I was just looking how to make a solution for cooling ...how to attach heatsink to hypex amp. modules and I have turned them upside-down.
Then I noticed that some things look like soldered by hand...
I mean , boards are obviously soldered by machine but on some contacts there are traces of flux...
So I'm interested is this level of manufacturing quality normal for hypex?
Is it a custom for them to re solder something if the module have some higher spec. tolerance or something?

If it's on a single board but not others, probably a board that was repaired after manufacture. If it's consistent across several boards, it's probably a hand-soldered part.
There's a few possible reasons for hand soldering - the pins are quite close to nearby SMT which means they probably couldn't use a selective soldering machine. Or the part that was hand soldered isn't washable. Or for some reason the parts weren't available during manufacturing, so they built the rest of the product and stuffed the extra part when it arrived.
No problem if it's no-clean flux.

It's a single board. Other one is perfect!
As I wanted this for not so cheap speakers , I must admit I was a bit worried to turn it on. I don't mind the "cosmetics" / the look of solder marks and traces of flux but It did make me wonder about quality of that work.
Anyway , I contacted the manufacturer and it turns out they don't consider this as normal quality of their work so they have apologized. And they have offered to make a replacement if I'm uncomfortable using that board.
They have really nice support service!

In their webshop they show 2 pictures of this amp. If you compare them, and look at the parts also resoldered on your pcb, the biggest heatsinked parts in both webshop pictures show a difference that might need resoldering on their webshop top picture too.
