Common PCB layout constraint principlesThe following aspects are often considered in PCB component layout:(1) Does the PCB shape match the whole machine?(2) Is the spacing between elements reasonable? Are there any horizontal or high level conflicts?(3) Does PCB need to be assembled? Are process edges reserved? Are mounting holes reserved? How to arrange locating holes?(4) … Read More “Six principles to do well in circuit board” »
Learning a new technology will always encounter various problems, and learning EMC is no exception.EMC (electromagnetic compatibility) includes two parts: EMS (electromagnetic sensitivity) and EMI (electromagnetic interference). What we usually say is to solve the problem of external radiation interference of electronic equipment, or how to prevent equipment and electronic components from being interfered by … Read More “Top 10 classic questions about EMC” »
When electric leakage or induction electrification occurs in household appliances, there will be a “numb hand” feeling. If the test pencil is used for inspection, both of them will make the neon bubble of the pencil red. If it is only inductive electricity, these appliances can still be used. If it is electric leakage, it … Read More “How to distinguish between inductive current and leakage” »
Electric Current The directional movement of the charge is called a circuit, and the current is often represented by I. Current is divided into DC and AC. The size and direction of the current do not change with time is called direct current. The magnitude and direction of current change with time is called alternating … Read More “What are the basic concepts of circuit?” »
