1.1 General description
This is a type of assembled flexible PCB built on polyimide substrate with Tg 60°C for the
application of Portable Sound System. It's 2 layer FPC at 0.15 mm thick, white silkscreen
on yellow coverlay(solder mask) covering both sides and immersion gold on pads. Polyimide
as stiffener is on the back of one end. The base material is from Shengyi, entire board supplying
34 PCBs per panel. They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each
25 panels are packed for shipment.
