Low-cost Laser Cutter and PCB exposure

Downward trend in laser technology price and increase of the accuracy achieved has allowed it to acquire a new dimension in recent times. This paper proposes, with a practical approach, focusing on the RF field, the use of an innovative low-cost laser technology as part of the practical syllabus of an Advanced Electronics Prototyping Techniques course or similar. It provides with conceptual understanding on industrial manufacturing limitations while studying different materials engraving, professional software suites and PCB Exposure, in contrast with the expensive CNC milling methods typically used, an alternative cheaper laser engraving technique for RF is exposed.”.
