simpel answer is yes it will need to be baked, the typical shelf life for a sealed component assuming it has been sealed would be a max of 2 years but some are shorter. The bugger problem with the device may well be solderability of the device!

I have a MS level 3 component that has been on the shelf for 7 years. Should it be baked before usage. The HIC card reads ok- and it was stored with desiccant. History of the part is unknown, was purchased from franchised distribution.

Ideal storage conditions to stop pcbs absorbing moisture is at less then 5% RH, for example in sealed moisture barrier bags. You mention that storage was at 40~70%...at these levels the pcb will absorb quite a bit of moisture. Your baking time was no

Hi, I am new in this industrial. I learnt that PCB may absorb moisture and eventually caused delaminate after heat apply on it (reflow or wave). But I don't quite understand, if the PCB was keep in sealed bubble bag, and with the humidity control wit

Thanks. If based on your statement, I can understand why it still can absorb moisture. But the PCB supplier was suggested us to keep at 40%~70% RH, if any issue occur with the storage condition of less than 5% RH, I think it is difficult for us to ge

Hi, can someone give definition on pot life? does the pot life start once it's been taken out from fridge or the pot life starts once recommended thawing ends?

It depends: * If you're talking jars, I'd be as conservative as possible. So, 3 days from when the jar is removed from the frig would be my pot life limit. * If you're talking Semco cartridges, I'd be talking about 10 days from when the cartridge is

Tantalum caps degrade over time. You should not be seeing "chipped-off & cracks" regardless of the age. This should not be a shelf-life issue, unless you are storing them in an aquarium. Tell us the story. Solderability is a shelf-life issue and

Hi.. What is the typical shelf life for chips capacitor 0603/0402 and what is the consequences of using the capacitor which more than 1 year old esplly on double reflow process. Pls help and thank you in advance. cheers
