Manufacturing Summary
This production record details a 4-layer flexible printed circuit manufactured in panel format with rolled copper and a finished thickness of 0.23 mm. Measuring 150 by 15.1 mm, these boards featured a challenging 3/3 mil minimum track and spacing alongside 0.15 mm holes. The yellow soldermask paired with white silkscreen created a distinctive appearance, while PI and FR4 stiffeners were added to selective areas for component support.
During manufacturing, polyimide material handling received special attention to preserve the integrity of the thin laminate. Inner layer imaging gave way to precise circuit etching, high-pressure lamination, and FPC coverlay application. Immersion gold ENIG provided excellent solderability and corrosion resistance on the half-ounce copper.
Following solder mask application and surface finishing, we conducted dynamic flex testing to validate performance under repeated bending. Electrical testing on all 20 panels confirmed full functionality. The entire process extended over 19.1 days, allowing for thorough quality checks at each critical stage and delivering reliable flexible circuits tailored to the specified parameters.
