The thickness of copper used in PCBs has a significant impact on the overall performance and reliability of the board. Whether you are a PCB designer, engineer, or electronics enthusiast, understanding the importance of copper thickness is essential for achieving desired functionality and meeting specific application requirements.
A printed circuit board, or PCB, is an insulating board that holds and connects electronic parts. The conductive paths on these boards are used to connect the different parts of an electronic device.
The aluminum substrate shines in the LED lighting electronics industry because of its excellent heat dissipation performance and dimensional stability, and the processing controllability of the FR4 glass fiber PCB board is irreplaceable in HDI high-density interconnection and high-end electronic technology.
FR-4 stands for a specific glass fiber reinforced epoxy laminate material and were designated by the National Electrical Manufacturers Association.
Immersion tin is a relatively new process, and it has not yet become as popular as HASL. However, its environmental benefits and its ability to produce high quality finishes are making it increasingly popular.
When connecting the input and output from one electric circuit to the next, in principle, it is necessary to match the impedance of each. Connecting with a coaxial cable (structure like a TV antenna) is the most stable, but the impedance control board reproduces this on a printed circuit board.
Castellated PCBs are often used in applications where space is limited, such as smartphones and other portable devices, because of these indentations that allow them to be soldered to another PCB or module. They provide a secure and reliable connection.
It has a structure in which a base film (such as polyimide), which is a thin-film insulator, is used, and an adhesive layer and conductor foil are laminated on it.
The product consists of 5 or more dielectric layers. When using multilayer PCB, the dimensions of the final device are reduced, and the design complexity increases significantly.
A component called a coil (inductor) uses the magnetic field generated when this current flows. A coil (inductor) has two major roles, one of which is to store energy. The other role is to prevent AC current from flowing (which depends greatly on the frequency).
Since both sides cannot be electrically connected as they are, conductors such as copper plating are applied to connection holes called via holes to electrically connect the wiring patterns on both sides.
With the emergence of next-generation power devices, the power electronics field is becoming increasingly high-frequency, and the effects of parasitic components such as inductance, capacitance, and resistance on circuits, which were previously ignored, will become apparent.
