Fish Paper or modern replacement?

[mike_mccue]

Can anyone recommend some good choices for a easy to source material that I can use as an insulation sheet underneath a eyelet style circuit board on stand offs such as found in old Fender amps?

Are there any new materials that don't warp or distort after a few decades or is fish paper still a best choice?


Thanks.


best regards,
mike

Kapton B has a dielectric withstand of 2600V/mil - 10x better than vulcanized paper but $$$

Why not thin PCB stock with no copper on it? Or phenolic board? They make very thin glass-epoxy boards as the layers for multilayer PCBs. One of those should be just about immortal.

Edit: just looked, and Electronic Goldmine has "scissors cut" copper clad in 12x12 sheets for $5.00. It's 0.010" thick. It'll be a little bit of a PITA but that could be cleaned and tossed into an etch tank and get you 0.010" thick glass-epoxy.

I'd pay good money to know how you linked to a specific page on McMaster's website. I usually give people part number or tell them what to search for. Mind sharing your secret?

Right click the McMaster link above. Now go to "Properties".
There you will see the http link to the specific McMaster web page.
If you typed this into your address bar, that is where it will take you.
Now double left click the link above.
After McMaster's page loads, go up to the address bar.
Go to the full right part, beyond the address & left click the address bar & hold down the left click.
Drag the cursor across the address in the bar.
It will turn blue.
Release the left click & it will stay blue.
Now right click the "blue address".
Go down to "Copy".
Now you have to "paste" it somewhere.
Whew!

I'm either hallucinating or McMaster didn't used to be that way. It was a frames website (it just displayed mcmaster.com in the address bar, you couldn't right click a link and open in new tab, etc.) and trying to get a link to a product was something I never figured out. Either way, thank you for the explanation, because now it made me look at the site again and see that their URL structure changed.

When I'm on the page I want someone to find I just copy the URL from the web address bar and past it into the newsgroup editor. In the old days the exact address would be displayed in the posted message. Now the newsgroup SW changes the link display to a short form of its own choosing.
Enjoy,
Tom
