Alternatives to precise soldering - conductive plastic?

[medved]

Hi

I wanted to ask, is there a way to connect electrical components without soldering.
A silver paint for pcb trace correctures is easy to get - but can it be dosed precisely and will it hold the components on pcb?
What about the conductive plastics - is it possible tu buy it somewhere, and is it conductive enough?

Here is webpage that mentions condutive plastics(Polyaniline, Polyethylenedioxythiophene) (the site is about organic LEDs, by the way, is ti possible to get these light emitting plastic too?)

Why? Soldering is easy, durable and inexpensive.

a quick Google search for "electrically conductive epoxy +soldering" turns up
http://www.sra-solder.com/epoxies.htm
I think the best way to dispense would be with some sort of syringe.
Read Carefully some epoxys for electronic work are THERMAL Bonding type for
attaching heatsinks to chips, while they do have some metal in the content
they are not intended to be highly electrically conductive, actually quite the
opposite so as to prevent shorting.

H500: I thought the same thing until I thought about someone trying to solder something to paper, plastic or perhaps a hydrogen filled balloon - strange ideas but these are strange times......

Soldering to a hydrogen filled balloon. . .

Perhaps using a propane torch ?
Way Cool, I want to watch . . . from very far away.
Got any video?

solder it dude.......if you have mass projects and looking for short cuts......contact volenteer circuits in bells tennessee....pcb manfacturers and wave solders
