Storage Conditions for Finished Goods

Storage Conditions for Finished Goods | 10 January, 2005

Hi. I am looking for information on storing completed PCBAs in a warehouse environment. My current assemblies use standard FR4 material - 4 to 6 layers. Component types range from 0402s to fine pitch QFPs and micro-BGAs. If I were to store this in an "unconditioned" warehouse, could I expect detrimental affect to my product. We are in a high humidity area and temperatures could reach the high 80's.

Does anyone know of some published literature on this topic (spec's, articles, etc.)? Can anyone share their experience or recommendations?

Thanks, Mike.

p.s. IPC-PE-740 has no information on this.

First, we know nothing about your assemblies or how storing them in an "unconditioned" warehouse will affect their performance or post-storage processing.

Second, there are no specifications, because what might be good in one application might not be good for another or may unnecessarly increase their costs.

Third, in trying to understand this better, consider: * Reviewing the specification sheets of equipment similar to yours, like: -- Cisco ONS 15305 Installation and Operations Guide, Release 1.0, A.3.2 Storage and Transport. The equipment meets the requirements in ETS 300 019, Class 1.2 and class 2.2. The supported storage temperature range is -40*C to +70*C. -- Lexel Imaging Systems NY10795, Temperature, Storage: -54 to 85*C -- CKS Holdings Ltd Trackerball Switch Assembly: Storage Temperature:-40*C to +85*C * Storing your assemblies according to the individual parts fabricator instructions for the parts that concern you the most.

I've been storing some boards in my computers and equipment now for about 17 yrs with many different types of ambient conditions. Everything is still working. Keep finished goods in an ESD bag and dust them off once in awhile.
