Over the past several years I've replaced ic's by clipping the legs and then using a desoldering iron to remove each leg. I've always been careful to avoid using too much heat or hanging around one area too long as you can lose alot of pads that way quite easily.
I guess wellers use magnetics and you can skip right past leg removal with heat and tweezers.
I'm just curious if others are doing it the same way or if there's a better method I'm not aware of. I use a Pace MBT-201. Just wondering if investing in thermotweez or something else works better for removing the entire chip intact or if that's even possible with the high heat limitations of these old boards.
Pictures, vids or links are welcomed.
 
Hakko 808. Seriously, get one right now.

I typically use a Weller WTCPT soldering station & vacuum desoldering tool but before attempting to desolder, I add fresh solder to every pin of the chip. This makes a big difference in removing the chip cleanly on the first pass. The other thing I do is clean the desoldering tool before using it to make sure its vacuum is at its strongest. This may sound a bit cumbersome but I have gotten fairly proficient at it over the years.

I have also used the clip each leg of the chip method but hate the cleanup however there are times where this is the best method given the board/chip combination.
 
Is this Hakko 808 vacuum supposed to outperform most desolder stations?? I mean it doesn't seem to be any superior to the MBT-201a as far as the solder extracting tool.
 
I simply desolder the legs with my Pace unit then take some duck bill pliers and give a little clockwise/counter-clockwise twist motion to the body of the chip to unstick any legs. After that the chip lifts right off the board, legs intact.

Very handy if you need to salvage chips for re-use.
 
I have one similar in design. You need to clean it regularly and use the silicon grease and it will work great. If you don't, the vacuum will leak where the collection piece joins the heating tube.

that thing looks like it will give you carpel tunnel after 30 minutes of use.

i am debating up upgrading my old station to a new hakko fm203 and fm2023d , just need to find a cheap source :)
 
... and use the silicon grease and it will work great. If you don't, the vacuum will leak where the collection piece joins the heating tube.

Do you mean "joins the suction tube"? Just trying to see if I can improve the suction on my desoldering station:

I really need to turn up the temp to see if I can get cleaner removal of devices from the board.

Be wary of the cheap desolder stations i have had one of these see link for a couple of months, used it about 30 times and already had to unblock it twice and now the vacumm wont lift the solder off of the board, i'm already saving for a pace as it has a larger heating element that receeds back down the tube to stop blockages.

Got one of these pieces of shit as well, absolutely useless...

Recently upgraded to a Hakko 472D, what a brilliant piece of equipment!
 
I have and had several pace machines. They don't like to be dropped when Hot. It's a quick way to kill the heater. They work great and for a long time.

Thanks for confirming they are a piece of poo and it's just not me hewie,i'm in the process of sending mine back to be fixed as soon as it comes back and it does actually work again i will flog it off on ebay for half price and tough it out with a manual one till i can afford a pace.

I use a pace MBT250 and its awesome. My last pace was 20+ years old. I used it for about 10 years and only replaced the heater once...when I first bought it. Replacment parts eventually got discontinued so I upgraded to the MBT250. It was worth every penny and easily paid for itself in 6 months.
The pace units are not for everyone since they are rather expensive. If you do a considerable amount of repair work I would reccomend spending the extra money. For occasional hobbyist use the cheap ones do the job and wont break the bank.
If you keep your eye out on ebay you can get some good deals on pace units. I ended up buying a second like new mbt250 for $300 just a few months after buying the first one so now I have a back up.
