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.

Back in my discrete days I used copper eyelets for connecting large
gauge high current wires.

The military balk because the solder _under_ the eyelet can't be
inspected.

Ultrasonics or X-rays won't work?
