Almost all of our drawings call for soldering to J-STD. (MAX pin height over PWB is 0.060") This is for connector patterns only. Other PTH components are installed with the same criteria, even though it is not required. This is just so we have one standard for our operators to follow.

For an 0.062 board the pins are 0.120" long and for a 0.090 board the pins are 0.180" long. We have some connectors that have 0.130" long pins that we want to use in an 0.090" thick board. I maintain this shorter pin will be problematic to solder reliably. Am I on the right track?
