When I started soldering everything was big and had leads that went through holes in the board. You inserted the leads, bent them over to hold the component, flipped the board over, soldered everything, and trimmed off the excess leads.

Now I’m soldering things down to 0402 SMDs (1/4 the size of the smallest component in the picture) using a needle point soldering tip and a microscope.

A pair of 2N2222 transistors, one SOT23 and one TO-92.

    I’ve seen the tiny ones. I think I’m more likely to build a small reflux oven. I only ever build one or two of anything unless I take in a job for someone else.
