HDI boards, one of the fastest growing technologies in PCBs, are now available at Suntech tech. HDI Boards contain blind and/or buried vias and often contain microvias of .006 or less in diameter. with finer lines and spaces, higher connection pad density.
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.
HDI PCB Applications
HDI boards are appropriate for a wide range of industries. you'll find them in all types of digital devices, like smartphones and tablets, where miniaturization is key to the effective application of the product. You can also find high-density interconnect PCBs in automobiles, aircraft and other vehicles that rely on electronics.
One of the most critical areas where the high-density PCB is making huge inroads is in the medical arena. Medical devices frequently need small packages with high transmission rates that only HDI PCBs can supply. For example, an implant needs to be small enough to fit in the human body, but any electronics involved in that implant absolutely must efficiently allow for high-speed signal transmission. Here, the HDI PCB indeed is a godsend. HDI PCBs can also be useful in other medical equipment, like emergency room monitors, CT scans and much more.
