crt monitor tape

scroeffie1984 · Mar 8, 2021

any one know what the name of the tape is i was cleaning my commodore monitor with a compressor and 3 pieces of yellow kind of tape came loose !
its holding copper wire
see video

< i have the same monitor time stamp 5:00 you see the yellow tape on the copper wires on mine 3 came loose ,what kind of tape is that its holding a thin 1 copper wire down

It is not going to be anything special -- thin bit of tape is mostly there for assembly and maybe minor heat-warm cycles to prevent wear on the enamel on the coil wires where it overlaps and goes off to the field control circuits. No prevention of conduction or induction or anything will be done by it.

Bog standard electrical tape will probably do (though likely not be that long before heat gets to it) but if you have it then maybe consider some kapton (the orangey/brown clear stuff you have likely seen all over the place, including in many windings) as it should handle heat a bit better, or maybe some transformer winding tape as it will also be designed to handle a bit of heat. If you are buying one in then go with kapton as it has loads of uses more than the transformer stuff.

I am not sure what it would have been back in the day. Might be too early for aramid but there were also some fairly decent paper tapes.

Isn't that the same tape they us in fixing like, when you repair a broken screen or touch sensor on an android phone?

the tape is like paper kind of tape or the kind of tape they use in medical stuff ,but the tape is holding 1 thin copper wire not shure wy ?
wil by capton tape wil post a pic of the tape

each piece of tape is holding 1 or 2 copper wires not shure why

Looks like the tape back in the days for Speakers. Remember them? Try going that route in finding that tape. exact same, I swear it

i dont think electrical tape is good to use in this case because of heat over time the glue under the electric tape gets like jell-o

the tape reminds me of medical kind of tape almost like paper tape ? its been there for over 30 years so it must be somekind of special tape

What they probably found was during assembly, shipping, handling and whatnot if they had the handlers yanking wires, moving them around to get in and out and to the boards controlling the deflection coils that they were getting either fatigue cracks or wear on the wires in/out join the main body of the coil (it is certainly where 99% of electric drills will fail, what usually fails on any wire I have to fix, why you have strain relief going into tools...) caused a lot of their trouble.

Put a bit of tape there and you prevent the wires from flapping in the breeze and getting snagged on things, change the location of the stress point to the edge of the tape, possibly have it so you know the one under the tape goes there and the one over goes there, possibly where things expand as you heat it up (deflection coils are not as fun as electron guns but they take a pounding never the less) and end up shorting out a few turns (or maybe a lot of turns).
You also get the added bonus that you can probably salvage a coil if it breaks at the tape bit rather than as it vanishes inside the coil proper by soldering or crimping a replacement length on there.

so basically put a new piece of tape over the old piece of tape

I still say the tape they used in speakers.
