Laser Drill & Laser Direct Imaging:  Technology for High Quality HDI PCB Manufacturing

HDI PCB designs push the limits of technology and Advanced Circuits is at the forefront of innovation, satisfying the most rigorous requirements.

The demand for HDI PCB manufacturing has been increasing due to the advancements in technology and the many benefits HDI PCBs provide for high-tech applications.  Fitting more technology in less space with fewer layers creates limitations for many PCB manufacturers that do not have the specialized equipment and the capacity for advanced features, finer lines, and tighter tolerances.  HDI printed circuit board designs utilize a combination of advanced features like microvias, blind vias, via-in-pad, along with stacked and staggered vias to maximize the the space of the board while increasing its performance and functionality.

Advanced Circuits achieves high quality and precision with in-house laser drill capabilities that include precise depth control.  Laser direct imaging (LDI) capabilities ensure exacting registration and all multilayer inner cores receive a thorough check using Automated Optical Inspection (AOI) units for excellent defect detection of the finest features.
