Default Kind advice required for desoldering ?

Hi,

i am desoldering parts with tiny leads on a unit with tiny traces
I am using a desoldering pump with mechanic action and i do not like it
What do you use ?
I am not looking for a complete desoldering station, that i would love by the way
Just a decent and not very expensive desoldering device
In this operation i risked to destroy some units ... it is even more delicate than soldering
Kind advice will be very much appreciated
Kind regards, gino

Are you trying to rescue the components or repair a PCB ?

Hi and thanks for the kind reply
I watched a video on youtube about this ... i did not like it
I like something like a real electric pump ... something very fast, very pro and very cheap
Ok .. i could make an effort for something very nice
I intend to desolder a real lot
Only for this preamp i have there are tenths of parts to be replaced
New caps, diodes ... and the traces are very delicate
Kind regards, gino

Hi i am actually replacing 20 years old parts in a preamp with new and supposedly better components
They are very tiny diodes (1N4007 ... someone told me that they are not the best around and i have already bought UF4007 to replace them all)
and electrolytic caps ... about 20 years old
I am still undecided between Panasonic FC and Nichicon Gold as possible options for new caps.
I hope that at the end of the process the supply voltage would be less noisy
and the overall sound more transparent
Thanks a lot. Kind regards, gino

So you are trying to repair a PCB.

Best way is to chop the component leaving long legs in the PCB. Then heat each leg and pull it out. This will be easier than trying to pull out the entire component.

Caps are a bit more tricky but I stay with the philosophy - f**k the component, save the board.

Braid every time for me. And a hot iron with a large tip that can carry the heat.

Working with SMD. How to do it without specialised tools.

If you are using braid it needs to be fresh. Tarnished braid is useless.

Can't say I've ever had a problem with braid tarnishing (as it should be heavily fluxed anyway which prevents tarnish). I'm still using stock I obtained over 15 years ago (Servisol brand) and its fine.

I suppose it depends on the quality of it. I always end up cleaning it and applying fresh flux to get it to work. Flux will eventually tarnish the copper braid.
