Advanced Manufacturing Techniques of FPCB for CCM(Compact Camera Module)

FPC inside the Compact Camera Module — FPC inside the CCM, breakdown of compact camera module

The breakdown of compact camera module, the FPC inside the CCM.

CCM, Short for Compact Camera Module.

CCM comprises four main components: Sensor, Lens, DSP, FPCB (Flex PCB as connector, also, as FPC Frame).

The crucial components determining the quality of a camera are the lens, image processing chip (DSP), and sensor

镜头, Lens

镜座, Lens Holder

电容, Capacitor

电阻, Resistor

CMOS感应器, CMOS Sensor

How it works

Light gathered through the lens is converted into electrical signals by the CMOS or CCD integrated circuit. These light signals are then processed into digital image signals by the ISP, internal Image Signal Processor and output to the DSP, Digital Signal Processor for further processing, resulting in standardized image signals such as GRB, YUV, etc.

Flex Plus Key Manufacturing Technical Features of FPCB for CCM(Compact Camera Module)

1.High Precision of Solder Pads for BGA Structure

The minimum solder pad size in BGA mounted on FPCB for CCM(Compact Camera Module) can be achieved with precision as small as 0.2mm. The solder pad position accuracy controlled within ±0.05mm.

2.High Uniformity of Copper Plating in Vias High Precision in Alignment of Double-Sided Circuits.

The surface uniformity of copper plating can achieve ±2um, and the copper on vias is maintained at ≥12um, fully meeting the reliability requirements of FPC.

3.High Precision in Alignment of Double-Sided Circuits

The alignment tolerance of double-sided circuits is within ±0.07mm.

4.Exceptional Performance Assurance for FPC

Soldering rate on solder pads ≥98%, ensuring excellent soldering performance
SMD design adopted in critical pad areas, ensuring strong solder pad adhesion
Impedance value controlled within ±8% tolerance.
