What it is：
Any PCB Board with more than 2 layers can be called Multilayer PCB Board .
Multilayer PCB Board includes multi-layer etch layers and medium layers between each two etch layers.The medium layer can be very thin. There are at least three conductive layer in a multilayer circuit board , two of which are outlayers, while the remaining one is synthesized inside the insulation board.
The electrical connection between them is usually achieved through the plating hole in the cross section of the circuit board.
Classify: Multilayer rigid board, multilayer flexible board and multilayer rigid-flex board.
Why we need it:
Cause the increased concentration of integrated circuit package leading to a high concentration of interconnect lines, It makes it necessory to use the multiple substrates.
Unpredictable design issues such as noise, stray capacitance, crosstalk, etc. occur in the layout of the PCB. Therefore, the design of PCB must focus on minimizing the length of the signal line and avoiding parallel paths.
Obviously, due to the limited number of crossovers that can be achieved in a single-side, even in a double-side board, these requirements cannot be satisfied.
In the case of a large number of requirements in interconnections and crossovers, to achieve a satisfactory performance, the board must be expanded to more than two layers, so a multilayer PCB board is manufactured.

A multilayer PCB board manufacturer offers a wide range of services and capabilities related to the production of multilayer printed circuit boards (PCBs). Here is a more detailed explanation of what a multilayer PCB manufacturer can do:
PCB Design Review: A multilayer PCB manufacturer can review the PCB design files provided by the customer. They carefully analyze the design to ensure it is manufacturable and meets the required specifications. If any issues or potential improvements are identified, they provide valuable feedback and suggestions to optimize the design for manufacturing efficiency and reliability.
PCB Prototyping: Prototyping is a crucial step in the PCB manufacturing process. Multilayer PCB manufacturers can produce prototype boards based on the provided design files. Prototyping allows for testing and validation of the design before proceeding to large-scale production. It helps identify any design flaws, performance issues, or compatibility problems early on, saving time and resources.
Layer Stack-up Configuration: Multilayer PCBs consist of multiple layers of conductive material and insulating layers (prepreg) sandwiched together. The manufacturer determines the layer stack-up configuration based on the design requirements and specifications. They consider factors such as signal integrity, power distribution, impedance control, and thermal management to optimize the performance of the PCB.
Copper Weight and Thickness: Multilayer PCB manufacturers provide options for copper weight and thickness for the inner and outer copper layers of the PCB. The selection of copper weight depends on the current-carrying capacity and thermal considerations. By offering a range of options, manufacturers can tailor the PCB's copper features to meet specific design requirements.
PCB Fabrication: Fabrication is the process of physically creating the multilayer PCB based on the design specifications. Multilayer PCB manufacturers have the expertise and equipment to execute various fabrication steps, including layer alignment, copper etching, drilling, plating, solder mask application, and silkscreen printing. They ensure high precision and adherence to design specifications throughout the fabrication process.
Surface Finish: The surface finish of a PCB is essential for solderability and protection against corrosion. Multilayer PCB manufacturers offer different surface finish options such as HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), OSP (Organic Solderability Preservative), or immersion tin. The choice of surface finish depends on factors like cost, lead-free requirements, and the intended application of the PCB.
Electrical Testing: To ensure the functionality and performance of multilayer PCBs, manufacturers conduct electrical testing. This involves various tests such as continuity testing, impedance testing, and functionality testing. Advanced testing methods like flying probe testing or automated optical inspection (AOI) may also be employed to detect potential defects or faults.
Quality Control: Multilayer PCB manufacturers have stringent quality control measures in place. They perform visual inspection, dimensional checks, and automated testing to ensure the final PCBs meet the required standards and specifications. Quality control processes help identify and rectify any manufacturing defects, ensuring the reliability and durability of the finished PCBs.
Customization and Special Requirements: Multilayer PCB manufacturers can accommodate specific customization and special requirements. They have the capability to handle factors like controlled impedance, high-speed design considerations, specific material choices, blind and buried vias, and unique design constraints. Manufacturers work closely with customers to understand their specific needs and provide tailored solutions.
Large-Scale Production: Once the prototype and testing stages are complete, multilayer PCB manufacturers can handle large-scale production to meet the customer's production needs. They have the capacity and resources to deliver consistent quality and timely production of multilayer PCBs in large quantities.
In summary, a multilayer PCB manufacturer offers a comprehensive range of services including PCB design review, prototyping, layer stack-up configuration, fabrication, surface finish options, electrical testing, quality control, customization for special requirements, and large-scale production. Their expertise and capabilities ensure the efficient and reliable production of multilayer PCBs for various applications and industries.
