I will check out the laquer when i get home. I cant remember where its from.

So, i cant put normal laquer on the PCB before soldering. Is it fine to do it if somehow it doesn touch any of the pads?

Ive always been told never to file a soldering iron because it wont work properly. Something about the heat not being focused to the point or something. Ive not seen anywhere that sels the kind of tips the old one uses. I could do with a new really expensive one from Rapid that will work well.

If you cant put it down the drain then where does it go?

I dont have any Surface Mount Devices but i do put components on the underside of the PCB to save space sometimes

I tin a board by fluxing the traces and melting a very little bit of solder on before I place the part. The are other ways though.
Traces? Should that have been "tracks"? Do you mean you flux the whole thing but only put a bit of solder on the pad or do you put solder on the whole thing too?
