On a DSO138 9V pocket scope, I made a real mess trying to solder on/off the MCU. Not a good way to learn how to solder this stuff. I have the latest chip on there, pretty much lined up and soldered down with a lot better technique this time.
So now it has about 8-9 broken traces. So there are 1-3mm gaps I need to bridge. 2 I just added a few cm of wire back to the via's the traces started from.
I tried bridging the the 1-3mm gaps with a piece of lead from 1/8W resistors, and
-some are side by side so it's super hard not to end up with a solder bridge between them
-it's such a small piece of lead, it's always sticking more to the iron than the trace/pin, and so it always going out of alinement
So I gave up again. Now I have a Andonstar 301 microscope. And that's like shaving in the mirror, I'm not used to that at all yet.
So I could try adding more pieces of longer wire, tacking it on 1 end then back a few cm, I know I can do that, thats still hard tho, there's so little solder holding it on the chip.
I have a hot airgun too now, I never back when I 1st messed it all up. It have now idea if it's safe to use the microscope even at max distance with it, and so I really better not, I'm not risking that.
I don't have solder paste yet, it's on the way from China.
If I use solder wick on a 1-3mm piece of lead, I'm sure that will never work
Any advice is welcome.
