Lei Mao EMC Brother ESD Knowledge Sharing:( board layout and ESD protection device placement, which is critical to suppress ESD, electronic fast transients (EFTs), and transient surges).
It is recommended to follow these guidelines:
1.Place the ESD as close to the input terminal or connector as possible.
2.Minimize the path length between the ESD device and the protected line.
3.Except for differential and similar data address buses, non-similar signal lines should not be parallel as much as possible.
4.Avoid placing protected conductors in parallel with unprotected conductors.
5.Minimize all printed circuit board (PCB) conductive loops, including power and ground loops.
6.Minimize the length of the transient return path to ground.
7.Avoid using transient response paths for common grounding points.
8.For multilayer PCBs, use a ground plane, ground via, whenever possible.
Founded in 2011 with the brand LEIDITECH, Shanghai Leiditech is a national high-tech enterprise. The company's R&D team is formed by Dr. Liumei and TI original development manager, with a skilled R&D team and experienced experts in the electromagnetic compatibility industry, mainly providing anti-static TVS ESD and related EMC components (discharge tube TSS GDT, voltage regulator ZENER, varistor MOV, rectifier diode Rectifier, resettable fuse PPTC, MOSFET, inductor).
Leiditech focuses on EMC electromagnetic compatibility to serve customers, and has built its own free laboratory to test electrostatic ESD (30kV), group pulse EFT (4kV), surge (8 20, 10 700 10 1000), automotive load dumping (7637 5A 5B) and component performance testing. Leiditech keeps up with the pulse of technology update at home and abroad, and constantly innovates EMC protection solutions and related devices, with the goal of small packaging, high power, and reliable solutions and components for domestic substitution.
*Information: Product Information:information of esd
electrostatic discharged protection devices, referred to as esd. it is mainly used to protect the electrostatic discharge of communication interface .
the reason of electrostatic discharge：
a. two substances via the contact friction and loss of electrons or the electron, the charge band (no flow) termed static;
b. due to switch electricity or lightning induced surge also indirect causes static electricity;
c. temperature and humidity affect the turboelectric charged, at less than 45℃, it will produce higher humidity greater voltage more than in 55℃, damaging also relatively large.
the selection tips of esd
1. the vrwm is bigger or equal to the circuit working voltage is better;
2. the cp of esd is confirmed by the rate of data port, the data transfer more faster ,the cp of esd should be more smaller;
3. selecting suitable ipp for your circuit, the suitable vc for your circuit and power=ipp*vc*power factor;
4. according to the pcb to select package (1-channel or multi-channels).
