So, Im going to attempt to gain mod my DMIC-20 as per dr.ph0b's instructions: http://www.taperssection.com/yabbse/index.php?topic=23659.0 and Im a little nervous... I don't think that it is above my skill level, but I've never soldered to a circuit board before, so I have some questions... Specificly, does anyone have any advice. Im kind of afraid to drop some on the board. Im assuming to de-solder you just heat it up and suck it up ASAP. How do you solder to the board. Thanks so much for any help you can give me!!!

Swampy, Get yourself a nice large table mounted magnifying lens. less solder the better and try not to keep the heat near the board for too long. Are you soldering wires or resistors or caps or what?

don't fuck it up, r00kie :P
i wish i had something of substance to post, but oh well. it's fun just to mock you ;)
SWAMPY PAYS FOR GAY SEX!!!

Thanks for the help ass :P ;D
-
good luck bud, i wanted to do this awhile back like i was telling ya saturday but everything was on backorder :P
just keep patient and relax, and dont get too much solder in your face
and like has been said, dont keep heat on the board too long
-
ya, Im just gonna make sure I go REEEEEEALLLLLLL SLOOOOOWWWWWWW

you sound just like a girl i used to date :P ;)
good luck, hippie :P
-
may i suggest getting some flux. it'll make the solder stick to the board better. and use the finest point tip in your soldering iron.
-
like a girl sucking chrome off a tailpipe, soldering braid will suck the molten lead from the circuit board.
it takes a bit of practice, but it's quite easy once you get the hang of it.
good luck, swampy.

FIND AN OLD PCB BOARD AND PRACTICE ON IT
can't stress that enough, try to recreate the final solder on the old board
-
I would reccomend desoldering braid as opposed to the sucker pump style things, it works much better and is fun tio use as well.
Good Luck, watch out for cold solder points.

Okay, so Im doing okay so far. Ive got the wires soldered to the pots, and the oldd 2 internal gain pots removed. But now on the board where the holes are, I cant get the holes clear of solder... See in this pic, hes got 6 nice little holes, how can I do that? Ive tried the solder sucker, any suggestions? (http://www.routeflap.net/dmic-mod/PICT0037.jpg)

wipe the tip of your soldering iron clean w/ some newsprint and then lightly heat up one of the ~holes. rinse repeat. This is assuming you don't have a de-soldering bulb or air/vacuum soldering iron.

In the absence of an old PCB, go to Radio shack and buy a handfull of cheap assorted parts and a project board. For about $10 you can practice soldering/desoldering for many hours without risking your gear on your first try.
And get your self some flux cleaner.
-
the braid will take care of that alex, it gets everything really clean
also, keep a wet towel/sponge around to wipe the tip of the soldering iron off and keep it hot as hell
-
Yeah, agree with Bean here, run to the shack and grab some braid. Then place the braid on top of the solder point, apply heat, and watch as the solder completely soaks in and disappears. This will leave you with an empty, nice looking hole from which to work.
FWIW, I found 4 percent silver solder to work better for pcb stuff. Just what I found though.

d, shoot me your damn addy, we need to exchange a few tapes :)

In my experience, braid works OK if you have a relatively hot and large tip on your iron. You can buy braid impregnated with flux, or just the raw copper braid. If you are new to this, you probably want the flux-impregnated braid.
One tip I recently came across (after being involved in electronics, one form or another, for 20 years!) is thus:
Have a hard work surface to hand. Apply heat to the solder for a few seconds... and when it is good and molten, quickly slip the iron to the side and BANG the board down HARD on the work surface. Provided there is a small gap between board and work surface, the solder will splodge out. This does actually work very well, a fairly clean solder removal, no flux required.
I normally do this on PCBs I designed though... so even though my career is in electronics, I would be VERY wary of doing this with anyone elses boards. G-forces can fuck up many crystals, you have been warned!
best regards,
stephen

ive done that stephen,m even when no hard surface is around, i just snap my wrist and it usually goes flying out
especially useful when doing 3/4-pins ;)

paint thinner is also a great flux cleaner
