华测静电放电模拟器hest883c cdm
一、华测静电放电模拟器概述
人体模型(hbm)和机器模型(mm)都是由于ic外部的静电放电造成ic等器件损坏，研究证明ic等器件本身由于接触分离及摩擦如从管内倒出带电，在接触或处理器件如由机器手或人取出时器件会发生放电，在流水线上最常见的esd就是典型的cdm静电放电。cdm与hbm和mm无论在试验原理方法和程序上都有很大的不同。est883c带电器件cdm模拟器具有试验电压宽、精度高、稳定性好、价格低，保修时间长等优点。

measured hest883c cdm electrostatic discharge simulator
first, an overview of the electrostatic discharge simulator
the human body model (hbm) and the machine model (mm) is the damageto ic devices due to electrostatic discharge outside of ic, studiesshow that ic device itself due to contact friction from the tube asseparation and poured out the charged, in contact or processor byhand or machine pulling device will send a discharge, the mostcommon in line esd is a typical cdm electrostatic discharge. cdmand hbm and mm both in the test methods and procedures are verydifferent. est883c charged device cdm simulator with test voltagewidth, high accuracy and good stability, low price, the advantagesof long warranty etc..
