Probs with Duo2
 

Hi Guys! Got a real problem with my duo 2 chip :(

So i got i v10 mashine, an i´ve downloaded the diagramm for it. Now on it says that I´ve got to solder also on the backside! There are little ring-like "solderpoints"! And my problem is, that i cannot solder on the backside, i do it like the other ones, but it will not fix?! How can I solve this problem?

Thx 4 every Help!

Edit: Here´s the Diagramm for it (Problem with #6!)

LOL, the tiny VIA's on the back can be little tricky. Be sure you carefully scrape all the laquer off the points and use flux. Once the wires are stuck use a Q-tip to clean any excess flux.

I must say, I do follow shadows' tips, however I do use flux - it makes things much easier (I know he doesn't)
