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 good PCB factory should possess the following characteristics:
Experience and Expertise: A reputable PCB factory should have years of experience in the industry and a team of skilled professionals who are knowledgeable about PCB manufacturing processes, technologies, and industry standards.
Quality Assurance: A good PCB factory should prioritize quality control measures throughout the manufacturing process. They should have robust quality control systems in place, including inspections, testing, and adherence to industry standards and certifications (such as ISO, UL, or RoHS).
Advanced Manufacturing Capabilities: The factory should have modern equipment, machinery, and technologies to handle various PCB manufacturing requirements, including the ability to produce different types of PCBs (single-sided, double-sided, multilayer, rigid-flex, etc.) and work with a range of materials.
Flexibility and Customization: A reliable PCB factory should offer flexibility in terms of accommodating custom design requirements, specific materials, and manufacturing specifications. They should be able to tailor their services to meet the unique needs of their clients.
Timely Delivery: Meeting deadlines and delivering PCB orders on time is crucial. A good PCB factory should have efficient production processes, effective project management, and clear communication to ensure timely delivery of PCBs.
Strong Supply Chain Management: The factory should have a well-established supply chain network and partnerships with reliable component suppliers. This ensures the availability of quality components and reduces the risk of delays or counterfeit parts.
Customer Support: Excellent customer support is essential for a good PCB factory. They should be responsive to inquiries, provide clear communication channels, and offer technical assistance throughout the manufacturing process.
Cost-Effectiveness: While quality is important, a good PCB factory should also offer competitive pricing without compromising on quality or reliability. They should provide transparent pricing structures and offer value for the services provided.
Continuous Improvement: A reputable PCB factory should demonstrate a commitment to continuous improvement, staying updated with industry trends, adopting new technologies, and investing in research and development to enhance their manufacturing processes and capabilities.
Strong Ethical and Environmental Practices: A responsible PCB factory should adhere to ethical business practices, comply with environmental regulations, and prioritize sustainability. They should demonstrate a commitment to minimizing waste, recycling, and using environmentally friendly materials and processes.
