Components and connections -[ HMM ]-

A small portion of one of the circuit cards inside a Dolby CP65 cinema sound processor, a long-discontinued model that was introduced before 35mm films contained digital soundtracks.

 

This card has circuit traces (its “wiring,” in a sense) on both sides of the card, an improvement over the traditional way circuit boards were made. I backlit the card to reveal the circuit traces on both sides.
