Manufacturing of this order comprised ten 6-layer flexible PCBs built on rolled copper with an overall thickness of 0.23 mm. Measuring 14 x 37 mm, the single boards included FR4 stiffeners, yellow soldermask, and white silkscreen printing. The 6/6 mil minimum trace and spacing along with 0.3 mm holes presented a conventional geometry for the flex material, while the immersion gold ENIG finish provided stable surface properties for assembly.
Execution involved careful polyimide material preparation followed by inner layer imaging, etching, and accurate layer stack alignment before high pressure lamination. Coverlay application preceded the solder mask and surface finish stages, where electroless nickel and immersion gold were deposited. We conducted dynamic flex testing to verify the multilayer construction's endurance under mechanical stress.
Final electrical testing validated performance across the batch. The production sequence ensured layer registration and overall consistency for these thin flexible circuits, delivering reliable boards that align with the specified technical requirements.
