4.2.7.1 states, ...If the bake temperature is not greater than 90 °C, there is no practical limit on bake time... If I interpret that correctly, then you may keep MSDs in a 40 deg. C oven indefinitely with no adverse conditions. Instead of opting

Homemade cabinet may sound like a simple solution but you need to think about making sure the RH is always less then 5% and everything must be ESD safe....ESD is more of an issue at LOW RH levels...so the glass / plastic in any door needs ESD coating

We manufacture according to military Class 3 standards and we do not vacuum seal any MSD devices. Your current method of dry packing is sufficient as well as dry cabinet or nitrogen storage. A light evacuation of air during the dry packing process

my experience: End '80 beg '90 we use a solution like that. Along the assembly lines, next to P&P machines we use to get dry cabinets (cheap and simple cabinet) where to put inside of SMDs (reel & trays once out of MBB ) during the waiting time from

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

Hi Dason, Here is some relevant information that you might find useful : J-STD-033, section 7.1.2.2 Dry Box : "Components may be placed in a dry box, capable of maintaining 25+/-5C and less than 10%RH. Nitrogen or dry air may be used." In other w

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

John, I have read some of the follow-up's to your question and I am having several dry-cabinets made. Each, for under $500.00. Mcdry, a subsidiary of Seika Corp. is a vendor that has a solid background with moisture-free storage units. If cost is an
