Hello,
Newbie question  :
I already have some solder rolls 
- 0.7mm sn/cu
- 1mm sn/cu/ag 3%

So for my brand new cp5176, what should I use :
1 - sn/cu is ok, no stress man...
2 - even if 1mm is pretty big you should use the sn/cu/ag because ag makes the difference
3 - you’re a fool, you need to buy some 0.7 (or 0.5) mm  sn/cu/ag or you gonna fail
4 - emergency stop ! if you’re not using 3.4% ag you’ll be curse for 3 generations

Is the solder brand matter ? 
What should be the iron temperature ? (Or range of)

Thanks
Nico

Both are OK but I prefer leaded solder for ease and reliability.
Choose "No clean" solder if you can.

[Nico]

Thanks for the quick answer.
As a non professionnal customer, I can’t buy unclean stuff anymore...
So I have to choose between my list... the best I can at least...

"No clean" solder is available for unleaded as well.
It means that the flux inside the solder is not corrosive and it doesn't need to be cleaned.

Arrrrf, I didn’t get it... so I ordered some Sn62Pb36Ag2... with flux CR2......crap !

From what I can see via Google, CR2 is a "No clean" flux.

Well I looked the datasheet (en français), and I may have to clean it.
