Comment on Raspberry Pi cuts product returns by 50% by changing up its pin soldering

The main problem was that it interrupted the line. We’d have to stop and inspect each product, then reposition or replace the connectors, before the reflow oven. It also ran the risk of damaging the connector, the PCB, or even the inserter head if the insertion force was too high. We had a higher rework and scrap rate compared to similar SMD-only products, but using pin in paste meant that wave soldering could be skipped altogether, and I guess someone above my pay grade determined that it was better in terms of finances.
This is just my own experience. I don’t know Rpi manufacturing practices.

That’s some interesting insight - thanks 👍
I’ve done some sm work but as repairs and upgrades … it definitely was /easier/ to remove and replace: that was for sure. I’m unclear on if it ultimately had a higher real world failure rate though.
Personally I’m hopeful that their reasoning for this is increasing the quality of what does hit shelves even if there is a higher on line failure rate. They can’t always be the cheapest (and recently haven’t been) but if they can double down on “It just works” for a slightly higher price… I’m here for it and I imagine other makers likely will be as well.
