The above board is a 4L multilayer FPC with 0.5mm board thickness. All the copper from inner to outer are 1oz. The min line width is 4mil and the min line gap is 3mil. The min hole is 0.2mm. As the distance between PADs is dense, so besides the black cover film, we also use black solder mask for the dense PADs.

Product Feature And Application
Whether in the PCB manufacturing process and assembly process or in actual use, PCB should have a reliable performance, which is crucial. Strict control of the life of every kind of surface treatment can affect pcb reliable performance. The benefit of strict control of the life of every kind of surface treatment is to keep solderability and reliability, and reduce the risk of moisture intrusion. Every kind of surface treatment has their shelf life. For this pcb,the shelf life is 6 months, as this board's finishing is immersion AU.
