Wirelaid production processes

At the beginning of the Wirelaid process, the wires are fixed onto the under side of the copper foil using resistance welding.

The wire is then welded again at the end of the trace and cut to the appropriate length.

The "Wirelaid-copper foil" is then laminated onto a multilayer PCB using standard production processes. As a result the “Wirelaid-copper foil” forms the external layer of the PCB. Finally the outer tracks are created using standard PCB processes.

The contacting of the wires is achieved directly under a pad:
