Front side of chip. Blue “box” capacitor (sorry, forgot the name of these right now) soldered to the power and ground pins of the chip.

I don’t know what to call this technique. Yes, this does work. It’s a QUAD 2-INPUT AND GATE (HCF4081BE chip) with 10k pull-down resistors on each input and 15nF decoupling capacitor between the power and ground pin. Everything soldered directly to the chip, expect the output pins. Looks like a spider!!
I plan on making a modular system that is basically just chips soldered to panel, so to speak.
