Here’s what we seem to know: * There’s a problem with voiding in the solder connections of SMT capacitors * A void is an open area caused by air or process fluid that is trapped within a solder connection * Voids are an allowable condition as long as

You might try to complete all your soldering within a 72 hour or less time frame. For all intents treat your board like a moisture sensitive component after you have baked and completed SMT reflow. Wash, blow dry, and go direct to stuffing and com

The lower the RH in the MBB the better for all moisture sensitive devices. Maintaining less then 5% will mean no parts of between 2a-5a MSL will need drying before use. The calculation uses 10% because it is a sensible amount of desiccant to use base
