Some print expiry date on reels and some specify a shelf life on data sheets. Two main reasons are that the flux in the wire is a mix of chemicals and over time in storage these can react so soldering performance can be changed. Although I have to sa

Jack: You should use your components promptly. Don't store 'em, only bad things will happen to them. 1 You should store all your components, not just your SMD reeled components, so they are not damaged or their solderability decreased. Check the

Cabinets that utilize nitrogen or desiccator units are available that will accomodate the feeder so the parts don't need to be removed. Simply put the feeders into the cabinet at nite and remove them in the morning. Dr. Storage is one. A Google se

Gary, Here goes for what it is worth. We store all of our SM reels in the SM area in proper trolleys (Mossmann-Tebbs types). They are stored by part number, which sets them into Capacitors by value and size. Resistors the same and so on with induc

You�re correct. This is a messy situation. Do not store components at the bake temperature longer than the time required to dry out the units for use in the reflow. Long storage times at elevated temperatures can cause soldering problems and the

Yes Davef, storage condition and long time remaining on shelf could effect pealing strength, but we experimented that by using Polystirene Carrier Tape also this problem was reduced almost to zero. Df, If I am not wrong when you talk about pr

New developments in bulk feeding are making this process of feeding passive components more and more attractive to the PCB manufacturers, for whom the tape feeding for a long time was the solution. The rapid growth in the number of passive component

Praveen, Once you find out the MS level of your components, you will need to track the exposure time from when the parts are initially removed from their dry bags, through test, programming, taping, and during subsequent dry storage and use of thes

| Greetings, | | We are discussing what should and what should not be baked and vacuum packed. Should we just concentrate on the fine pitch packages and the bga's? | What about those components which come on blister tape, should they get baked and r
