SMD-to-DIL adaptors

These adaptor boards are designed for readers who find it increasingly difficult to experiment with certain integrated circuits which are only available as SMDS (surface mount devices). Also, an increasing number of ICs is no Ionger manufactured in DIL shape, being replaced by SMDS (for example, the 74LS163A). Obviously, the problems are caused by the small size ofthese parts, which require dexterity, as weIl as by the fact that SMDS do not sit in sockets, and thus are not easily removed from a circuit for a quick test, or for faultfinding.
