常见问题(FAQ)

问:三防漆主要有哪几种体系?

答:主流包括丙烯酸、聚氨酯、环氧树脂与有机硅体系,其中 UV 固化丙烯酸因速度快、无溶剂挥发,正逐步替代传统溶剂型成为电子涂覆优选。不同体系在柔韧性、耐温、附着力上各有侧重。

问:丙烯酸(UV)三防漆相比溶剂型有什么优势?

答:UV 三防漆固化速度快、几乎无溶剂挥发,更环保且产线节拍高;漆膜均匀、可控性好。相比溶剂型,它显著降低 VOC 与气味,更符合汽车制造与工业的环保要求。

问:三防漆涂覆前需要做哪些表面处理?

答:须先清洁 PCB 上的助焊剂、油污与颗粒,必要时进行等离子或烘烤除湿处理,确保漆膜与焊点、基材良好附着。对部分低表面能区域可配合底涂提升防护连续性。

问:三防漆的厚度和固化如何控制?

答:涂覆厚度通常控制在 25–100μm 以满足防护又不影响散热与测试。UV 体系需保证紫外光照强度与能量足够、照度均匀;双固化体系还需热固化补强阴影区,确保完全固化。

问:三防漆如何满足汽车/工业可靠性要求?

答:需关注耐湿热、耐盐雾、耐化学腐蚀与附着力,并符合无卤、低卤及环保法规。对汽车电子,建议选用兼具优良防护性、附着力与抗化学性的体系,并做温循、盐雾等可靠性验证。
