For this order of ten 6-layer flexible PCBs, production centered on a thin 0.23 mm construction utilizing 1/2 oz rolled copper and polyimide base material. The 174 x 174 mm single boards presented a minimum track and spacing of 4/4 mil together with 0.15 mm holes, demanding careful imaging and etching. Yellow solder mask, white silkscreen, immersion gold ENIG surface finish, and FR4 stiffeners were integrated to match the specified requirements.
Execution involved detailed polyimide material handling and precise layer stack alignment ahead of high pressure lamination. Coverlay lamination preceded solder mask application, followed by the full ENIG process consisting of electroless nickel deposition and immersion gold. These steps ensured the thin flex layers maintained integrity throughout manufacturing.
Dynamic flex testing formed a key part of the verification, supplemented by comprehensive electrical testing. The resulting boards exhibited consistent quality and performance, delivering reliable flexible circuits suited to the customer's application needs.
