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.
