Soldering

Joining metal parts using a low-melting-point filler metal called solder, without melting the parent metals.

Welding, brazing and soldering use heat; riveting holds parts together with a fastener. Their differences matter because a method suitable for an electrical connection may be unsuitable for a heavily loaded frame.

A process that melts a filler metal called solder to join metal surfaces, providing an electrical connection and mechanical attachment.

Distinguish the parent metal from the filler metal. Welding melts the parent metal at the joint; brazing and soldering do not.

PCB population means adding components, not creating the copper tracks. For through-hole assembly, explain both drilling and soldering.

When describing soldering, state that both the copper pad and component lead are heated, and solder is applied to the joint.

A joining process in which a low-melting-point filler metal melts and bonds metal surfaces while the joined parts remain solid.

Riveting, adhesive bonding and soldering are examples. Removal may still be possible, but it usually destroys a fastener or breaks a bond and requires the joint to be remade.

Joining metals using a molten filler with a lower melting point than the metals being joined, without melting those base metals.
