What it amounts to is soldering the "front" of the SIMM to one edge of the
pins and soldering the reverse side to the other. if the edge of the SIMM
is appropriately close to the pin-strip, it makes a very solid connection,
with the loading stresses well distributed.
It doesn't stagger anything. These screw-machine single-pin sockets come in
plastic strips which keep them aligned. The way I accomplish this sort of
thing is plug them into a board which fits their barrel and proceed to
solder the connections, end pins first, on each side of the SIMM until the
job is finished. It's a lot of work, and not always worth it. I once
soldered 4 4MB SIMMs into this arrangement, only to learn that the
motherboard I was using wouldn't deal with the 4 MB parts. . . . too bad .
