I wonder, how do they rebuild the ribbon?
Looks like they don't and use a replacement; this would probably be the aftermarket item mentioned in the OP. Skip to 26:30 in the video and you'll see the process of transplanting the components from the old flex PCB onto a seemingly brand new replacement. A replacement like this would be fairly straightforward to recreate from an original in any PCB tracing software (e.g. KiCAD) and then order from a jobber like JLCPCB etc. It's of course time-consuming, so it's nice someone actually put the effort into doing this.
meticulous process
@chuckroast I understand very well what you say. I've watched the critical parts of the video. It doesn't change what I said about recreating such a flex PCB being a fairly straightforward process. This doesn't mean it's easy, or that anyone could to it, or that it doesn't require certain skills. But it's not rocket science, either.
Well, that's relative. The outcome seems to work, that's the important part. The soldering operations are rather crude.
there is some sort of low temp/cold solder scheme in use for that component that he could not figure out how to remove/replace.
We're not quite there yet. Single digit nanometers isalready pretty darn small, though.subnanonmeter chip lithography
Oh, I did not mean to suggest otherwise.I judged the price to be worth it to have someone do it who does so regularly.
Interesting conversation. Thanks. Yes, a question is if this replacement lessens the chance of failure, or is simply a reset to start a new failure cycle of similar duration.
Any idea if this outfit deals with other cameras? The Fuji GF670 is known for both being a nice camera and for making a nice brick from electronic failure.
Thank you for sharing your experience. I am about to ship out my 645zi for this repair to the same shop in Poland.
Be sure to get their input first on how to package and mark the contents. If you do it wrong, you get clobbered with outrageous Polish tariffs.
Thank you. I've been in contact with them and they sent directions of how to label the camera. Do you recall how long the repair took and if they addressed any other issues for you?
As I recall, end-to-end time was something like 5 weeks once I got it posted.
I had no other work done.
I just shot with mine last week and it works just great.
