Poor manufacturing quality of new boards

ralphjy
ralphjy over 6 years ago

I received a new Raspberry Pi 3 A+ board from Newark/Element14 on Monday.

 

It arrived in a padded envelope instead of a box and the thin RPi box inside had been squashed.  This prompted me to do a quick inspection of the board and I was quite appalled by what I saw.

 

The first picture shows rework that was done on the board.  Very poorly done.  Solder reflow on the pads is bad and the solder flux and solder debris have not been cleaned off.

The second picture is of the GPIO connector.  The solder fillets are rough and you can see small balls of solder on the solder mask between pins.

 

I can't believe that this board would have passed final inspection.  The silk screen says Made in the UK.  I'm not sure where it was assembled.

 

Needless to say, I did not attempt to use this board.  I got an RMA to return it.

 

In an earlier discussion with ianbinnie, he indicated that he saw issues with his new RPi 3 A+ also.  Hope this is not an indication that there is a problem in the manufacturing line.  I have another board coming from Adafruit later this week.  I'll keep my fingers crossed.....

    I also found solder balls (only) near the through hole connector pins. I will clean them off myself. I can post a microscope video of the balls if it is useful...

    I’d be interested in seeing what your board looks like.  Solder balls are worrisome enough, but I am seeing solder tails on pins that almost bridge between pins in a couple of cases.  I’ll need to get some pictures.  I guess I ‘m just unlucky image.  Do you see flux spots on the board that look like someone has done rework near through hole pads?

    I only saw trace amounts of flux on one through hole pin.

    Here is a partial frame from the video showing some solder balls near the through hole joints:

    The video was shot with a $50 microscope/camera/display/recorder system.image

    Thanks Doug.  The two boards that I got are certainly worse than what you and Ian received.   But all are symptomatic of a manufacturing issue.

     

    I think that they must just be sample inspecting to some AQL level.  I would hate to think that the boards I received would have actually passed inspection.
