Hi Adrian, I have your picture posted, it is here: http://stevezeva.homestead.com/PCB_Slot.jpg That certainly is unusual, I don't think you'll find anything in IPC that addresses that sort of interconnection. But the important thing is whether or not that works for YOU. Personally, I don't see why it shouldn't provided that there is a continuous fillet that wets completely to the pin and walls of the slot. It looks like there is a void in the fillet that you have circled in red, I don't think you want to see that. One other thing that you might consider, although it's had to tell from the picture, it looks like those pins might be gold plated, I think I would consider removing the gold so that there is no possibility of embrittlement issues. Interesting connection scheme though...
