ES9023 / WM8804 S/PDIF "Subbu DAC V3" GB Interest

[houghtkj]

Personally, I use a 2mm chisel bit for ALL my SMD work and have had no problems. If you use too fine a tip, it's very difficult to keep the tip tinned which means it's harder to get a thermal contact with the part.

So I would go for a B005360 bit - And don't forget the solder wick!

I think 5360 is that I have now

BTW what about solder wick (I have one ) ?

Just need to make sure the tip is clean and well tinned - I use a damp sponge and that course wire wool stuff.

Life just isn't complete without solder wick - I use 2 widths for SMD - 1.5mm and 2.5mm. When soldering something like the WM8804, I find the best method is to flood solder the pins, then wick off the excess, which should also get rid of any bridges. Be VERY careful not to let the wick "freeze" to the chip pins or pads - Just keep the solder molten and the wick moving.

You will almost certainly want some additional flux - I use a gel flux and apply it with a syringe - Use plenty because the flux in cored solder burns off quickly.

Good luck - Ken

Thank you.
Off topic: been de soldering trimming pot , and somehow ring on pcb around wiper is not visible any more.
I have checked continuity between wiper and adjacent pole and it is there (as on the rest of pots) and not sure is pcb damaged or continuity is there for a reason
Any ideas ?
P.S. Hate desoldering ...

I like the copper Chore Boy as it is a bit coarser an is well - copper
They are available at most grocery stores and I just stuff them in an old spray paint can top.

Good idea this scrubber bcmbob

Hi Ivan, Bit of a problem there - Is the PCB double sided? And which pad has lifted - Solder side or component side? If it's the component side pad thats lifted, you should be OK assuming the through plating is good. If it's the solder side, you will need to scrape and tin the trace and piece out with a short bit of wire.
Hope that makes sense.

It is Uriah's Lighter note. It is the solder side. No pads were lifted its just the black ring surrounding wiper got missing.
I ll try to scrap , otherwise order replacement pcb. Only few components been soldered so damage is not that big... the learning curve !
