Solder mask or cover film openings- During fabrication after exposure to processes like pumice scrubbing, copper plating, and/or etching flexible, the circuitry can demonstrate dimensional change. Flexible circuitry design rules usually need huge tolerances to accommodate subsequent registrations for die-cutting, cover film or stiffeners. The major point is with Metal Core PCB software designing a flex circuit can result in some serious manufacturability and reliability issues.
