Desoldering multi pin through hole components

[Marc]

Hi all,

My soldering is coming along nicely, put together a few kits etc and desoldered some small parts (caps resistors etc using wick).

How do you desolder things with many pins? Im not talking PGA here, but i'd like to work up that eventually. I've heard that solder suckers can damage PCBs/lift traces etc.

I have Solder/Hot air station/wick/IC suction tool/reverse grip tweezers

Am happy to purchase other equipment if needed

Hello my friend =)

Hokay - heres my setup -

An Aoyue Int 474A Solder Sucker

this is in combination with a Kada 825D+ Hot Air

Pros
with this combination it is able to remove the hardest / scaggest and oldest of solders

Cons
Its tricky to lern the combination of two devices at the same time - knowing the right temperature so that neither burn the board/pcb you are working on.

The Aoyue gun gets full quickly - infact on a job such as replacing a 72pin socket you will need to empty it at the end of it. Again this is experience here - most suggest to turn the unit off to remove the cartridge and then empty it - I dont.

I leave it on and hold the gun upright with the tip in the air.
Using a fabric heat mat I disengage the cartridge and then place it on the heat mat - this is so the solder falls to the back of the gun and not the shaft of the Tip (blocking it)

After a few moment I pull the cooling coil and the solder falls out in one big lump. I then load the cartidge back up and we are good to go again.


Extra Info
For delecate work I would recommend NOT to use spring loaded / pneumatic based suckers as the recoil from these can infact damage the board you are working on.

Spring loaded plastic tipped solder suckers are good for really only light work and the pneumatic suckers are.... well woefull in any degree I wouldn't recommend them.

ARGH more tools to buy!

Nice Lair btw!

just noticed when you do an image search for "Kada 852D+" - the fourth image is my workshop !!!!

Did you sell this unit?

I am still happy with the unit Zetro has, I am not a pro - but it helps for sure.

Did you already do real surface mounted components? I only tested on old mobo remove and put back on. My first atttemp gave a special mounted chip :|

 

[Marc]

I still have this unit, it's great for surface mount work, but through hole desoldering with many pins is causing me issues.

Heh, my limit on surface mounting has been removing/resoldering chips from old graphics cards/nics etc

 

[jvdbossc]

Yup me to - I just use the "air suck device" - the solder wick does not work for me.

If it does not come loose I flux and resolder and have another go - mostly it is done then.

I only did this on a few c64 mobo to fit sockets. Ask profs

Im really liking messing around with this stuff

 

[jvdbossc]

It is not my thing, but is nice to be able to do some basic stuff, like replacing a connector etc.. I must admit I use it as well to make longer cables

I made one out of a shop Vac when I was fixing my own stuff back in the day I hated the one you had to prime I took a small copper tubeing,cigar tube,steel wool and now let your mind run wild

I've worked with many electric solder-suckers over the years & for me, there's only one tool thats in a league of its own:
http://www.howardelectronics.com/den-on/sc7000.html

It has only one con: its price

But, its the best on the planet in what it does & also built like a tank.
I've seen these units work in labs where they are never turned off for years, without any service.

I'm considering buying one for a long time now but still cant justify the price for the amount of desoldering I do

 

[dabone]

I want one.....


But for occasional use, ouch! what a price. I just I'll stick with my click sucker and wick. (I had to beg work for months to shell out 100 for a hot air rework station, I don't think I could get them to spring for that.)

later,

@dabone,
Simple sucking pump operated by hand might do serious damage if operated incorrectly.

Yeah thats to much for me i'll just have to remake my shop vac to work with SMD now thats going to be tricky..

It looks more dangerous then expensive. I'll stick to my 5€ thumb powered sucker with silicone tip and good old Weller TCP. With this setup I never demaged a single board, and I've unslodered a lot of crap in my time.
