He is trying to remove the chip. He said he said ti needed to be followed
with a PTFE sheet (i.e. Non solderable follower) And in his first post he
talked about not destroying the traces on the board while removing the chip.

OT: Heating Windows To Reduce Condensation During Winter

2009-11-22T02:40:13Z

I've got a bit of a problem. Its now winter here in Japan and my heater
works great... But My windows are single pane and condensating like crazy.
Anyhow, I'm looking for some kind of heating for these windows.. Possible
carbon track heating like on the rear windows of cars. I know the proper
solution is to have a proper insulated doube pane window, but this place is

It does. Like most every other element, lead reacts with other stuff in
the environment to form salts, acids, etc., so while elemental lead
itself may not be a huge environmental problem, these compounds can very
easily contaminate water and soil.

I am a believer in aggressive government regulation. Really. But...
I also believe there is no such thing as a hazardous substance -- it is how
materials are used and disposed of that makes them hazardous -- or not.
Lead is a poison, and a nasty one. We know that. The question is really what
happes to the lead in the solder when the item is disposed. I'm still not

Let me guess... as the wire went past a ball of solder, it melted the

If that's true, a non-solderable follower will certainly cure that
problem.

esselte or dymo labelmanager 9000

Hello,
When I power up my labelmanager, I can see "k"'s on the display. The
labelmanager does not react for any key but the Symbols and Specials
ones and no other actions are possible. When Caps is on, "K"'s appear
on the display. I have also controlled a possible shorted k-key but no
problem. I also verified the soldering of the cms chips but nothing

I just tried some 0.4mm diam nichrome wire under an Intel BGA, but yes it
would probably need following up with some Kaptan or PTFE sheet slid in
after.

No, or rather not that I know of. The wire would need to be VERY thin
