Looking for adhesive material to retain wiring

Threaded View
Have an HP laptop taken apart to replace screen.  During the takedown, I
encountered a number of places where wires are held in place with what looks
like a two sided tape product. It came off with only light effort, but not
too sticky after removal.  I would like to use such a product as I
reassemble.  Some concern as to heat resistence and would welcome any help
on sourcing such such material.

You don't say if you intend to dismantle the LCD panel assembly (to
replace the LCD panel or CCFLs) or if you're replacing the inverter
board or power supply.  The "screen" is the entire monitor.  It could
also refer to the LCD panel assembly (which still has several parts).
You need to be clear WHERE are these wires you're talking about.  Are
you just replacing a component or assembly (PSU, inverter, LCD assembly)
or are you prying apart the LCD assembly to work inside of that (CCFLs,
LCD panel, diffuser sheet, etc)?  You might just be opening the
monitor's case and looking inside to see the PSU, inverter, and LCD
assembly.  You might be looking at removing the LCD assembly to replace
a defective LCD panel or CCFLs inside.

It's probably butyl tape.

While I haven't dismantled and rebuilt an LCD monitor yet, I came close.
At the place where I was going to get the CCFLs and voltage inverter,
they provided a kit for all those parts that get destroyed when taking
the unit apart.  The kit included the double-stick rubber tape to hold
the wires and CCFLs in place along with solder and solder wick needed to
desolder and then solder in the new CCFLs.  There was also heat-shrink
tubing to put over the soldered ends of the CCFLs.  While double-sided
butyl tape might now be used to hold the wires in place, you might just
used single-sided strapping tape to hold them down.  I don't know how
the adhesive lasts for strapping tape but presumably you are using it
away from heated components.  I've seen Kapton tape also used (it's
expensive tape; see http://en.wikipedia.org/wiki/Kapton ) or something
that looked very much like it.

What kind of kit you get depends on what you intend to repair.  I was
going to replace the CCFLs inside the LCD panel assembly.  Because the
inverter gets stressed over time as the CCFLs go bad, there was little
point in putting in new CCFLs without also replacing the inverter board.
The CCFL repair kit did not include the strip of plastic sheet used to
cover the inverter board (so it wouldn't short against the assembly's
casing.  For that, if it didn't stick back on after removal, I might've
tried contact cement. At
, you
can see the inverter board at the top edge of the LCD panel assembly.
At http://www.lcdparts.net/Images/howto/TAB.jpg, you can see a pick of
it getting peeled off.

The kit came from the same place I would going to buy the CCFL
replacements (which were also brighter and better spectrum).  Since I
decided not to do the repair (because the inverter board was so
expensive that the CCFLs and inverter were close to half the cost of a
new LCD monitor), I don't have info on the site anymore where I was
going to get the parts.  I had taken the LCD monitor apart enough to get
the make and assembly number for the LCD panel so I could Google around
to find out who carried it.  I think one of the sites was
http://www.ccflwarehouse.com/ but don't remember if that's where I was
going to buy the CCFLs + repair kit.

If there is self-stick aluminum tape (for RF shielding), you can buy
that from a hardware store.  I think you'll find it in the AC/heating
venting area as it's used to seal the junctions of the duct work.
You could even use the aluminum tape to hold down the wires if you don't
need double-sided tape.

Thanks for the input.  Job is just an LCD panel replacement.  The two sided
tape retains the video cable lead and the wireless attenna leads.  I just
want to leave the machine as close to the conditions I found when I cracked
it open.  I'll check out the butyl tape.
