Was it just one bad via on one board, or a whole bad batch? Philco
had a factory in Mexico that had lots of problems with consumer
electronics, and Delco made a MAJOR design mistake when they used
"Griplets" instead of plated through holes in a series of car radios.

What makes eyelets or griplets so much less reliable? Expansion? I don't
see a reason why they should break more than a connection to a lead does.

Of course they have the disadvantage of only connecting outer layers.
