With press-fit HASL is the best and with an alternate finish like ISN or IAG the PTH size need to be re-evaluated for the new finish.

Also, is immersion white tin the preferred finish for press-fit, or is immersion silver or something else? Thank you in advance. Kaye Clayo Sr. P. C. Layout Designer Keithley Instruments, Inc.
