Upon investigation the Freefly team discovered that the conformal coating (a water resistant protective coating used on the circuit boards) had failed and was chipping off the boards.\u00a0 Our investigation revealed that the conformal coating was not to spec, and would leave the PCBA\u2019s inside Pilot Pro less protected from rain \/ moisture than we designed for.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><strong>BACKGROUND<\/strong><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Pilot Pro is designed to be robust and weather resistant.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Freefly relies on conformal coating for many of our products to help increase the robustness and reliability of sensitive PCBA\u2019s<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">We investigated and determined this issue only impacted around 20 units (you are one of the impacted customers)<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Unless the Pilot Pro was subjected to heavy moisture \/ rain this would not cause any issue with safe operation<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>DISCUSSION<\/strong><\/p>\n<p><span style=\"font-weight: 400;\">There are a few potential root causes we are investigating:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Conformal coating material went bad<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Conformal Coating was improperly applied<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">There was a reaction between some contaminant on the PCBA and the coating which impacted its adhesion to the circuit boards<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>RECOMMENDATION<\/strong><\/p>\n<p><span style=\"font-weight: 400;\">At this time we recommend you send your Pilot Pro back to Freefly for a complimentary checkup.
