FPC加工廠在進行工控FPC中焊點失效的原因

隨著電子產(chǎn)品小型化、精密化的發(fā)展，F(xiàn)PC廠加工廠采用的工控FPC加工裝配密度越來越高，電路板中的焊點越來越小，機械、電氣、熱力學負荷越來越重，對穩(wěn)定性的要求也越來越高。然而，工控FPC焊點在實際加工過程中也會出現(xiàn)故障。有必要分析和找出原因，以避免焊點再次故障。今天讓我們來看看吧！ 工控FPC加工焊點失效的……

防止工控FPC過期與后續(xù)的處理方法

FPC烘烤的主要目的是去除水分和水分，去除工控FPC中或從外界吸收的水分，因為工控FPC本身使用的一些材料很容易形成水分子。 此外，F(xiàn)PC生產(chǎn)放置一段時間后，也有機會吸收環(huán)境中的水分，而水是工控FPC爆炸板或分層的主要兇手之一。 因為當FPC放置在溫度超過100℃的環(huán)境中，如回焊爐、波焊爐、熱風平整或手焊時，水會變成水蒸氣，然后迅速膨脹其體積。 工控FPC加熱速度越快，水蒸氣膨脹越快；溫度越高，水蒸氣體積越大；當水蒸氣不能立即從FPC中逃逸時，很有機會支撐工控FPC。 特別是FPC
