style="text-indent:25px">pcba自動光學(xué)檢查通常在回流前后使用，是較新的確認制造的方法，對元器件的極性、元器件是否存在的檢查效果比較好。它是一種非電氣的、無夾具的在線技術(shù)。其主要優(yōu)點是易于跟隨診斷、程序容易開發(fā)和無夾具；主要缺點是對短路識別較差，且不是電氣測試。3.功能測試（Functional Test）功能測試是早的自動測試原理，它是特定PCB或特定單元的基本測試方法，可用各種測試設(shè)備來完成。功能測試主要有終產(chǎn)品測試（Final Product Test）和新實體模型（Hot Mock-up）兩種。浙江多層PCBA電路板生產(chǎn)商</p><p
