We have to perform a wire modification on a PCB. I am looking for a wire where the insulationmaterial does not shrink or melt when soldered.

I bet ya box of Krisp Kremes our operators can melt insulation on wire better and faster that yours can!!! Aww, our operators can melt any insulation on any wire. It�s taken years of effort to develop the talent, but not matter what we bring in for them to try, they melt it. Teflon is generally thought to be a high temperature tolerant insulation, but they can still melt it. [That stuff�s for whooses.] Yano, sometimes we wonder if may be the trick is managing our process so that the operators remove the iron and stop soldering before the insulation melts. Coo, eh? ;-)

Ooo, ooo. I got it!!!! This is too coo!!!! Use bare wire and shrink tubing. Then when you burn the shrink tubing, it�ll shrink and you�ll be ahead of the game and not have to use your hair drier. ;-)

Er, use enameled wire ... can't say I've ever seen anyone melt that stuff.

OK. OK, I�ll stop. Here, look at: http://www.circuittechctr.com/guides/6-1.htm [Thanks to Denny Ferry and Circuit Technology Center, Inc. 45 Research Drive, Haverhill, MA 01832 978-374-5000 � Fax: 978-372-5700 for posting this great repair guide.]

I know this isn't what yer asking about, but this stuff is so coo [http://www.intertronics.co.uk/products/cpreleg.htm]. We just screw a U shaped tip on the iron and go!!!

Dear Dave.

Thanks a lot for your reply. The link to the guidebook is very interesting.

Thanks Anders.

To expand on that, the melting stuff does work quite well with us if we intend to melt the insulation but luckily our "solder slaves" want to be proud of their work and manage to not melt even the worst material they are confronted with. I somehow managed that they regard their work as "artwork".

The other side of the coin is that they see themselves as artists and think their work is worth a lot more than they get paid. While seeing the "artwork" of other places I think they should get a reward but that�s not in my responsibility. In my case it�s not a question of process managing but more a question of poeple managing.

Can�t believe that it�s that bad in your place, Dave, you are kidding aren�t ya? Or is it that the prophet isn�t heard at the own site ?

Circuittech�s site helped a lot in getting my slaves on the right track, should have thought about putting this link up myself.

Giving my "slaves" the wire Dave mentioned was a great step towards good results and good mood of the "slaves". Don�t be afraid of the $$, it sure pays back.

...and what did I learn? Doing my work well helps others to do their work well (I still have to work on that one when there�s some spare time ).

Have a great time all

Wolfgang

Ah Wolfgang, just too much time in hand-to-hand combat. * If more than 5 percent of our troop where that way, they�d put out of business. * If my troop [even the boneheads] caught me disin them, I�d get: skunk-eye, dressed-down, told-off, and who know what?

We use 30 and 32 gauge PTFE wire. The insulation will not melt with normal hand soldering temps. The wire was made by Thermax/CDT. Their phone number is 800-423-5873. The only problem with the wire is that is hard to glue to the board. We use TackPac from Loctite or RTV.

What kind of volume do you have to do? If you are doing a large quantity of boards, there is one other solution. There are a couple of companies out there, Additive Services Inc. and Conductive Circuits, that can actually take your boards and add a trace instead of adding a wire. Both of them have web sites, http://www.additive.com and http://www. conductivecircuits.com. For large volumes, they can save you a lot of labor and quality headaches.
