rubbish anyway.
By removing the copper legs it makes it easyer to process.

Oh, & if posting that info saves a few people from cutting the end of their fingers off.... Safety first.

I will use a small belt sander to remove the legs.



I just found out that you can reclaim 10gms of gold from 7Kg of flatpacks.

Yeah, I am that guy who did that experiment.
A little clarification is due - I processed whole mix of IC chips in that experiment (s/n bridges, ram chips, eprom like chips, ...... practically whatever size black plastic IC from electronics)

Since then (august 2011) I did many another batches but this time I separated chips to different types and sizes.
Gold yield is then different. South/North bridge - the ones with black plastic cap and green fiber bottom yield 5g+ of gold from one kilogram. I consider them as the best from IC comonly found in modern electronics. There are certain Russian made IC chips which are like gold mine but it is increasingly hard to find them and soon they may have bigger value as collector items.
I try to separate or categorize IC chips in few types:
1. s/n bridge - high grade
2. ram chips - medium to high grade
3. all other thin IC - medium grade
4. thick two sided eprom like IC - low grade

I buy IC chips or I toll refine them but this is little bit out of question for most of members as I am located in Ireland and shipping, insuring and custom charges makes them more expensive in larger quantities. However we can talk about that and we may find some way.
Pat.

For better understanding of my classification of IC chips as in previous thread

s/n bridge

ram chips

mixed but thin chips

eprom like chips
