I have always done initial checks right after I have finished my soldering/casework without any adverse effects. And of course, the β22 was a different story, I took forever and great care with that one.

I instaled already the off-line settings too, I see there Gamma2, but when I start to play music from foobar, there is shown that USB Audio DAC is unavaible, what´s that ?

Thanks to both of you, I'll begin SMD stuff tomorrow hopefully and see whether or not I get carried away and marathon the whole board out. Friday I'll endeavor to get some Isopropyl and give it a clean.

you can wait months.

in fact, I just did. finally bought some 99% iso alc. (kept forgetting to get this but been meaning to). the made-for specialty can spray removers work very well but are $15 a can! drug store alc. is cheap and I finally tried it. works very well (I rinse the whole board under hot water and then air-dry with compressed canned air so that no water is left on the board, even under chip legs).

the board looks brand new, now. and it had been 'fluxed up' for half a year, now

Yes, I can add it like you show me, but then when I want click to play, nothing happen, song don´t start

How long do you let it air-dry before applying power. I have wanted to wash the boards as you describe but with smd devices I am just a little worried about trapped water. I guess if you use compressed air and let it sit for a day it should be fine.

I used a hairdryer after dousing in alcohol. Not the best combo, but I got very clean boards and burnt fingers as a result.

As for Wizik, let's see a screenshot of your output devices (where you choose DS, ASIO, etc). Also take a screenshot of your ASIO4All window. You have used ASIO4All before, right? Do you have the foo_out_asio.dll in your components folder?

sit for a day? you kidding me?

I spray it with canned air and its dry right then and there! if you LEAVE any water there, THAT is the problem. better to get it dry in the first 5 minutes, if you can.

I also avoid putting trimmer pots on the board if I'm going to alc/water clean it. same for screw terminals and things where there is metal to metal.

one of my first jobs, as a kid, was working at a hand-built pc board shop (early 80's). our *standard procedure* was to use acid flux (some liquid red stuff), do board touch-up (first process was a wave solder conveyor) and you had BETTER scrub off acid flux or it will eat thru things. we used soap and hot water and a scrub brush. just like a kitchen sink (similar setup). we had a drain rack (didn't use canned air back then) and once the boards were dry, we did some test and then shipped them onto the next manuf stage. it blew me away seeing circuit boards being washed and dried like dishes in a sink but apparently it worked for that guy, back then. and the boards were nice and clean when we were done with them.

after that, I got over my fear of water and circuit boards. just dry them well but its not hard to do nor should it take a long time.

I can't understand why you would use water at all

My cleaning regime is a soft toothbrush and >99% isopropanol, with very gentle scrubbing. I keep it 'wet' with isopropanol to make sure everything stays dissolved, and slowly increase the amount that I splash on with the toothbrush. Excess is gently shaken off, I wipe everything down gently with a Kimpwipe, then air dry a few minutes. If there is still a white residue, I re-wash with more isopropanol.

Isopropanol has a much lower evaporation temperature than water, and will dry off very quickly in air. It is relatively non-conductive, and sufficiently pure stuff has low levels of salt contaminants that will absorb water from the air further down the track. Drying water is much more likely to leave stuff behind IMHO, unless you have access to really good double de-ionised stuff.

I was never able to get all the residue off the board with just alcohol. but a hot stream of running water made quick work of it once the alc. loosened the debris.

as long as I shoot a lot of canned air at things, the result looks good enough to me.

Yeah my method is basically what Beefy does and I have never been able to get ALL the residue off and usually just say F@#$ it after a few washes, no will see it and I doubt I will have this part long enough for any problems to arise.

 

[Beefy]

The secret is making sure things stay dissolved - a tip I got from TomB. Don't just slap some on and let it dry, but make sure it stays 'wet' with isopropanol. Rinse a lot once everything is dissolved, then get as much excess off before it dries.

Here is screenshot, everything looks OK, but when I click on play, nothing happens.

My y2 is connected via optical and Iam using usb input from my pc for power, but when I connect usb Iam getting noise, bearly audioable but its anoying between tracks.
Would using this help; Emerson Network Power | Power Supplies | Power Supplies, Inverters, DC/DC Converters & Generators | External Power Supplies | Switch Mode - Emerson |DCH3-050UK-0001 , as I wouldnt be relying on my pc for power source, or any other better powersupply options?
thanks
