The circuit tester is a simple test instrument which only shows whether the circuit is intact or whether there is a break . 電路導(dǎo)通器是一種簡(jiǎn)單的量測(cè)儀表,它只能檢查電路的通斷狀況。
Outlet circuit testers and similar indicating devices 輸出回路測(cè)試儀和類似的指示裝置
Structure of system software of gh3183 integrated circuit tester 3183集成電路測(cè)試儀系統(tǒng)軟件的結(jié)構(gòu)
An in - circuit tester tests a digital ic using the ic ' s truth table 在線測(cè)試設(shè)備采用真值表來(lái)測(cè)試數(shù)字集成電路。
The first test an in - circuit tester performs is a shorts - and - opens test 在線測(cè)試完成的第一項(xiàng)測(cè)試任務(wù)就是短路、開路測(cè)試。
After performing the shorts and opens test , the in - circuit tester tests each component on a pcb assembly one at a time 在線測(cè)試完成的第一項(xiàng)測(cè)試任務(wù)就是短路、開路測(cè)試。
After performing the shorts and opens test , the in - circuit tester tests each component on a pcb assembly one at a time 短路、開路測(cè)試完成以后,在線測(cè)試儀需要在同一時(shí)間對(duì)印刷電路板上的每一個(gè)器件進(jìn)行測(cè)試。
These testers cost less than in - circuit testers , and some manufacturers claim that tests run faster on mdas 這些測(cè)試設(shè)備所需要的費(fèi)用要比在線測(cè)試設(shè)備少,而且有些制造商還宣稱在生產(chǎn)缺陷分析設(shè)備上,測(cè)試速度進(jìn)行的更快。
In - circuit testers can now also test for solder opens on surface - mounted devices ( smds ) , a common manufacturing defect on boards with smds 對(duì)于表面安裝設(shè)備來(lái)說(shuō),焊接開路是一個(gè)很普遍的制造缺陷,在線測(cè)試設(shè)備可以將其測(cè)試出來(lái)。
For complex boards or boards that aren ' t tested with an in - circuit tester , most companies perform a functional test before final assembly 對(duì)于復(fù)雜的電路板或者沒(méi)有經(jīng)過(guò)在線測(cè)試的電路板而言,很多公司在最后裝配之前進(jìn)行功能測(cè)試。
