S19J Pro hashboard repair question: clear plastic insulator film under heatsink?

[omkarasystems]

Hi everyone, potential silly question for the repair techs here.

I'm reworking a big stack of S19J Pro boards, and I can't seem to source the clear insulator film that surrounds the ASICs underneath the heatsinks anywhere. And I can't seem to avoid destroying the existing material during the troubleshooting process.

What are you all doing when you reinstall the heatsink after reworking a board? Kapton tape? Rawdogging the heatsink on there and hoping the ASICs are proud enough to avoid shorting the rails? Or is there a source for these insulators that I am missing?

Thanks!
