Alright, according to the pictures the thermistor is going through the pcb hole. I will use Kaptontape to insulate the wires.Quote

On the Mendel90, Nophead epoxies it to the bottom of the PCB: [reprap.org] and then insulates the leads with teflon tubing and high temp tape.
But if i insulate each wire with kaptontape and then tape them with kapton tape the wires should be fine right?Quote

The thermistor won't melt at bed temperatures, but the wiring and insulation you choose could behave differently.
Alright so placing it in the hole to touch the glass and at the same time remove the glass after every print would not be a very good solution.Quote

You want the thermistor thermally connected to the bed so you get a consistent, representative temperature. Loose in the hole may give different readings based on the looseness of the gap, which is something you can prevent with a solid placement.

So you would recommend kaptontape it to the bottomside of the PCB, and not stick it through the hole? Sure I will get the temperature of the PCB bottomside but the glass top side will probably be about the same temperature right? (:
thanks again!
