Hello,

I am looking for a good way to mount a daughter board to a motherboard that can be ~~hot~~ swappable. I would like it to be able to mount securely preferably with mechanical clips or fixings.

There will be up to 10A to go through it for power as well as around 10 signal pins. Obviously I can use several pins to get the required current rating.

I have seen DIN 41612 connectors but I am concerned about the daughter board coming loose.

If anyone can help me it would be much appreciated ๐Ÿ˜Š

Ermmm.... If you use several pins to get the current rating, what happens if one of the pins fails or gets corroded? Won't you risk generating heat? Think I'd prefer nice big connectors for the power and to keep the data lines safely segregated. Depends on your needs and design I suppose.

You get the same problem with big connectors. I have seen many large connectors corrode and melt as a result of the bad connection.
