漆膜開裂主要是在環境因素的作用下，內應力的積累，如固化時的體積收縮或低溫時的收縮，導致內應力的形成。 然後經過冷熱、幹濕交替的迴圈後，塗層與基體的膨脹係數不同，導致介面反復相對位移，從而形成破壞性的內應力。

三防漆塗覆加工出現裂紋主要是因為漆膜過厚，表面張力過高的地方，比如針腳，元器件邊緣等等。 解決辦法是减少漆膜厚度，優化爐溫曲線，保持爐溫不要過高，讓漆膜慢慢乾燥固化，達到最佳效能。 劃痕來自於塗裝過程中的工具或機械劃痕。 在包衣乾燥包裝過程中要特別注意。
在很多产品中，电路板要在复杂的环境中长期工作。例如，有些在潮湿、盐雾、灰尘多的地方运行，有些要承受温度变化大、电磁干扰强的工作条件。这些因素可能造成短路、腐蚀、氧化等问题，影响整机运行。
