i will still try to fix it, i would give up on it but surely i would come back to try and see if i can fix it
i posted the photo, i remember it was very small and it had like a green mark on it (near ALC chip)
there is the photo that i posted above, i have to take a photo of the BQ IC. i also bought, while writing this, a microscope from amazon, it will be delivered tomorrow.
i’m sorry i made a mistake.
Sorry I can’t make out the component your talking about from the photos, if you can circle it in paint or other I can let you know what it is supposed to be.
K, when your microscope shows up try getting a photo of the joints round the edge of both ICs so we can see if that’s where your issues lie as it’s not possible to tell from an overhead shots atm
Try measuring the voltage at either side of the fuse with battery and USB connected
Ah I’m blind yeah it’s a no stuff - those pads are are connected to each other on all my boards.
getting ready for tomorrow, i have the feeling that i totally wasted money
@Severence @Insomniac The 20€ that i spent on this microscope would be the worse in my life, i cannot take a photo of an entire chip, and the res is somewhat acceptable
NOT AS EXPECTED
I’m sorry but this microscope is absolutely dogs**t
It’s probably the stand that is the issue more than the scope. When I was using the cheep scope I ended up using my helping-hand to hold it, as it could be held higher up. You could also just put it on top of a book or something. Once it is further away you should be able to adjust the focus.
I assume you have one of these? :
For these particular shots you could also hold it to get a nice side-on angle so we can see if there is a gap between the board and the chip, and if the solder is connecting to the side of the pin or only under the chip.
yeah i do have this one.
ok, trying it rn
nope, still out of focus.
Just got my old one out, holding it wasn’t great, ended up doing this and then flipping the final image:
Agree,
Also the board is still too caked in flux it’s impossible to see whats going on and all you’ll get is misleading reflections as a result, heat the areas with your hot air at 140C while mopping up with cotton swab and IPA, clean, rinse and repeart - continue the process untill the board is as clean as Insomniacs example board, and as he says take the photos with the IC’s on an angle as currently I can’t tell if certain areas are stray solder or fluff
Taking this picture… I may have just found the issue with my board though it may just be flux.
Haha, I saw that but thought this might be a donor
that’s the problem and an easy fix
That one was labelled “Working, but charges one way”… I guess its worth putting together for a test. But that’s one for another thread
HAHAHAH would be hilarious!!!
