2 Layer Flexible PCB Production Record #FPC-20260420-049

This production run involved 1000 units of 2-layer flexible PCBs configured in panels. Each board measured 11.7 x 9.7 mm with an overall thickness of just 0.11 mm, utilizing rolled copper foil at 1/3 oz per square foot. The design incorporated a yellow soldermask, white silkscreen, 0.2 mm minimum holes, and 6 mil minimum trace width and spacing, finished with immersion gold ENIG.

During manufacturing, particular attention was given to polyimide material handling and coverlay lamination to preserve the circuit's inherent flexibility. We applied the solder mask and performed electroless nickel and immersion gold deposition under controlled conditions. Dynamic FPC testing confirmed the boards' ability to withstand repeated bending, while batch AOI inspection and electrical testing ensured every panel met specification.

Completed over 17.9 days, the order achieved uniform quality with reliable electrical and mechanical performance. The resulting flexible circuits provide consistent solderability and long-term durability for their intended applications.
