Title: Help with fixing a lifted pad?
Post by: Zombii on Sat, 18 March 2017, 20:51:24
Hey everyone, I'm not certain if this is the correct subforum or if 'Making Stuff Together' was a more appropriate fit, but this board is more active, so I thought I'd post here. If a mod feels like it should be moved, please feel free to do so!

While working on my LSv1 I accidentally lifted a few pads off some stubborn LED spots while swapping switches. I didn't realize this until I went back in to resolder the SIP sockets in the new switches to the board and found that a few of the pads were lifted. Does anyone have any advice on either jumping the LEDs so that they can still work, or soldering directly to the trace in order to get the LEDs working? I'd really like to try and get all my LEDs working as well as I can.

I don't have any photos at the moment, but I'll try to get some as soon as I can.

good god man

can either try and get solder deep into the hole or run a jump wire

i don't know enough about soldering to tell you how to do these things, but i've seen them mentioned as fixes for this problem before

Feels bad, the one switch on the entire board where the soldering is egregiously bad (due to the ****ty solder used by whoever put that specific switch in in the first place) and it's the one where I have a problem that requires me to post it :/

This board was the first time I've ever soldered something on my own, and other than that one switch, it actually looks pretty good besides some flux residue that I haven't cleaned up yet.

i mean i'd have the same reaction if i posted pics of my own soldering work

it works but it's not pretty

is this board traced on both sides or just 1 side.

I think it's traced on both sides

I'm looking at the front of the PCB using Photoeletric's picture  (https://geekhack.org/index.php?topic=53942.msg1206869#msg1206869)from this thread, try this

That's what I was thinking. My worries come from whether or not it it will cause any difference in the brightness of the LEDs. I would assume it wouldn't, since in theory you'd just be fixing the 'broken' connection as long as you weren't using a ridiculously thick wire.

It's late here right now, but I'll pick up some thin gauge wire tomorrow and try that fix, I need to get some more thin solder anyway.

It shouldn't..

but if you got a picture of the front of the pcb Nude... that'd help determine if it'll happen.
