| Oct 13, 2023 at 21:19 | comment | added | dandavis | you don't have to get them all at once, one finger at a time works, as does copious solder. You can clean it up at the end with solder braid/wick, or just a stripped stranded copper wire, like you might use for speakers, to soak up an extra solder. | |
| Oct 13, 2023 at 13:50 | comment | added | onepo | @dandavis we're trying to solder to the surface mount pads right now and it's very difficult to get the heat on all the pads at once. we don't have a heat gun to hand so we might need to get/borrow one...? it doesn't help that it's been used because the pads seem damaged | |
| Oct 13, 2023 at 6:54 | comment | added | dandavis | you can use a regular iron to surface mount a microusb header, especially one that's already been used (pre-tinned). there's only 4 traces to connect, so even if damaged, you can follow them back and vampire to another exposed pad, like 5v from the voltage regulator for example. in fact, it doesn't even need to be on the PCB; keep the bodge wires short and manually run 4 24awg wires to the various connection points on the PCB and usb connector. that should last enough to re-upload. | |
