High-density interconnect (HDI) PCBs have become a standard in modern electronics, enabling designers to create smaller, more functional devices. However, designing HDI PCBs requires careful attention to detail due to their complexity and the advanced technologies involved. This article outlines key HDI PCB design guidelines, highlights the advantages and disadvantages of HDI layouts, and provides insights into overcoming common challenges.
In the present world, especially in the current technological era, devices are becoming more compact and advanced. For implementing the compact and at the same time advanced electronic technology in the world, HDI PCBs contribute abundantly
Rigid-Flex boards are a combination of rigid boards and flexible circuits that are permanently laminated together and interconnected through through-holes. Rigid-Flex boards are also written as Flex-Rigid. Rigid-Flex boards straddle the boundaries of traditional rigid boards and the unique properties of flexible circuits, using highly ductile ED or RA copper photolithography onto a flexible insulating film
