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.

Subject: [TN] Connector pin protrusion


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?

Phil
