Manufacturing Summary
This production record covers 50 pieces of 4-layer rigid-flex PCB, each measuring 28 × 18.5 mm and built to a total thickness of 0.3 mm. The design required 3/3 mil trace and spacing, 0.1 mm minimum hole size, blind vias, and 1 oz copper on all layers. These features, combined with the thin cross-section, called for precise material preparation, inner layer imaging, and controlled etching to maintain registration and electrical integrity throughout the rigid and flex zones.
Layer stack alignment was followed by flex-rigid lamination under high pressure to ensure reliable bonding at the transition areas. Black soldermask and white silkscreen were applied prior to electroless nickel deposition and immersion gold plating, producing a uniform ENIG surface finish. Controlled depth routing then defined the final outline while protecting the flexible sections.
Dynamic flex reliability testing and 100 % electrical testing verified performance under repeated bending and confirmed impedance stability. The 5-day manufacturing cycle allowed careful validation at each critical step, resulting in consistent quality across the full lot and meeting the mechanical and electrical demands of this thin rigid-flex configuration.
