FR-4 Moisture & Temperature Resistance

FR-4 resin bonded fibreglass PCBs are often referred to as moisture sensitive and can come packed with moisture absorbing silica gels, they also have glass transition temperature ratings that should not be exceeded during operation. This video takes an in-depth experimental look at the moisture and temperature resistance of FR-4 PCBs and compares the results to Phenolic PCBs. 00:00 – Intro 00:46 – Normal Moisture 01:34 – Extreme Temperature 02:37 – Extreme Moisture & Temperature 03:43 – Extreme Moisture 04:32 – Extreme Moisture Failure Analysis 10:13 – Outro REF: WT-YT-V-7
