In today’s daily life, every electronics around you- most of them are tagged as “SMART” because they are operating automatically with high efficiency and effectiveness. The internal system of such electronic devices consists of printed circuit boards (PCBs) doing basic to complex functions. Most of the PCBs being manufactured today are still made from rigid PCBs. Most of the PCBs being manufactured today are still made from rigid PCBs by a rigid PCB manufacturer.
What is a Rigid PCB?
A solid and inflexible form of Printed Circuit Board and therefore it cannot be bent or flexed are commonly used in the electronic industry. Due to its stability and structure- called a Rigid PCB usually are of single sided, double sided, multilayers or carrier board or mechanical spacer boards with standard FR-4 to varieties of materials and having simple to complex technologies. A rigid PCB manufacturer often offers a wide range of options depending on the application requirements.
What materials are used to build Rigid PCBs?
There are several materials used to build the Rigid PCBs like FR-4 material, High TG FR-4 material, Specialized High-speed materials, Copper Core, Ceramic material, PTFE material etc.All the materials have different characteristics and purpose of use.
What are the technical aspects, structure and characteristics of Rigid PCBs?
There are lots of aspects contributes the manufacturing of Rigid PCB like, Single to multilayers construction (1 to 40 layers build), Design considerations and complexity (simple through hole technology to high definition with via fill, impedance requirement, blind-buried via, high copper thickness etc.), Material requirements (standard FR-4 to specialized materials), Technology requirements (HDI, RF, microwave, metal core, Metal core+FR-4 boning. Control depth etc.) also different solder mask types and colors, silk colors and surface finishes are part of the Rigid PCB. The mechanical spacer boards and Specialized carrier boards are also the Rigid PCBs manufactured with their own purpose.
What are the main features of Rigid PCBs?
Rigid PCB is a traditional Printed Circuit Board that has wider use in several industries having some features like stiffness and rigidity, solid substrate material, higher functionality, high reliability, manufacturing efficiency having thermal and dimensional stability etc.
Let’s highlight these main features:
-
Stiffness and rigidity:
Once the Rigid PCB is manufactured, it cannot be bent or folded. As the name indicates, they are stiff.
-
Solid substrate material:
Most common material used to build the Rigid PCB is FR-4 which provides excellent mechanical support and electrical insulation with thermal stability. FR-4 material is flame retardant, and it meets 94V-0 standards.
-
Higher functionality:
Rigid PCB can be manufactured as a single layer, double layer or with several multi layers construction with wide range of board design flexibility which provides high voltage and current carrying capacity.
-
High reliability:
Because of their structural rigidity and durability, the Rigid PCB are resistant to deformation. They can be used in most applications with high reliability and last for a longer period of time.
-
Manufacturing efficiency:
The Rigid PCB is the earliest technology in Printed Circuit Board Industry, which is very efficient, automated, standardized and well developed. Choosing an experienced rigid PCB manufacturer in USA ensures the best results for industrial-grade applications.
-
Thermal and Dimensional stability:
Because of having higher thermal and dimensional stability, the Rigid PCB always maintains their shape and size under various conditions and temperature fluctuations.
What are the advantages of using Rigid PCBs?
Rigid PCBs are proven reliable and can conveniently be used for various projects with different specifications, configurations with different technology in several electronic devices ranging from general electronics to computer mother boards to military and aerospace technology products. Rigid PCBs are less expensive compared to other complex and high-tech PCBs.
Rigid circuit boards have lower design and development costs and lower installation costs. Thus, most devices and instruments make use of Rigid PCB, driving high demand for reliable rigid PCB manufacturer services.
What are the different applications of Rigid PCB?
The Rigid Printed Circuit Boards are widely used in consumer electronics, automotive, military, industrial and medical devices. Some of the examples of Rigid PCBs usage are computer motherboards, storage devices, cell phones, other communication devices, automotive electronics, medical equipment, industrial electronics like control systems and instruments.
