What causes solder not to stick?

A classic reason solder won’t stick to something is because you’re not getting it hot enough. My interns come to me with this problem all the time. Make sure the tip of the iron is nice and shiny. Touch some solder on it, and it should melt almost instantly.

Can you soft solder without flux?

Good solder joints simply do not result from working without flux. At low heat the solder might not melt fast enough, and a cold solder joint may result. At high heat the soldering tip may oxidize and that will make soldering almost, if not downright impossible!

Why is it better to use soldering paste flux when soldering?

While the main use of solder paste flux is in the creation of solder paste, it is also sold directly as a gel or tacky flux. Solder paste flux can also act as a temporary adhesive. Its tacky nature holds components together until the heat of the soldering process melts the solder and the parts are fused together.

Why does my solder ball up?

When soldering silver and using hard or soft solder, I often find the solder balls up – it just refuses to jump no matter how long it’s under the flame. This is because the flux has burnt out and there is no medium through which the solder will jump (or run as some would say).

Can you solder two pieces of metal together?

But you can join them by melting them together in a process known as welding. The basic idea is simple: you apply a source of heat to melt the two metals so they fuse and form a secure joint.

Is flux the same as solder?

What is Flux and What is the Difference Between Flux and Solder? While solder is used to assemble components onto your circuit board, the flux is used prior to assembly to prepare and help your board through the soldering process.
