2 Layer Flexible PCB Production Record #FPC-20260803-025

For the order of 1000 2-layer flexible circuit boards, production focused on the unique geometry of these long, narrow circuits measuring 292.5 x 8.5 mm at just 0.1 mm thick. Fabricated with rolled copper at 1/3 oz on polyimide, the boards incorporated yellow solder mask, white legend printing, PI stiffeners, and immersion gold ENIG finish. The 6/6 mil trace spacing and 0.3 mm holes represented conventional geometry for this thin flex construction.

Processes centered on precise polyimide material handling to avoid damage to the delicate substrate. After circuit imaging and etching came coverlay lamination, solder mask application, and the electroless nickel with immersion gold deposition. Dynamic flex testing was performed to validate bending reliability, supplemented by batch AOI and full electrical testing.

Completed within 10.8 days, the run produced uniformly reliable flexible circuits. The combination of thin profile, custom stiffener placement, and specialized color scheme was executed to match the customer's exact requirements for form and function.
