Latest company news about High Frequency PCB Based on 20 mil Rogers 4350 laminate

There are many kinds of plates for making circuit boards. The materials used in different fields will also be different. Designers will choose different materials based on their transmission of different frequencies and signals.In the case of this PCB, the specifications include using RO4350 laminate material with a thickness of 20 mil, two layers (top and bottom), a silver finishing, a copper thickness of 35um (1 oz), and a board size of 101.6mm by 63.5mm.



One important consideration for this PCB is the use of RO4350 laminate material. This material is known for its high-frequency performance and is commonly used in applications such as cellular base stations, wireless infrastructure, and satellite communications. The 20 mil thickness is relatively thin, which can be advantageous for applications where space is limited.


The PCB is also designed with two layers, meaning that components will be populated on both the top and bottom layers of the board. This is a common approach for many PCB designs and can help to reduce the overall size and complexity of the board.


Another notable aspect of this PCB design is the lack of a solder mask or silk screen layer. Typically, these layers are used to protect certain areas of the board from being soldered accidentally and to provide labeling and text information about the PCB and its components. However, omitting these layers can result in a simpler, more minimalist design that may be appropriate for some applications.


To achieve the desired silver finishing, a specialized plating process will be required. Silver is an excellent conductor of electricity, and applying a finish of this type can help to improve the overall performance of the circuit board. This process involves coating the surface of the PCB with a layer of silver, providing enhanced connectivity within the board.



The copper thickness of 35um (1 oz) specified for this PCB is standard for many commercial applications and should be sufficient to handle most uses. Additionally, the note about filling vias with copper shows that there will be holes within the PCB that require filling to enable electrical connections between the top and bottom layers. This technique is commonly used in PCB design and production to ensure good electrical connectivity within the board.


Finally, the PCB size is relatively small, measuring 101.6mm by 63.5mm. This size could be suitable for many applications, but larger PCBs may require additional design considerations to ensure electrical signals do not degrade over longer distances.


In summary, the design and production of this PCB requires careful consideration and planning to ensure the final product meets all requirements and specifications. Using the right materials, optimizing the board layout, and carefully considering the application's needs are all essential steps in creating a high-quality PCB that functions appropriately and reliably.
