This Sams Photofact (founded
in 1946) advertisement from a 1962 issue of Radio-Electronics magazine
is a good example of why the company's electronics product service packets were
so highly regarded. A couple other competitors came and went in the decades of the
twentieth century, but Sams kept on because of their reputation. In fact,
Sams Technical Publishing is
still in business today! By 1962, the electronics industry was in the beginning
stages of transitioning from vacuum tube amplifiers and rectifiers to solid state
equivalents, and from point-to-point wiring to printed circuits. The illustrations
created by Sams artists for point-to-point component hookups were very high quality
(as were the ones created by
Popular Electronics magazine), and as can be seen here, those for printed
circuits were equally good. One and two sided printed circuit boards (PCBs) were
the rule in the day, and sweeping curvy trace lines with big round soldering pads
were used - partly because they were easy to create, and because the absence of
sharp points eliminated peeling points. The adhesion of the metal foil to the PCB
substrate material was not all that great, and a combination of excessive heat and
pressure applied to the traces during the soldering process (using a soldering iron
or gun) routinely caused separation. Trace repair kits were always on-hand
for repairmen and hobbyists building a kit.
BTW, if you happen to know anything about the "PEET" program mentioned at the
bottom of the page, please let me know. I cannot find information about it anywhere.
