Fugtfølsom håndtering

MSL (fugtfølsomhedsniveau) Overholdelse forhindrer "popcorering" -skader. IPC/JEDEC J-STD -033 definerer bage-out-protokoller: Niveau 3-komponenter kræver 168 timers gulvliv ved<30% RH. Dry cabinets maintain <5% humidity with nitrogen purge. Baking profiles: 125°C for 24hrs for moisture removal. Component packaging includes humidity indicator cards and moisture-barrier bags. Failure analysis detects delamination via scanning acoustic microscopy. High-reliability medical devices mandate Level 1 handling.
