Innovations in Rigid PCB Design and Fabrication

Rigid PCB (printed circuit board) is a key component in modern electronic equipment, the main advantage is its structural stability. Compared to flexible printed circuit boards, rigid PCBS are more physically stable, less prone to bending or twisting, and can accommodate more components and connections. Due to their rigid structure, rigid PCBS can support larger components and more complex circuit designs. This makes them useful in high-performance applications where large amounts of data and signals need to be processed, such as computers and communication equipment.

Immersion Silver is a common surface treatment technique used in the manufacture of Rigid PCB. Silver immersion surface treatment involves depositing a thin layer of silver on the PCB surface to provide good conductivity and weldability, environmental protection. The advantages of silver impregnated surface treatment are good weldability, low resistance and good electrical properties. Due to the presence of the silver layer, the silver impregnated PCB can provide stable welding performance, so that the components can be reliably welded to the PCB. The silver layer can also provide lower resistance, thereby improving the performance of the circuit.

Rigid printed circuit board (Rigid PCB) is widely used in electronic equipment, its main advantages are as follows:

1. Stability: The main advantage of rigid PCB is its structural stability. Compared to flexible printed circuit boards, rigid PCBS are physically more stable and not easily bent or twisted.

2. Large capacity: Another advantage of rigid PCBS is that they can accommodate more components and connections, supporting larger components and more complex circuit designs.

3. Durability: Rigid PCB has good durability and can maintain its performance under various environmental conditions, including high temperature, high humidity and high pressure.

4. Cost effectiveness: The manufacturing cost of rigid PCB may be higher than that of flexible PCB, but due to its stability and large capacity, rigid PCB can provide higher cost performance.

The advantages of Rigid PCB make it play a vital role in modern electronic equipment. Whether it is stability, large capacity, durability or cost effectiveness, rigid PCBS can meet the needs of a variety of applications.

In the manufacturing process of Rigid PCB, surface treatment is a key step. Organic Solderability Preservative (OSP) is a common surface treatment technique. OSP surface treatment involves coating the PCB surface with a thin layer of organotin protective film. This treatment method provides good welding performance, but also provides a certain amount of environmental protection. The advantages of OSP surface treatment include good weldability, lower cost and environmental protection. Due to the presence of organotin protective film, OSP-treated PCBS can provide stable welding performance, so that components can be reliably welded to the PCB. In addition, the cost of OSP treatment is relatively low, which can reduce the total cost of PCBS. The materials used in the OSP treatment are environmentally friendly and meet the green manufacturing requirements of modern electronic devices.
