SMD-to-DIP Adapter: Pin Soldering “Fixture”

I needed a rail-to-rail op amp in a DIP package to breadboard the amplifier for those toroids and came up dry, so I sawed out a protoboard square, glued a MAX4330 in SOT23-5 atop it in classic dead-bug style, rearranged the leads into the standard DIP pinout, and moved on:

The trick to getting the header pins aligned is to stick ’em in a pile of perfboards, which instantly makes them stand up straight and parallel:

Stick the square adapter atop the headers, solder all eight pins, glue down the SOT23, and solder it with wire-wrap snippets. Ugly, but workable…
