The most troublesome thing about multilayer PCB design is interlayer interference. Signals are strung back and forth, which may cause bit errors or even a direct strike. To solve this problem, we have to start from the layout, routing and materials.
Rigid PCB, commonly known as hard board, is a printed circuit board made of a rigid substrate that is not easily deformed.
At present, there are many types of PCB boards, such as high-frequency PCB boards, microwave RF PCB boards and other types of printed circuit boards have already gained a certain popularity in the market. PCB manufacturers have specific processing technology for various board types. But in general, the PCB circuit board processing and production needs to consider three major aspects.
DFM (Design for Manufacturing) is the most effective way to ensure the quality of PCB SMT processing. DFM is a design practice and process that matches the engineering requirements of a product with global manufacturing capabilities to achieve the lowest cost, highest output, and speed up time to market. DFM considers manufacturability and testability from the time of product development and design, so that the design and manufacturing are closely linked to achieve the goal of one-time success from design to manufacturing. DFM has the advantages of shortening the development cycle, reducing costs, and improving product quality. It is the way for enterprises to achieve success.
What are the advantages of HDI PCBs? Phenomenal versatility: HDI boards are ideal where weight, space, reliability, and performance are primary concerns. Compact design: The combination of blind vias, buried vias, and microvias brings down the board space requirement.
