structural reliability of PCB mounting a SMT style RJ45 pcb receptacle

structural reliability of PCB mounting a SMT style RJ45 pcb receptacle

(OP)
thread820-398618: structural reliability of PCB mounting a SMT style RJ45 pcb receptacle
Following up on this RJ45 receptacle issue.
We knew that style with snap in pins cannot be used because they are incompatible with pick-&-place, so it had to be pure SMT.
Not too thrilled with our final choice so as we are now going to full production I will be closely watching for RMAs should they appear. We used pads as large as we could with vias to stabilize them and resist delamination. All pretty classical approaches. Using housing to constrain the connector body is not always & in our case, not an option due mostly to the housing cover being plastic and that it will deflect or shift before it will constrain the connector body!
Thanks for the interest.

RE: structural reliability of PCB mounting a SMT style RJ45 pcb receptacle

I suspect it will work OK, especially with your attention to large-as-possible pads.

Depends a lot on your users and the product. Sometimes users rarely use the USB connectors or the product gets plugged in only a few times over its lifetime.

I forgot about this option in my reply to your previous thread. Attached is a datasheet for some press in connectors. They require a separate press in operation and are therefore not compatible with pick and place processes but they don't require a separate soldering step either. These pins can take quite a lot of abuse, especially in shear.

That's got to be the most detailed connector data sheet I've ever seen. Amazing.

I like that the minimum board thickness has a tolerance.
