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

Ashok: The real concern about moisture sensitivity is in plastic packaged parts. The plastic packaging used to manufacture surface mount technology devices absorb moisture from the environment. The high temperatures involved in vapor phase/reflow

This massage is for clarifications on storage and handling of Moisture sensitive parts: Does chip resistors,capacitors and inductors need vacuum packing during usage life? For repacking of FPDs to limit reuse, is it necessary to use vacuum seler or s

After a few problems and time constraints on baking moisture sensitive devices, we are looking at solutions to storage rather than going after a rebaking solution. One thing that always bothered me about baking was the oxidation on the lead finish,

Again, that is for packaging, rather than moisture removal or storage. Those guidlines are for several reasons, preventing low pressure outgassing or disassociation of the dessicants, damage to parts or wafer tray due to forces on the evacuated pack

What are you going to fill the chamber with when it needs to be opened? If you use air, will the evacuated components suck up any available moisture? I've never done anything like this with electronic components, but some of the more porous materi

| At Sanders (Military manufacturer), we have only started using plastic parts within the past few years. After being tasked with reviewing the new J-Std-033, it became obvious to me our process for controlling device exposure is weak. We build very

Hi John, I don't know of any posters etc. but specs. are available free on-line at www.jedec.com for classification, time out of packaging before baking is required, bake times & temperatures. My understanding is that it only causes a problem if th

I have three questions on moisture sensitive devices: 1. What is general practice on incoming / receiving inspection of moisture sensitive devices- which boils down to mostly FPDs and BGAs ? Traditionally, FPD packs were opened only at time of use
