Earlier, if your project included complex parts where standard methods could not accomplish, CNC machining was always the first choice. It allowed manufacturing fairly complex parts with multiple degrees of freedom. Sophisticated numerically controlled CNC machines can cut and spin in many directions with very high precision.

PCBs are still the best and most reliable way of connecting electronics components. PCB stands for Printed Circuit Board, on which electronic components are soldered on pads connected by conductive lines. PCB manufacturing technology continues to evolve as requirements of miniaturization, reliability, and flexibility grow. They come in different shapes, colors, use different base materials, and can even be flexible.
