From Copper Foil to Precision Circuits: How We Use "Light" to Carve a Micron-Level City on a #PCB
Every electronic device you hold contains a miniature city.
How are those traces, finer than a strand of hair, precisely "grown" onto the PCB?
In this video, we'll take you straight into the core workshop of PCB outer layer fabrication, with an uncut, real-time recording:
🔬 The Mysterious "Photolithography": How is light used to transfer the design blueprint onto the copper board?
⚗️ Precise "Etching": How is the excess copper foil made to "vanish," leaving behind only the perfect circuit traces?
Watch now and see the "skeleton" of tech products come to life!
