tripwire 139 Posted August 18, 2015 Share Posted August 18, 2015 Does anyone here find kapton tape useful for holding things in place on PCBs or protecting against shorts? If so, what size tape do you prefer: narrow ~10mm wide or big 50mm rolls that you can snip smaller pieces off? Quote Link to post Share on other sites

If there is a large price difference, go for the 10mm. That tape is going to last a long time. tripwire 1 Quote Link to post Share on other sites

That tape is going to last a long time. I'm expecting the 50mm roll to be better value for money (ie less than 5x the cost of a 10mm roll). That said, you do make a good point about how long it will take to use up. I've still got about 24.3 metres of a 50mm x 25m double-sided tape roll that I'll struggle to get through in an average lifetime Quote Link to post Share on other sites
jpnorair 340 Posted August 19, 2015 Share Posted August 19, 2015 Kapton (polyimide) has high resistance to chemicals, and it can take a lot of heat without melting. It is sort-of default for copper etched films and things that are exposed to chemicals and/or heat, but imidized plastics are quite pricey. If you can find polyester/PET/mylar tape, you'll probably get a better deal and, practically, no worse performance. tripwire and bluehash 2 Quote Link to post Share on other sites
