Edge Plating does not have a set definition per IPC. However, the industry generally accepts this as being copper plating that continues from the top and bottom surfaces and along one or more perimeter edges. Edge Plating can be used for a variety of

You should see a coarse silverish / grayish coat on the termination that indicates that it soldered. We have to opinion [don't know] about the strength of solder connection versus the strength of component terminations.

If you think you have an intermetallic, soldering as probably done correctly. In that case, expect the solder to fail in the solder, just above the intermetallic. This the weakest portion of the solder, because the tin has be depleted to form the i

Today's consumer electronic product are characterized by miniatuization, portability and light weight with high performance, especially for 3G mobile products. In the future more fine pitch CSPs (0.4mm) component will be required. However, the product reliability has been a big challenge with the fine pitch CSP. Firstly, the fine pitch CSPs are with smaller solder balls of 0.25mm diameter or even smaller. The small solder ball and pad size do weaken the solder connection and the adhesion of the pad and substrate, thus the pad will peel off easily from the PCB substrate. In addition, miniature solder joint reduce the strength during mechanical vibration, thermal shock, fatigue failure, etc. Secondly, applying sufficient solder paste evenly on the small pad of the CSP is difficult because stencil opening is only 0.25mm or less. This issue can be solved using the high end type of stencil such as Electroforming which will increase the cost.
This video demonstrated the use of BEST Inc HotDots(TM) which allow wires to be affixed to the PCB or other surfaces-even when those surfaces go through reflow. There are other similar products out there but none of which can be readily customized no
