2 Layer Flexible PCB Production Record #FPC-20260409-054

For this flexible PCB order, production focused on 1000 panels of 2-layer construction using rolled copper on 0.2 mm thick polyimide material. The distinctive long and narrow 4 x 250 mm dimensions required specific handling techniques during lamination and processing to prevent distortion. With a yellow soldermask, white silkscreen, and added PI stiffeners, these boards combined visual customization with functional reinforcement in critical areas.

We executed the circuit patterning at 6/6 mil resolution, which falls within standard flexible PCB parameters, followed by coverlay application for protection. The immersion gold ENIG finish was carefully deposited after nickel plating to deliver superior conductivity and oxidation resistance suited for flexible applications. Dynamic flex testing formed a key part of validation, simulating real-world bending cycles to confirm durability.

Throughout the 10-day manufacturing period, AOI inspections and electrical tests maintained quality consistency across the batch. This execution delivered reliable flexible circuits that met the exact thickness, material, and performance criteria specified.
