When I&apos;m using perfboard, i like to design the layout of the components directly on the board. When the entire circuit is laid out, there&apos;s no easy way to turn the board for soldering. Inspired by a rack Bigclive used in a video (<a target="_blank" rel="noopener noreferrer" href="https://www.youtube.com/watch?v=wO192EU4BGQ">https://www.youtube.com/watch?v=wO192EU4BGQ</a>), I made this jig.<br><br>The idea is quite simple. Use a perfboard the same size as the one the circuit is on, as a holder for the foam. Use standoffs so that the foam is pressed enough to keep the components firm. I have cut some corners in the foam, to keep it in place. Hold the two boards in one hand, while screwing the board with the circuit on. <br>As the pictures show, even though there seem to be a gap above the TO-220 package, the socket still have its short legs through the board.
