Just a thought Marcel,
For 'soldering' of SOP / TSOP etc. it is actually rather easy to use a normal iron along with copper de-solder braid. The key is FLUX. You cant really use too much flux, and, you always need to use flux...
You can 'tin' the pads by wiping them with the iron (with flux added first). Then add MORE FLUX and use the de-solder braid to remove the excess and clear the gaps between the pads (far far easier than it sounds.)
Then add flux to the pad area and place the IC on the pads in the correct position. Use a small screwdriver or similar to gently press the IC and hold it in position. Then add FLUX to the pins and tin the iron and dab and wipe along the pads / pins either side. Dont worry at all if you get solder bridges. Ensure that the position is maintained by the gentle press from the screwdriver or similar.
Then simply add MORE FLUX !!! - important !!!. (you see a pattern here haha
). Now add more flux and use the de-solder braid again to remove and pin bridges.
Then use isopropyl alcohol to remove the flux with a toothbrush with a gentle action and check with a multi-meter for any hidden bridges.
Tips, always use LEADED solder - never use 'lead free' . Get a reasonable quality flux. you can get it in syringes etc for pennies. -
I have up to date fluxes, but I also have a tin of plumbers rosin flux that is nearly as old as me ! - seriously , it from about 1965 (it was my Dad's!).... I still use it... but, don't use 'modern' plumbers flux as it contains acids... but that's an aside.
You can also use a similar process but with a hot air rework gun.
I cant find my model anymore as it is quite old, but there are similar ones about. You don't need to spend a lot of money at all on a decent temperature controlled gun. Mine was around 100 dollars, but, I found this one on AliX that looks like it would do the job nicely and is from the same manufacturer.

You can always play as the stuff is so cheap (chips / boards etc etc) It takes less time to do it than to explain it. The iron method can be just as good as the hot air rework method. I often just use the iron, flux and solder wick / braid.. If I happen to move the chip on the pads, I then use the rework gun to heat up and gently move the chip.
The chips can withstand an amazing amount of heat (for short periods !) and I haven't destroyed any chip (yet) from heat.
If removing a chip, the ALWAYS use hot air re-work gun - no matter what some dubious you tube sites say. You can get a heat resistant miniature sucker to hold the chip, then simply heat around the pins until the chip moves a little then lift off with the sucker. *the sucker / pickup is also pennies -

A HUGE mistake that people make (don't ask me how I know
) is to use a very fine soldering bit for this kind of work. This is simply not needed and can be detrimental, a 'normal' standard bit as fine as you ARE going to bridge the pins with an iron, just dont worry as the de-solder wick / brain will sort it. A VERY fine tip is only great for working on a specific pin or tiny area - ie - to add a link wire etc, but not for this kind of use.
As an example, my main soldering station is an OKI MFR1100 (you probably dont want to know the price
) - I also have a LIDL cheap and nasty iron that was about 15 Euro.... I often use the LIDL iron more than the OKI unless I am doing board modification. Go figure..
. the LIDL does the SMD job superbly with it's standard bit(s) .. just add LOADS OF FLUX, and LEADED (tin/lead) solder. and solder wick / braid.... flux flux flux and solder wick...
you will be fine. you can be a bit of an animal and then 99% of the time sort it out after it is attached with braid and flux.
I tend to use an illuminated fluorescent ring lamp lens unit - the ones with the adjustable arm - quite cheap and about 3 or 4 times magnification. 'Blue tack' is used quite often to stick the board to the bench haha.
I find those 'helping hands' etc only of limited use.
Give it a go ! . you will be amazed at how easy it is.
