Hi All, I have been tasked with a project on the control of moisture sensitive devices and I was hoping to get some input from the experts out there... How do you monitor total exposure time for a MSD? If the packaging has been opened and re-sealed a

Stick a label on the package with the initial opening time and date & the use by time, then check before using again. Use the disposable indicator cards - if the are attached top the waffle packs they are getting the same exposure. Get your supplie

John, I assume you mean 60%, not 65%. J-STD-033 has a derating table for floor life which accounts for conditions other than 30C/60% RH. Table 7-1 is what you're looking for I believe. Adam

You need to account for the time and exposure of each MSD component during your production processes. * Barcodes * Software * Procedures * Training * Etc Francois Monettet [fmonette at cogiscan.com ] at Cogniscan [ cogiscan.com ] is a frequent contr

The main problem that we have is the packaging for the MSD's can be opened and re-sealed a number of times before it hit's production, then it is opened again to be loaded into the machine and most of the time these parts are not consumed so they are

Hi Bryan, I hope you dont mind a quick sales pitch here. We have developed a system called HumiTel which is used to manage MSDs. Its not the paper tracking system you mentioned; it comes in two flavours, a hardware tracking device and a software whic

There is a system out there called Humitel from Brock Electronics. I havn't used it but saw it at Apex. You may want to call them to find out more about it. From what I know they have a sensor that attaches to the tray or reel that will constantly

Hi Gavin, Depends on what MSD class, but in general for the more sensitive parts if they've been opened & not used within the time limit it's rebake, add dessicant & seal. Our distribution side splits them down into more manageable/production size

Hi mates, any production floor controls that are efficient and effective? to control MSD. am talking about practical shopfloor "good mfg practices".

Your ppl are correct, the capacitor is not sealed. So, it is perfectly acceptable for the capacitor to have absorbed moisture. If your ppl don't either prevent moisture absorption or remove the moisture prior to soldering, their component could fail
