Maxim (was: Sockets)

[jorgen.bergfors at idg.se]

I use a carrier that has pins both top and bottom. The bottom pins goes in a normal IC socket and the top pins goes into a very small board that I have etched. The board is the same size as the carrier, which in turn is the same size as the IC socket. The small board has the copper on the upside, so it can easily be soldered to the top pins on the carrier.On the small board one or several surface mount parts can be soldered. I have used this for a dual transistor and a tempco resistor, all on an 8 pin carrier. The resulting module can be inserted and swapped like an ordinary IC. The carriers cost $1 each for quantities of ten.

If you use parts that are in 'lots' of other things, then
there will always be a few for the individual constructor.
For a manufacturer, the problem is entirely different.

I notice some people (like Aries) are making surface mount carrier boards with dip pins around them. If anyone sees a cheap source of these, let us know. Mouser has them at $5 or so.
(and for a mere $86, a universal zif soic to dip adaptor,
which I must admit would be handy for prototyping!)
