robin_x, I find it difficult to solder small components as my eyesight is not as good as it was and I don't have very good equipment. The 2nd link from hastelloy says "use like any other glue" there are hundreds of types of glue all with different properties and requirements. I want to solder (or glue) some output connectors onto something I am making but do not want to damage the components in the process.
Thanks for the link to the video which is interesting. I have a magnifying lamp and even a microscope. I have repaired a monitor by replacing capacitors and resoldered an input power jack on a tablet sucessfully but is a bodge job in my opinion, a pro would laugh at it but it worked.
I don't have the bits I need yet so dont know how difficult to do, my main concern is that some components have internal plastics which can be destroyed by too much heat.
My original question was seeking an easy alternative to soldering, if not then I will have to solder them.
