1/ the TSOP56 is surface mounted
2/ i cannot find a TSOP test clip (Pomona, or otherwise)
3/ I dont have the pad space to install a socket
4/ suggestions so for are
- solder on magnet wire
- use micro-grabber (purchased, not arrived)

Q1: Is there a mechanical way... clip on, or over, sockets that has surface mount footprint to be able to probe any pin at any time

Q2: Im thinking about putting leads on a similar chip and mechanically pressing it on top of the existing chip ( with a big C-clamp) providing the rpessure

Q3: Is there another way, per chance,

A1: https://www.360-clip.com/
A2: won't the "similar chip" interfere with the one you want to debug?
A3: remove the chip from the pcb, analyze it, the put it back on the pcb - it sure is another way, but this would be my last resort only.

A1. What about test points on the PCB?. No connector required.
