If you happen to have the Solder Paste Height Measurement System, it would able to do the works for you. That's only if the leads are not long.

Dave, May I ask where did you find the 1.5%, or the goal of .005" (or .007") per inch? The IPC-A-600 bow and twist standard calls for a .75% based on the calculation of the test method TM-650, method 2.4.22, which calculates the percentage based on
