@Lennong - I asked the seller if there is other problems and he informed me that "many on eBay buy CPUs in such condition, repair and resell them. We did not test these CPUs and not sure whether they are working without the capacitors as we did not want to risk damaging the motherboard I believe these can be carefully reworked." What is your opinion on this response ?
@Terry Kennedy - you are right it is the same eBay item put into 1 image for simplicity. Do you think it's worth buying and trying to repair?
Both of these questions depend on what the pair finally sells for - I've seen people bid things like this all the way up to (and sometimes beyond) what un-damaged CPUs would cost.
Regarding an earlier post about some sellers doing this sort of damage intentionally to sell dud chips, that is certainly possible. Or the chip could be some much lower-end part re-marked as a more expensive chip - in that case, the seller hopes you don't get it working, because if you do, you can open a complaint w/ eBay about "item not as described", since it has both pictures and text showing the model number and S-spec.
@Terry Kennedy -Since I can't pay you for fixing this, can I buy any cheaper equipment than a $1-2000 hot air rework to repair this ?
You really don't want to practice on these. If you're going to do it, buy some cheap processor and practice taking the caps off and putting them back on. It may also serve as a source for the parts you need.
You could probably get by with:
- Aoyue 937+ soldering iron [advertising link] ($59.99 from SRA [real link])
- Aoyue AOT-SI (also SRA) - you'll probably do better with this conical tip than a chisel / bevel [advertising link] type as those can lift the pads if you're not careful
- Thin 63/37 solder - if you decide to proceed with this and are in the US, let me know and I'll put a small piece in an envelope and mail it to you - you certainly don't need to buy a 1-pound spool
- Fine tip tweezers to position the capacitors - probably the smallest tip from the local drugstore will work
- Magnifier - I like the large one with a swivel arm and built-in lights, but it depends on how your vision is
- Something to hold the CPU - I use a hobby vise with grooved plastic jaws
