ESD Protection Design Seminar（英文版）(ppt 25页)

资料简介：

ESD Protection Design Seminar（英文版）目录：
1、What is ESD?  
2、What damage can it cause?  
3、Why is the problem growing?  
4、What are the issues for the designer?  
5、How can we measure it?  
6、How can we protect equipment from ESD?

 

ESD Protection Design Seminar内容提要：
ESD = Electro Static Discharge
Generation
Triboelectric (friction causes accumulation of charge)
Induction (field induces charge)
Discharge
Dielectric (air) breakdown
Electric field increases when charged bodies approach each other
Current flow into circuitry
1、Must meet ESD specifications  
2、Select ESD tolerant components  
3、Minimize signal degradation (from R,L & C)  
4、Board space / weight / proper design  
5、Component cost  
6、Assembly cost
7、Lifetime cost  (stability)
8、Test the system  
Human Body Model (HBM)  -  for devices
EIA/JESD22-A114-A
ANSI/EOS/ESD-S5.1-1993
MIL-STD-883 (method 3015)
IEC 1000-4-2:1995  -  for systems
Machine Model (MM)  -  less common
EIA/JESD22-A115-A
ANSI/EOS/ESD-S5.1-1993
Charge Device Model (CDM) - less common
JESD22-c101
