Technical details and manufacturing context for PCB

Definition
Within a camera module, the PCB serves as the foundational platform that interconnects the image sensor, lens assembly, autofocus mechanisms, and other electronic components. It routes electrical signals between these elements, provides power distribution, and often includes control circuitry for camera functions.
Working Principle
The PCB uses conductive copper traces etched onto a non-conductive substrate to create electrical pathways. Components are soldered onto designated pads, allowing electricity to flow through the traces to connect different parts of the camera module according to the designed circuit layout.
Common Materials
FR-4 (glass-reinforced epoxy laminate), Copper foil, Solder mask, Silkscreen ink
Technical Parameters
  • Board thickness typically ranges from 0.8mm to 1.6mm for camera modules (mm) Per Request
Components / BOM
  • Substrate
    Provides mechanical support and electrical insulation
    Material: FR-4 (glass-reinforced epoxy)
  • Copper Traces
    Conductive pathways that carry electrical signals between components
    Material: Copper
  • Solder Mask
    Protects copper traces from oxidation and prevents solder bridges
    Material: Polymer resin
  • Silkscreen
    Provides component identification and assembly markings
    Material: Epoxy ink
Engineering Reasoning
15-85°C ambient temperature, 0-95% relative humidity non-condensing, 0-2000 m altitude
Glass transition temperature (Tg) of FR-4 substrate at 130°C, copper trace delamination at 260°C reflow temperature, dielectric breakdown at 500 V/mm for 1.6 mm substrate
Design Rationale: Thermal expansion coefficient mismatch between copper (17 ppm/°C) and FR-4 epoxy (14-18 ppm/°C) causing mechanical stress, electrochemical migration at >85% RH with >5 ppm ionic contamination
Risk Mitigation (FMEA)
Trigger Tin whisker growth from pure tin plating under 0.5-20 MPa compressive stress at 50-150°C
Mode: Short circuit between adjacent 0.2 mm pitch components
Strategy: Nickel barrier layer (3-5 μm) under tin finish, conformal coating with 25-75 μm acrylic or silicone
Trigger Electromigration at current density >10^5 A/cm² in 35 μm copper traces at 125°C
Mode: Open circuit in power distribution network
Strategy: Trace width calculation using IPC-2152 derating curves, 50% current derating at 100°C
