No. You will overheat or burn the PCB. This is how *NOT* to do it:

Personally, I prefer to use a hot air desoldering stations with an
aluminum foil barrier to protect nearby components. Lots of flux. A
solder sucker might tear the traces off the PCB. Tin all the
connections before soldering. Use alcohol to clean off the flux.

I can't tell which one is appropriate for you. Micro USB connectors
come in very different configurations.

Note: I destroyed a few connectors and ruined a cell phone before I
learned how to do it properly. Find some old PCB's and practice.

Went looking for some spiral cable wrap to build a few simple
wiring harnesses. ISTR it was pennies per foot some years ago,
so I expected dimes per foot now.

Turns out it's dollars per foot for the spiral stuff, but slit
corrugated hose is much cheaper, roughly what I expected for spiral.

Anybody have a clue why? The convoluted material looks a lot
slower to make. I tend to think it's inferior mechanically,
and certainly is bulkier.

Thanks for reading, and any ideas...

> About 40+ years ago I was a Plastic Extrusion Operator and also worked
in the R&D Department. I was involved in the design and setup of the
rotating blade that cut the 3/8" poly tubing. It had a variable speed
drive that was used to adjust the number of cut rotations per foot of
the tube. There was a lot of small adjustments that were made to get
with the =/- tolerance to meet the customers specification. I still
have some of the scraps laying somewhere. When I have a need I use
about 6" or 12" to hold some wires in place.
(you can't use it if you throw it away) :-)

As for your question of cost............... Sorry, but I don't know.
I would have to guess it has something to do with supply and demand!!

Hope the above helped with someone's knowledge base!! :-)

Depends on whether it needs to be an approved or listed component
in a certifiable wiring assembly.

Anybody can slit extruded tubing. Materials certified for flammability
or chemical/thermal/mechanical properties in a specific application
are harder to devellop and to market.

You have to specify the wiring materials - why should the wrap be
excluded from this stringency?

Temu sells similar stuff for $1.98 delivered.

I've found this really helpful for a lot of our rack building projects:

https://www.wirecare.com/category/conduit/spiral-wrap

They have a very wide variety available.

My initial search was aimed at local retailers.
In the end I found what I was looking for on Amazon.
but it took a couple months to assemble a $35 order....

The product you located looks similar, I agree it's
extremely useful.
