Good Afternoon, In reviewing PTH connectors it looks like the standard pin length (for the through board connection) is double the board thickness. 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?
