. HDI PCBs can dramatically lower the number of layers needed to function. For products that rely on small design constraints, these printed circuit boards are a necessity

. The layout design is a critical step in confirming the manufacturability of the PCB and is typically guided by the rules and constraints set by the PCB manufacturer

. They may also be subject to heavy vibrations, and cannot rely on rigid forms. With these constraints in mind, we now turn to how printed circuit board designers and manufacturers go about solving these issues to ensure a clear, fast, and reliable signal in the devices that connect the world

. Wearables, in particular, require tiny PCBs, imposing constraints on layout, space, and weight. Wearables must have very small PCBs due to their size and unconventional shapes

. The potential challenges of 3D printing to create PCBs include material limitations and design constraints. For example, manufacturers need rigid semiconducting materials to optimize for different frequency bands

primarily driven by the ongoing need for miniaturization, resulting in numerous design constraints. It also means that designers and manufacturers must work together more closely to achieve further improvements in this maturing technology. At Imagineering
