PCB moisture content

Electronics Forum | Mon Jul 16 12:03:42 EDT 2007 | davef

We're aware of no industy acceptance standard for max moisture content of a board. For more on moisture levels, get a copy of: "Removing Moisture from Electronic Components and Assemblies", CS Leech, Jr, Circuits Assembly, May 1994. The article disc

is it necessary to vacuum seal moisture sensitive components? Or can we just seal with desiccant in proper bags?

Hi, if you seal in proper way, it is not necessarily to vacuum. we are specialized in moisture solution for electronics and components. Maybe we could give you some workable advice or solutions. If you are interested, contact me by Skype:dryplus1 o

BGA solderability / moisture

We have some BGA's that don't solder very well. They weren't properly stored in regards to moisture protection. The balls look dull and rough. After reflow there seemed to be a diffinate line between the balls and the solder on the PCB's. I think

"...air evacuation is not required (Figure 3-5). Light air evacuation may be used to reduce the packaging bulk and enhance carton packing (Figure 3-6). Full evacuation shall not be used as it will impede desiccant and HIC performance and possibly lea

LONG TERM Your plans to buy a vaccuum bag resealer and a batch drying oven sound good as you say, but you�re correct. They will not help with this current situation. SHORT TERM If your connections are clean, free of pits and holes with a smooth,
