Printed Circuit Board, can be categorized according to its functions and utility as Aluminum substrates PCB with has been used widely on the scenarios where can generate great amount of heat and need to dissipate through the aluminium base which can be served as heatsink, high frequency PCB boards which can be used for the product with high speed transmission requirement, ultra-thin circuit boards which can be used on the device with limited space, etc., are important electronic components and are the support of electronic components. Body is the provider of the connection of electronic components.
The traditional printed circuit board uses the method of printing etch resist to make the circuits, so it is called a printed circuit board. Due to the ever-increasing miniaturization and refinement of electronic products, most of the current printed circuit boards use an etch resist (film or coating), and after exposure and development, the circuit board is etched.
