One of the electronic components can be resistors, capacitors, integrated circuits, etc.,
Circuit board conformal coatings are specialized polymer film-forming products that protect circuit boards, components and other electronic devices from adverse environmental conditions. These coatings are not limited by the PCB structure or other environmental factors, but provide a higher dielectric resistance to protect the board from corrosive environments, humidity, and contaminants such as dirt and
PCB thickness usually refers to the thickness of the substrate, i.e. the distance between the conductive and insulating layers. This distance is small but has a significant impact on the overall performance of the board. The right thickness ensures the strength and stability of the board as it undergoes its daily work, while also helping
PCB coating, refers to the conductive layer of the circuit board, through a certain process method, covered with a layer of metal or other materials of the film. This film not only plays a protective role in preventing the circuit from oxidation, corrosion and other external factors, but also to improve the conductivity and stability
A test point pcb is a substrate on the circuit board of an electronic product that is specially designed for testing purposes. It usually contains one or more sets of Test Points, which are connection points between components on the circuit board for electrical performance testing and diagnostics during manufacturing, repair, or research and development.
Military circuit board, is specially designed circuit boards that are widely used in military applications. These circuit boards undergo rigorous testing and certification programs to ensure that they can continue to operate under extreme conditions.
