We have used the Cogiscan system successfully here for 3 years or so now I think its been. I couldn't possibly imagine tracking MSL's on a lot of parts by hand... and being able to trust your numbers. This software will track everything for you and a

In an oven over 100 C any moisture will escape through vents. There will not be huge volumes of moisture in the oven when you are baking components so it should easily escape through vents / holes in the system leaving you with a humidity of near zer

The best way is to have proper system in place that shows which reel is stored where. Now mycronic, juki, fuji and more have these towers(MSD), where you can keep your parts in. It is a very elegant solution with a beautiful software that tells you w

Careful with the term "vacuum sealing". You do NOT want vacuum in the MBBs. If you take out too much air you can create pockets where the moisture gets trapped. Also you can cause corners to pierce the bag. And you can even cause moisture to be pul

Hi John, There are different types of cabinets available with desiccants or Nitrogen/dry air. The best choice depends on many factors in your production environment. The most important consideration for level 4 components, is to make sure that your

Not too sure about that compressed air idea.... How dry is the air? Will it be monitored for moisture content? Given that the air IS dry enough (less than 5% RH) You will have to supply compressed air 24hrs per day, without any disruption in flow

I'm not sure this would solve your problem but Inovaxe has done a good job of solving MSD and inventory handling and control. They are also a sponsor of SMTnet...here is their SMTnet listing followed by thier web site for their carts... http://www.sm

We use a normal off the shelf (Best Buy) mini fridge. As far as the temp readings, I got some USB dataloggers from Omega and stick them in there. Download the data to your PC every couple of weeks (Outlook reminder). I also use these for our Nitrogen

Hi Sergey, I agree with your probable cause. Maybe if you still have a component you can bake it before reflow to DRY it. Then if the problem doesn't happen in reflow you have surely proved the cause. Consult IPC JEDEC 33B spec for storage and Drying

Phil, here is why "dry cabinet storage may not stop the clock" : The moisture diffusion inside a component is actually quite complex. When previously exposed components are returned to dry storage, the moisture gradient that is already absorbed in
