Hello
In process core swap, here's picture, Q: where I put plus lead ?
I know that spring is minus and core is positve, but where is positve in pcb ?
This module was originally crappy ebay laser: 2xAAA wow 150mW--NOT as U know... ( today I just tried pot mod from 380mA--670mA @ 3,2V and it survived :D! now 420mA@3,2V and inside 100mW label...yes ebay rules....NOT)

The positive should be the entire metal module casing.

Edit: Nevermind, I saw that you were asking for the PCB. I would not know.

Look at the laser diode pins. One will be connected to the case directly ans two will have insulating beads where they enter the case. Follow the pin that is connected to the case directly to the PCB and that is your positive trace.
