suicidal_orange 100 Posted April 24, 2022 Share Posted April 24, 2022 Looking at USB-C connectors the surface mount ones seem to have 15 pins, you have 12 pins and 3 holes. Usually the surface mount soldering tabs stick out the back though (so they can be soldered) while you had to melt the plastic. The through hole connectors have 12 pins but no gap so if it's one of them it's weird... Do your pins go through the PCB or not? Quote Link to post Share on other sites

I don't know if there are additional pins under the connector (which solution also exists but in different layout). So yes, it has twelve visible pins. Anyway, by looking at Type-C connector pinout: It practically only has 12 pins. The only difference between these two rows are SBU1/SBU2 and CC1/CC2 but these are the same connectors for different cable orientations. However, I don't know what pins are used for HDMI alternative mode. I have found another drawing: Theoretically TX1/RX1 and TX2/RX2 may address different USB ports but I would not think it is connected to different USB port at hardware side... So, practically it seems to only has 12 different connections. Quote Link to post Share on other sites
theory 15 Posted April 25, 2022 Share Posted April 25, 2022 If you go look at the available PC board mount jacks, every one I have found actually brings all 24 pins out to the PC board individually... And I've looked at about 30 so far... To actually run at full 'C' speeds, the TX1/RX1 and TX2/RX2 sets have to go to different pins on the chip that runs the interface. BTW, the pictures shown on Mouser, Digi-Key and other supply houses are often generic... You usually have to dig into the data sheet to find the actual pin spacing and layout... -- 1 Quote Link to post Share on other sites

Yes, basically connectors provide all pins at board side. 5 hours ago, theory said: To actually run at full 'C' speeds, the TX1/RX1 and TX2/RX2 sets have to go to different pins on the chip that runs the interface. I haven't designed USB3 connections yet (microcontrollers I use have USB2 interfaces) but if I look at USB3 pinouts, it looks like this: So it has a USB2 data pair and additional RX/TX data pairs. (These are differential wires, so RX- and RX+, also TX- and TX+ belong together and TX provides transmit and RX provides receive direction.) So for USB3 connection, it has three wire pairs altogether. I wrote above it may be connected to a second transmitter/receiver and I don't know how display connection works, so, for example, if HDMI alternative mode uses these additional pins or what happens. Also, there are special connectors like a Type-C which only has 6 pins and provides USB2 interface but not USB3 at all, so other connectors with reduced pins may also be available. 5 hours ago, theory said: BTW, the pictures shown on Mouser, Digi-Key and other supply houses are often generic... You usually have to dig into the data sheet to find the actual pin spacing and layout... Right, that is why it is not easy to find the right connector, especially if it is not a general connector (all connections wired to board). Quote Link to post Share on other sites

True - missing pins (soldering pads) are a common problem of mechanically disconnected solderings. It may still happen that second row had released solderings for me although I do not see it is mechanically moving or at least not the outer case of my connector. These are very thin wires and soldering pads so there is a high chance if connection releases, then soldering pad will break. Also there is a chance for damaging soldering pads during the removal of connector as if soldering was not melted at all wires when connector was removed, that will easily tear off the soldering pad itself. It was much easier to re-wire missing soldering pads of mechanically broken micro USB connectors anyway as it had much fewer pins. 🙂 Quote Link to post Share on other sites

Sometime are pads too smashed and is impossible to make bypass for all missing pins...then is solution made bypass only for data and charging. On removing...use around 330celsius and head connector from top...it must be really fully released. If is near microphone, then cover it with kapton tape and if mic have hole on another mobo side then cover this hole too...mic can be smashed really quickly with hot air! ...then remove all old tin from holes for connector frame.Put new tin on all pads(same amount - not too much), put on it really small amount of solder flux (i use warton smd rework jelly). Now it is littlebit tricky...put connector into cleaned holes, fix board AND heat it with hotair from another side - heat it through board - and only with 250C...and wait - connector must "sit down". Finally solder connector frame with classic soldering station. Thats all.. Simple 🙂 ....sorry my english is not good for long stories 🙂 Edited April 25, 2022 by CornholioGSM 2 1 Quote Link to post Share on other sites

Right, it has too many and really small connections... Anyway, one older connector which I did not like is the wide USB3.0 microB connector. Simply because it was much easier to tear off together with pads and it also has some additional electrical connections... I really hope pads underneath my connector are still intact and removal of connector will be successful. 🙂 Quote Link to post Share on other sites

This. I recall they designed the Pro1 specifically to have the USB port on a dedicated board (and thus easily replaceable) as the USB socket was a well-known weak point of the N900 (where it was directly soldered to the mainboard). But without spare parts, that design effort was futile at best ... 2 1 Quote Link to post Share on other sites
Kaali 76 Posted April 27, 2022 Share Posted April 27, 2022 I had the exact same charging problems and only the cable connectincg the usb board to the main board was loose, the connector is shown in your picture.

pebert 98 Posted June 29, 2022 Share Posted June 29, 2022 was more thinking that it´s a more relaiable source with a MOLEX connector that you can buy in a lot of different places, with short delivery lead time. I will order some from Mouser to test with. Looked a the USB-PCB from my crashed phone, if I could reuse that PCB to prepare it for a fast swap. But that PCB is quite bent, so I doubt it will work. //Per 2 Quote Link to post Share on other sites
Tomatoman29 11 Posted July 11, 2022 Share Posted July 11, 2022 (edited) Hi people, I am a Pro1 user for over a two years right now and I broke my USB socket. So if I am reading this and other topics correctly, the biggest advantage of this phone became its biggest mistake and fxtec does not only even have replacement part to be bought to fix own Pro1 but also does not responding to the emails, am I right? How screwed I am? There is any chance to buy the USB socket assembly? I sent an email to fxtec but if they are not even responding then I have no Idea what to do.

They can take two weeks to answer. It could be longer with the current efforts to push out the Pro1x. They may have the spare part since ordering parts for the Pro1x allowed them to get some extra inventory of parts that are identical for the Pro1 and Pro1x (and I believe this is one of them). I assume when you emailed that you got a robo-acknowledgement at least. If not, you may have not succeeded in reaching them. Others here can be of more help in sourcing the part yourself, but give FxTec a little extra time. 1 Quote Link to post Share on other sites

Rob. S. 1,649 Posted July 11, 2022 Share Posted July 11, 2022 Just for the record, I've been in contact again lately with Fxtec asking whether there was anything to be done with regard to my USB connector and my screen, for which I'd prefer an original replacement because of the margins problem. Of course I'd want the screen only if I can get the USB fixed, too. They came back quickly informing me that displays were currently available; then they wanted me to confirm whether I meant the device's USB socket, which I did. It's been a few days since then, but let's see what comes out of it. 2 Quote Link to post Share on other sites
Bob78 0 Posted January 5, 2023 Share Posted January 5, 2023 Bit more on mine It has now got to the point that it will only charge under plug tension. in other words I have to place a weight on the charge cable and pull the phone away against the weight .It then charges quite reliably. No way to work long term any cure spring to mind ? It has to be a phisical fault. 1 Quote Link to post Share on other sites

EskeRahn 5,433 Posted January 5, 2023 Share Posted January 5, 2023 Odd that they did not have those as a spare part on IGG. Be aware that that the port is NOT at the same position in the frame for pro1 and proX (sits higher on the X), so MIGHT be different pcb as well. Quote Link to post Share on other sites
