PCB Waterproofing Treatments

Printed Circuit Board (PCB) Waterproofing Treatments

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).
