Laser additive manufacturing of embedded 3D circuit system and microstructure manipulation using Gaussian and holographic optical elements reconstructed beams

In Printed Circuit Board (PCB) manufacturing. making the conductive tracks 3D and embedding the electronic components in substrate can effectively reduce the circuit board volume, and improve the power delivery performance. Laser based additive manufacturing has been developed for many years but currently it is still used to create non-functional product. This PhD work will combine the two technologies together to generate a complete 3D embedded circuit system. hi addition. the laser beam will be reconstructed using Holographic Optical Elements (HOE) to control the microstructure of the product.
