We are a military contractor and need to build to IPC610 class3. We are receiving many parts with palladium leads and currently use a No-clean solder paste. We have evaluated OA pastes with very little improvements. Without a touch up of all leads th

Dave i know abt the JEDEC033A specs..but this question is more of PCBA level. The baking temp and time at JEDEC is for MSD devices. I have tried to check IPC 7711 but the criteria does not mention the baking temp and time. Wandering is anyone is awar

The current IPC/JEDEC standard J-STD-033 for moisture-sensitive devices does not include a bake cycle at 90C (it includes cycles at 40C and 125C for non-assembled components in reels or trays). However, the upcoming revision, which should be release
