The combination of microwave-induced pyrolysis and mechanical processing is a promising way to recycle the waste printed circuit boards (WPCBs). In pyrolysis, WPCBs yield an average of 78.6 wt.% solid ...

As an undergraduate student, Yufeng Chi (B.S.'23 EECS) was captivated by humanoid and legged robots. Eager to learn more, he ...

Conductor (copper) foil surface roughness in printed circuit boards (PCBs) is inevitable due to adhesion with laminate dielectrics. Surface roughness limits data rates and frequency range of ...

Solution-based printing has contributed to the facile deposition of various types of materials, including the building blocks of printed electronics. In particular, solution-processable organic ...

In this paper, we develop and put into practice an automatic optical inspection (AOI) system based on machine vision to check the holes on a printed circuit board (PCB). We incorporate the hardware ...

In article number 2401901, David Estrada and co-workers demonstrate a new approach to flexible PCB manufacturing. Through the use of Pd nanoparticle catalysts embedded in laser-induced graphene ...

Virginia Tech team develop new kind of circuit board that can heal and be reshaped, potentially solving the world's growing e-waste problem.

The circuit boards are remarkably resilient and functional. Even under mechanical deformation or damage, they still work. Michael Bartlett, Associate Professor, Mechanical Engineering, Virginia Tech.

A new class of circuit board material combines recyclable vitrimers with liquid metal droplets, enabling circuits that are electrically conductive, self-healing, reconfigurable, and durable. These ...
