Waterproofing treatments for printed circuit boards (PCBs) are methods used to protect the PCBs from damage caused by exposure to water or other liquids. This can include applying a coating of waterproofing material, such as a conformal coating or potting compound, to the surface of the PCB. Other methods include encapsulating the PCB in a sealed enclosure or using specialized connectors and seals to prevent water from entering the circuit. The goal of these treatments is to protect the PCB from short circuits and other damage caused by moisture, which can cause corrosion and degrade the performance of the circuit over time.
Aculon's NanoProof™ Series offer customers a range of PCB waterproofing solutions from protecting against accidental water damage (NanoProof 1.0) to IPX7, immersion in water at one meter depth for 30 minutes (NanoProof™ 3.5, 4.0), to greater barrier properties that can withstand 100 hours immersion in sweat solutions and some of the most stringent test methods developed for non-hermetic components (NanoProof™ 5.0).
