4-layer solder mask custom FR4 custom multilayer board PCB

   4-layer solder mask custom FR4 custom multilayer board PCB is a printed circuit board composed of three or more layers of circuits. Each layer of circuits is composed of different circuit layers, and these layers are connected together through vias or interconnecting lines. Compared with single-sided and double-sided PCBs, multi-layer PCBs can achieve more circuit wiring in a smaller space and are suitable for more complex and function-intensive circuit designs.


Main Application Equipment:

•Telecommunications (5G modules, routers)

•Industrial control systems

•Medical devices

•Automotive electronics

•LOT and smart hardware



Why Choose our brand?
✔ 30 Years Expertise in Rigid-Flex PCB Manufacturing

✔ Global Shipping (DHL, FedEx, UPS) – Delivered to USA, Germany, UK, Japan, Australia, etc.



Key Manufacturing Challenges of Multilayer PCBs 

  • 1.Lamination & Alignment Accuracy
    As the number of layers increases, cumulative errors become larger. Extremely high alignment precision (e.g., ±75μm) is required to prevent sliding or misalignment. Simultaneously, resin flow, bubbles, and delamination risks must be strictly controlled during the lamination process.
    2.Drilling & Plating Difficulty
    Thicker boards result in deeper holes and high aspect ratios, making drilling prone to broken drills or uneven diameters. Drilling special materials (such as high-Tg or high-frequency laminates) is difficult, often resulting in rough hole walls and challenging desmearing (de-drilling smear) processes.
    3.Inner Layer Circuitry
    High-density designs require extremely fine line widths and spacings. Thin inner core materials are highly susceptible to creasing or wrinkling during etching and handling, which affects circuit yield.
    4.Impedance & Signal Integrity
    For high-speed and high-frequency applications, strict control over dielectric thickness, copper roughness, and CAF (Conductive Anodic Filament) risks is required to maintain stable impedance and prevent interlayer leakage.
    5.Inspection & Reliability
    As circuit density increases, the false positive and false negative rates of traditional optical inspection (AOI) rise. Furthermore, Coefficient of Thermal Expansion (CTE) management is critical to prevent (popcorning/delamination) or cracking under thermal shock.
