About: Power-off testing

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Power-off testing is often necessary to test the printed circuit assembly (PCA) board due to uncertainty as to the nature of the failure. When the PCA can be further damaged by applying power it is necessary to use power off test techniques to safely examine it. Power off testing includes analog signature analysis, ohmmeter, LCR Meter and optical inspection. This type of testing also lends itself well to troubleshooting circuit boards without the aid of supporting documentation such as schematics.

  • 不送電測試是測試电路板的一種方式，因為不確認电路板是否，以及失效的情形，因此不直接將电路板接電源進行測試，改用其他較安全的方式進行測試，避免因為電路板失效時送電，而使电路板進一步損壞。 不送電測試包括、歐姆計、以及光學檢測。這類的測試也可以在沒有線路圖的情形下進行電路板的排错。 (zh)
