Is your peak reflow temp exceeding the LED spec? We store our SMT LED reels on the rack with the rest of the discreets and have never seen this issue...

hi, lately I have problem with smd leds.After reflow 2-4% of leds are broken.I think , that reason is bad storage of components, because in our stock the tape with leds have not Moisture Barrier Bags.My question is ,how you storage components, which

The standard J-STD-033B.1 addresses how to store moisture sensitive components. A dry box is a good, convenient way to store MSDs, but there are other methods to consider which are outlined in the standard. Are you sure that the problems are caused

Some things you have to be sure of... Can you guarantee the LEDS are DRY when you receive them ? They may be packed in dry bags but when was this done and has the LED distributor had them open at his site ? Using vacuum sealed dry packs is a good way

Suggest looking at the packaging,is it sufficient to prevent damage to the QFP?. What way are these components stored when received?.Are the reels stored in boxes or racks?.Storage in boxes may cause damage from stacking the reels on top of each oth

Help! I have a small SMT section that produces low volume but high mix assemblies and, therefore, has over 300 devices. I am looking for a low cost flexible storage solution and believe I have an idea which I recall is available but I cannot find w

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
