Like any other project you do, designing a printed circuit board requires a lot of trial and error to find the perfect PCB. As a student, it's important to try out some designs and see which one works best for the project you're working on. Fortunately, with free PCB Artist software provided by Advanced Circuits, [...]
First, the failure caused by capacitor damage is the highest in electronic equipment, especially in the electrolytic capacitor damage is the most common. Capacitance damage is shown as: capacity decreases; Total loss of capacity; The leakage; Short circuit. Capacitors play different roles in the circuit and the faults caused by them have their own characteristics. [...]
The design of printed circuit board (SMT) is one of the important components of SMT SMT assembly technology. The design quality of printed circuit board (PCB) is an important symbol to measure the technical level of surface assembly and one of the primary conditions to ensure the quality of surface assembly. Design for Manufacturing (DFM) [...]
Waste electrical and electronic products are also growing rapidly. As the core and foundation of electrical and electronic products, the casual abandonment and irregular recycling of circuit boards has brought serious environmental problems. On the other hand, waste circuit boards contain a large number of metals and non-metals with recycling value. Lvjie environmental protection circuit [...]
