GPIO Pins not seated properly

Wed Nov 13, 2019 6:18 pm

I ordered a Pi 3 Model B+ through Amazon, it arrived with the pins placed one position off and not fully seated. Anybody seen something like this before? Pics attached

That should not have escaped from the factory.

Keep it! Someone will pay good money for a unique Pi variant. :lol:
Clearly faulty at manufacture, as drgeoff says it should not be out alone in the big wide world. :(
Or someone has done a good job at faking a fault :o

Irony is I got it to use with a Google Coral for a vision system to inspect plastic parts.... I'm thinking the pi factory might need one of the systems. The circle of life..

The engineers will want to see the QR code sticker on the back, so post a picture of that before you return it.

Did the heatsinks come pre-applied? If so, then you may have received a used/returned product (no Pi model includes heatsinks). :?
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?

That type of error should be pretty easy to catch with automated inspection, even a simple dimension check would have failed with the header sticking up that far.

Interesting.

Wouldn't one have to work quite hard to jamb a header in like that. One might have expected the pick and place machine would have a panic trying to do it.

Looks like something someone picked out of a waste bin at the Sony manufacturing plant, and sold on e-bay.

This sometimes happens when a tray in the wave solder machine does "bump", its a production fault, and should never pass the testing phase (it probably doesn't even fit in the tester).
Because its not economically feasible to repair its usually just discarded.

Every Pi goes through automated optical inspection at each stage of the soldering process. There's no way that this got through those.

@mike14mile: Please post a high res image of the small sticker on the underside of the board (it has a QR code on it). Also, if you can get it to boot, please post the full output from cat /proc/cpuinfo for the serial number.

If I got my hands on a Pi in a state like that I'd either try and fix it and then give it to a local school or charity (making clear that it was a repair with no guarantee), or if it couldn't be fixed but still boots, I'd try to use it myself.

So couple things:
- the pi runs and boots fine. I've tested the camera with it, wrote a quick python program testing the pin outs and have it recording pics and videos on a button push :)
- I applied the heat sinks when it arrived before I noticed the misplaced headers. This is the 3rd pi I've got, and the packaging seemed normal. Small white box with the logo and instruction sheet. It is the first one I've got through Amazon (first 2 were through canakit). The seller did offer to return it, but... I kind of like it :)
- the serial number from cpuinfo: 0000000005279555 , revision a020d3, hardware BCM2835
- attached picture of the qr code on the back

It's really intriguing to me, as a person who works in manufacturing, so whatever theories you guys have or ideas keep 'em coming.

Any news? Interested in if you were able to find any history on the board. Thanks

jdb,

Given the pristine nature of all the soldering on all those header pins I'm inclined to think the unthinkable may actually have happened.

It does have a test record, therefore traceability - so somehow it managed to get through all of the inspection steps (and auto-tester) after wave soldering.

Sony's QA department is investigating.

Thanks for the update... appreciate it. If they want it back for inspection I should be able to free it up early next week. Thanks

that unit "could fetch" a good price , more than the original price of the RPi itself :mrgreen:
