Lately, all I've seen in 0.100" prototyping

phenolic material in small sizes from China with nearly unusable pad

chancy at best.
I used to be able to get fairly good-sized (6"x10") pieces of FR4
protoboard with useful patterns (e.g. laid out for 0.300" DIP, with
power traces down the middle and pads extending for 2 holes from each
DIP pin) with all holes being plated-through.
Short of taking old PC ISA or S-100 prototyping boards and cutting
them up, does anyone know of some good sources for proto boards?
It really is a sad state of affairs. I know the Chinese boards
you're talking about...I don't know what those guys were smoking when
they came up with some of those pad layouts.
I've been reduced to just using the Radio Shack pad-per-hole
prototyping boards. Their pad adhesion isn't that great, but that
has made me more careful. :)
