For the solution of electrostatic discharge problems, according to the following twelve rules to (prioritize) 1.PCB non insulated casing wire and other wire distance of at least 2.2 mm. This applies to all objects connected to the chassis ground, including trajectory. 2 chassis wire length should not be more than five times its width. Metal objects 3 the circuit without insulation and the opera...

Compared with the electric parameters of transmitter power industry monitoring instruments commonly used with the traditional, gradually to the intelligent, integrated, multi-functional direction, and in the electromagnetic compatibility requirements are also high performance (EMS and EMI test were related requirements). The designer how to choose appropriate EMC design, a decisive role on the suc...

In the design of PCB board, can be layered, proper layout and installation of anti ESD design and implementation of PCB. By adjusting the PCB layout, can be very good to prevent ESD. * multilayer PCB is used as far as possible, the double PCB, the ground plane and power plane, and closely spaced signal earth line spacing can reduce common mode impedance and inductance coupling, so as to achieve th...
