00:01 <Joerg-Neo900> using soldering iron you'll need a very slim tip and yet you gonna have to cut and remove some metal sheets to get by

00:03 <Joerg-Neo900> or the hacker approach: use 0.1mm diameter varnished copper wires maybe 6mm long, to connect USB jack pins to PCB pads, then *carefully fold the wires back to place the USB jack into place and solder it down mechanically

03:25 <Oksana> Dissipate all heat, to where? Don't want to burn something fragile like camera module...

03:41 <DocScrutinizer05> Oksana: you ideally remove the cam module prior to USB fix. Or at very least cover it with e.g. Kapton tape. The groundplane whare you solder the jack shroud to will not heat up so much that it could damage other nearby components. That#s actually the cause of the problem that it spreads the heat and thus reduces it to levels that are harmless for components but not suitable for soldering a proper joint

03:43 <DocScrutinizer05> you need a soldering iron that has sufficient thermal mass or power to heat up the soldering joint within less than a second so the heat doesn't spread much into the surrounding area

03:48 <DocScrutinizer05> several folks done USBfix before break and it's really simple and low risk, you just need a decent literally heavy soldering iron. Or e.g a Ersa Analog-60 (sufficient Watts, the "60" here is err whats the opposite of exaggeration ?) which did the job great for me

03:51 <DocScrutinizer05> :nod:

03:55 <DocScrutinizer05> eeew

03:55 <DocScrutinizer05> green rust is actually a massive issue. You know skin effect?

03:56 <DocScrutinizer05> there's a reason to have antennas rather silver/gold plated than green rust

03:58 <DocScrutinizer05> thanks to skin effect all but surface and maybe a few micrometers deep into conductor from surface doesn't matter at all - high frequency RF current only flows on the conductor's surface

03:59 <DocScrutinizer05> iirc it's caused by eddy currents and the magnetic fields they create

04:01 <DocScrutinizer05> but if I had to guess, I'd suspect any problems you encounter with this antenna are first and foremost caused by contact failure at the point where the C-spring touches the antenna conductor

04:02 <DocScrutinizer05> when the antenna builds up green rust, the chances are it also builds up oxides and other "dirt" at that point between antenna pad and C-spring

04:02 <DocScrutinizer05> somebody (in here?) had exactly same problem a few days ago

04:03 <DocScrutinizer05> whoever you been, could you please report back opn results of your "fix"? :-)

04:03 <DocScrutinizer05> on*

08:17 <sicelo> Oksana: it definitely is possible. obviously one must be careful. i watched some youtube videos before doing it

18:06 <DocScrutinizer05> ZombieLoad yay
