I would like to know if there is any technical literature that talks about the difference in the reliability of a single sided no plated through hole solder joints compared to a double sided plated through hole. I really will appreciate if you can indicate to me any technical reference that describes such comparison between these to solder joint geometry, and specifies parameters such as strength, life time of the joint, etc. Actually, more than a plated through hole, I am taking about what could be called a "plated through slot" versus a single sided no plated through slot, making the solder joint with a "metal wrap" or what could be considered a metal piece surrounding an RF circuitry.
