Advantages of rigid PCB
The rigid PCB has a certain mechanical strength, and the parts assembled with it have a flat state. Rigid printed circuit boards are used in general electronic products.
High-density: For more than 100 years, the high-density of printed boards have been able to develop with the improvement of integrated circuit integration and the advancement of installation technology.
High reliability: Through a series of inspections, tests, and aging tests, the rigid PCB can be guaranteed to work reliably for a long time (usually 20 years).
Designability: For PCB performance (electrical, physical, chemical, mechanical, etc.) requirements, printed board design can be realized through design standardization and standardization, with short time and high efficiency.
Manufacturability: The use of modern management can carry out standardization, scale (quantity), automation, and other production to ensure product quality consistency.
Testability: A relatively complete test method, test standard, various test equipment, and instruments have been established to detect and appraise the eligibility and service life of PCB boards for sale.
Different types of rigid PCB can meet different requirements
A single-layer rigid PCB with traces and components on one side provides basic functions and low cost while matching simpler products with fewer functions. There are traces and components on both sides of the double layer printed circuit board, and the substrate is sandwiched between conductive layers. Thicker multilayer rigid circuit boards have multiple layers, which are divided into signal, power, and ground layers by dielectric materials. The multilayer circuit board is suitable for high-density applications with higher speed and operating frequency.
How to design a rigid PCB board?
When designing a multilayer rigid printed circuit board, always start with an even number of layers. The thickness of the dielectric used for the circuit board depends on the type of material, size, and tolerances required by the application. A good rigid PCB manufacturer can establish a layout that is balanced according to the z-axis of the circuit board. Balancing the dielectric thickness of each layer, the copper thickness of each layer, the distribution of copper, and the position of the signal layer, ground layer, and power layer can ensure that the circuit board meets bow or twist specifications.
