The connections are heated with a soldering iron until the solder melts and is wicked into the braid by capillary action.
The latter uses heat conduction from a probe heated to a glowing temperature by a direct current (much in the manner of a soldering iron).
To solder is to mend two things together with a soldering iron.
Ultrasonic soldering can be done with either a specialized soldering iron or a specialized solder pot.
Different equipment is usually required since a soldering iron can not achieve high enough temperatures for hard soldering or brazing.
Excess solder and unconsumed flux and residue is sometimes wiped from the soldering iron tip between joints.
The start-up only had a one-man research department, a second-hand soldering iron picked up for $25 and an outdated oscilloscope.
Special soldering iron and magnifying glass not required!
