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

What's the issue? Solderability or performance of the component

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

root around the following site http://www.faradnet.com/ ... you should find some good stuff on capacitors

Thank you for the feedback guys. The concerns I have is related to components' performance as well as chipped-off & cracks. Does the performance also degrading over the time? thx

I'll respond directly to your question about capacitor fabrication in a later posting, but more importantly and possibly more directly in response to the situation many hands touch your capacitors before you do. Each of these stockroom personnel, UP

Hi Dave, Thanx for your reply. What is it in the process of manufacturing the capacitor that can go wrong until it can caused the chips to be chipped-off or cracks. I've encountered alot of this problem lately. First I thought it was our process t

Most of the component vendors I've dealt with will guarantee the solderability of the terminations for three years if the components are still packaged in a full reel. If the reel is part used we've kept them for 1 year and then used a wetting balanc
