Tape used for securing wires to PCBA?
« on: March 30, 2021, 07:29:58 pm »
I'm working on a prosumer AV product design -- actually something already in production, but doing some design revisions.  I'd like to make assembly a bit easier by giving the assembly techs some kind of tape that can be used to hold some fan and antenna wires in place and out of the way.  Having taken apart various consumer electronics before, I've seen some sort of flexible, fabric-backed tape used for this purpose -- often for things like antenna leads in laptops and such -- but I have no idea what kind of tape it is.  Something like Kapton would probably work, but it seems like a fabric-backed tape might offer more flexibility and easier installation.  I have to imagine 3M's giant product list has something specifically for this, but I haven't found it.... Anyone know what kind of tape I'm talking about, or have a suggestion on something that might work?  Thanks!

Cloth tape. TESA make a black cloth tape (51608) - I've seen it called fleece tape also.

Sounds useful to me too for taping up wiring harnesses.

Googling TESA 51608, I get a number of references to 3M 1755.  But while the 3M 1755 says harness bundling on the datasheet, it also says that it is a cloth backing which is covered with rubberized adhesive on BOTH sides.  So I think this is a fundamentally different tape. 

(The TESA 51608 looks great... it just isn't stocked by any of the distributors my purchasing department has accounts with...)

Its coated on both sides, but only sticks to itself.

Thanks -- Tesa is a manufacturer I wasn't familiar with, and it looks like they have lots of niche products, good company to know.  Too bad it's hard to find distributors for some of their stuff, I guess they mostly sell direct to large OEMs.  Anyway, found a place selling 51608 and ordering a roll to try.

Basically, Tesa is the 3M of adhesive tape in Europe. It’s omnipresent, and in many European languages, people say the equivalent of “tesa tape” where Americans say “scotch tape”.
