The structure of a PCB consists of two main parts: a substrate made from engineering plastics with excellent thermal and electrical insulation properties, and a circuit layer comprising copper foil, engraved according to design specifications to form the core circuit.
Certainly! Here’s a concise summary in English: Small batch PCB manufacturers specialize in rapid prototyping with efficient production cycles and prioritized urgent orders, offering fast turnaround times unmatched by larger facilities. Key processes include drilling for circuit connections, solder mask application to insulate areas, tin plating for oxidation resistance, and silk screen printing for annotations.
Aluminum nitride substrate is a versatile ceramic material with high thermal conductivity and excellent electrical insulation, making it suitable for a wide range of applications including high-temperature and high-power electronics, LED lighting, thermal interface materials, ultra-high-temperature packaging, high-power devices, high-frequency devices, and thin film materials.
PCB boards are mainly made of a non-conductive substrate material with copper circuit layers, electronic components, printed symbols and text, as well as solder joints, working together to form the overall structure and functionality of the circuit board.
The RT/duroid substrates are versatile, resistant to solvents and reagents, and offer low dielectric loss, making them ideal for high-frequency and broadband applications.
PCB is a crucial electronic component used for circuit connections and thermal management, while substrate is mainly used for supporting electronic components with simpler manufacturing processes.
