ESD測(cè)試過程

 

ESD測(cè)試過程中，偵錯(cuò)能啟動(dòng)並能夠自動(dòng)恢復(fù)到規(guī)格內(nèi)的前提下是可以接受的。

Automatic error recovery is allowed and no operator intervention must be required to recover from the ESD event.

類型Type B:

a) 沒有元件的損毀及需要修理的不良或?yàn)榛謴?fù)數(shù)據(jù)到規(guī)格內(nèi)而進(jìn)行的調(diào)整。

No component damage or failure requiring repair or adjustment to restore data sheet specification.

b) 允許內(nèi)存記憶資料丟失、當(dāng)機(jī)。

Temporary memory loss, latch lockup, or change of operating state is allowed.

c) 需要藉由使用者操作恢復(fù)(例如開關(guān)電源或重新啟動(dòng)系統(tǒng))。

Operator intervention required to restore operation must be straight forward; such as power cycling or system reset.

 

5.3.9  Power Line Transient Test

1)  目的 (Objective)

電源瞬間變化產(chǎn)生大量釋放能量的現(xiàn)象﹐主要是由閃電或者轉(zhuǎn)換感應(yīng)負(fù)載﹐如弧焊﹐ 在工業(yè)領(lǐng)域尤其普遍。

Line transients are large energy spikes that occur on the power line, they are caused by lightning or switched inductive load such as arc welders. They are common especially in industrial areas.

確認(rèn)產(chǎn)品使用過程中之抗電源瞬間變化能力。

These tests are designed to verify compliance of the product to its data sheet specifications while being subjected to a variety of power line transient conditions.
