On an ultra-high-density wiring substrate, thousands of tiny wires are precisely laid out in a very limited space. This highly dense design allows a large number of electronic components to be integrated in a limited space, thereby achieving more complex circuit functions.

In ultra-high-density wiring substrates, fine wires are usually manufactured through advanced printing technology and etching processes. These wires are usually constructed of highly conductive materials, such as copper or silver, and are embedded in a special insulating substrate to ensure the stability and reliability of the circuit.

The design and manufacturing of ultra-high-density wiring substrates require highly precise processes and technologies. Engineers must consider factors such as routing rules, signal integrity, thermal management, and electromagnetic compatibility to ensure circuit performance and stability.

Overall, ultra-high-density wiring substrates play an integral role in modern electronic devices.
