Abstract
A hot bar apparatus for effecting solder bonds for high density electronic components has a diamond or diamond-like (i.e. a generally diamond crystal lattice with graphite impurities) surface that makes contact with the leads of the electronic component and transmits the heat necessary to effect a solder bond. The diamond or diamond-like surface has superior wear characteristics over any other material, and it also is an electrical insulator to protect the electronic components from spurious voltages and currents generated by electrical currents that provide the heat for the hot bar.
