Hello to all,
I have rencently developed this pcb board for LM4780 and would like to know some recomendations for the insulator.
I haven't seen a ceramic pad for flexiwatt 27 does any know where I can source good insulators for Flexiwatt 27, I
would have interest also in mica/plastic insulator.
By the way I will supply this board kitt together alongside with my other modules that you could check here:

Or reach me through here.
Regards

Your best bet is to find a sheet of SilPad or similar thermal pad and cut it to size. That's what I ended up doing for the Parallel-86, which used the LM4780. Make sure the thermal pad covers the entire back. Otherwise you risk cracking the chip when you tighten the mounting screws. Ask me how I know... 🙄 I also found a spring clip to be the best mounting method. Aavid MAX08 worked well.

For who is interested in this module now it's available on my page but I am still looking for solutions or recomendations
I would like to know if some user can advise what kind of insulator or part number is used in popular 4 channel
amplifiers like TDA7850 which use the same package, mostly used in automobile car radios or they all use it's
tab connected to ground chassis.
