Suppliers have improved the utility and quality of OSP [organic solderability preservative] solderable surface protection over the years. Be cautious reading too much into older SMTnet [and web in general] conversations about handling OSP. When prop

K: Do you shelf life control rolled solder because of the flux core?

We maintain shelf life on all of our RTV silicon compounds.

Does anyone have any data or views on recommended shelf life / Date of Manufacture for components ?? Regards, Chris.

From Kester's web site: "Flux cored solder wire has a limited shelf life determined by the alloy used in the wire. For alloys containing more than 70% lead, the shelf life is two years from date of manufacture. Other alloys have a shelf life of thr

Curiously... Shelf-life of the plating alternatives has been mentioned several times as a potential issue in these discussions. Tell me is there a market for a simple plastic packaging which could extend shelf life (and hence solderability) of these

Many solder wire suppliers put a on rolls of solder wire either a: * "Date of manufacture" stamp and then specify a shelf life in their product documentation ... OR * "Date of expiration." J-STD-005, 6.2, 6.3, and Table 4, where it states "If the st

Hi, I'm looking for research/study done on solder shelf life by using accelerated aging process ( steam age or dry air oven bake at 150C & etc ) Perhaps you could help to advise correlation of all this acceleration test to actual solder shelf life

I have been asked to supply a maximum shelf life for our assemblied PCB's. I realise this is dependent on so many factors- temperature, humidity, no of layers etc. But does anyone have a formulae for calculating shelf life, or does anyone know of a s

| Is there any industry standards regarding shelf life for components? Also do they very between component type packaging? | Thanks No, but generally, the shelf life of components depends on the environmental conditions of the storage area. So, in a
