"Side-brazed".
However, when the leads break off or fall off due to corrosion, at least
you can (relatively) easily come up with a replacement. When the leads
break off of a DIP with a normal lead frame, it often is right at or
even inside the point that the lead exits the package body, and is much
more difficult to replace. Through carelessness with a logic analyzer
probe I accidentally broke off a lead from an ASIC in an old system, and
there was no way to get a replacement other than to buy another used
machine. A friend surprised me by succeeding at repairing it with
conductive epoxy.
