Hello Christopher You should do just fine without vacuum evacuation of the bag. Just squeeze out any excess air. Just be sure that you use active desiccant (I.E. fresh or baked). This assumes normal environmentals. I suggest that you download the

Hi Christopher, To my knowledge, heat seal along will not provide you the desire condition. Currently, we're using vacuum sealer to reseal all MSD restock items. If you have variety of package and constantly need to reseal the MSD parts, I'd like to

JEDEC standard EIA/JEP124 Section 5.2.1 Packing Moisture-Sensitive Components has words to the effect: "...Partially or lightly evacuate the bag to reduce packaging bulk and heat seal the bag as close to the end as possible following the heat sealing

Truthfully, there are pro's and con's for both technologies. (put cost of ownership aside for one moment) Nitrogen won't dry humidified components as rapidly as a desiccant dry box. I'm talking about a self regenerating dry box that uses molecular s

Left to its own devices the plastic used to seal your parts will take-on moisture in the air. When you heat there parts the water in the part expands and can damage the part, if not properly demoisturized. The instustry standards for controlling su

| Greetings, | | We are discussing what should and what should not be baked and vacuum packed. Should we just concentrate on the fine pitch packages and the bga's? | What about those components which come on blister tape, should they get baked and r

Victor, here are a few more elements of information to answer your question. Both the temperature and relative humidity on the manufacturing floor have a significant impact relative to the rate of diffusion of moisture inside a plastic package and t

Hello, Manufacturing process with high moisture and humidity environments and long term storage will definitely see pop corning effects once high temperature from soldering and/or re-flow process. The moisture that has been adsorbed is likely the ro
