will we scrap meters because of this %@ of part ?   that's why i never bought theses series of meters because of that single part ....

i do  hope some substitution will be feasible

Hello

I am in process to try

Even as used a 2000 and some other Keithley cost $$$$ and use the 245 component and that sad or stupid to be force to scrap 600 USD or more measuring instruments IF there is a robust solution to repair

You have the option to buy a newer version that doesn't have the TF245, uses off-the-shelf arrays instead.

Hello

Yes but there is a lot of old models still in use and or need repair so rather to put them in the trask bin , I try to repair / upgrade

Take in consideration that other Keithley use also the 245 component not only the K2000 as the 2306 have the two TF-245 and 2010 also
In the 2010

the fact to use a bespoke connector with the 245 SMD foot print allow to install the patch on mostly all 2000 serie Keithley

Hello

Thanks , interesting
I have located that a SOIC header on which I can fit a socket to link my patch PCB by wire as I search / prefer to avoid stress on the main PCB but also be able to manage temperature / pcb stress of my in process patch

I link the ''quick and dirty first aluminium plate base on the CAD I have cut this day , patch pcb will not fit directly on this plate but on a SS304 plate with O ring to limit stress and dilatation effect

7 mm Holes net have been added to avoid to trap the heat of the microcontroller
