Conformal Coating Tech

Protective coatings (acrylic, silicone, urethane) shield PCBs from harsh environments. Selective robotic spraying achieves 25-75μm thickness with <5% deviation. UV-curable coatings enable 5-second curing. IPC-CC-830B classifies dielectric strength and fungus resistance. Inspection uses UV fluorescence for coverage verification. Rework requires plasma ablation for removal. Aerospace applications demand MIL-I-46058C compliance. Challenges: Bubble formation mitigation through viscosity control.
