[Danko]’s minimal circuit is about as small as possible for the DIP version of the venerable 555 chip. The BOM is stripped to the bone: just the chip, three resistors, a capacitor, and an LED.
A bare chip that is mounted directly onto the printed circuit board (PCB). After the wires are attached, a glob of epoxy or plastic is used to cover the chip and its connections. The tape ...
As demand for next-generation semiconductor chips grows, a team of researchers has succeeded in laser-drilling the world's tiniest circuit board holes, measuring a near-inconceivable 3 micrometers ...
