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

What are the consequences of having the Moisture sensitive component to be overbaked. Say if the specs. calls for 125 C +/- 5 C for 48 hours, but they components were accidently left in the oven during a weekend, wih the oven still operating, to make

The joint IPC/JEDEC standard currently specifies a limit of one bake cycle, regardless of the temprature or duration. In the proposed revision this will be replaced by a maximum cumulative duration of 48 hours at 125C. The reason identified for thi

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

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,

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

Hi, You might find you also need an oven & dessicant for the re-sealing & re-baking process. We found a couple of second hand Gallenkamp ovens (appear to be well made) & a Komet 20 vaccuum sealer for this. Also those natty little cards that chan

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 lo

Steve, Moisture sensitivity needs to be taken seriously. Being in the commercial end of electronics now, I am using many plastic packages. Unfortunately, moisture sensitivity processing is not black and white and it does require procedures and dis
