ICT 訓練課程. 左亮亮 2002.5.22. 一 .ICT 的功能. ICT也叫在線測試儀，是一台靜態元件測試儀，它能准確，高速地測量PCB上已裝元件的不良問題，包括元件的漏件，錯件，裝反，空焊，來料不良，PCB上金道之間的開短路等。可測元件包 括：電阻，電容，二極管，三極管，電感，變壓器， IC 等絕大多數電子元件。. 二 . ICT 的硬件結構. ICT包括ICT系統主機，電腦系統，壓床，測試治具。其中ICT系統主機包括：電源部分，量測控制板，I/O卡，DC量測板，AC量測板，開關板，HP-JET量測板，高壓量測板(選配件)。. 三 . ICT 的基本測試原理. - PowerPoint PPT Presentation
