MSL parts storage and care for the hobbyist/small business
Hey All,
Lately I've been fighting popcorning of some 5050 LEDs. I see about a 20% fail rate per panel of 72 LEDs. I ordered them from China and they don't come in moisture protective packaging, unlike my MSL parts shipped from US suppliers, and I dont know how long the LED's were in the warehouse conditions. At least popcorning is the only thing I can think of, with that kind of fail rate.
Profile / solder:
Hold @ 225C (Max 230C) for 50 seconds in a Controleo 3 BD toaster oven. Chipquick SAC305 solder paste.
WS2812B 5050 LED on a reel, specifically. (they have an IC built into the chip)
Data sheet doesn't cover MSL.
I was thinking about getting one of those Ziplock tupperware boxes and a large desiccant device for storage, but I'm not sure how to bake them, and I think they NEED to be baked. I believe 40c is the max temp because of the reel, but any recs on how long? I found a lot of info for IC's but not much for large LEDs. The supplier is no help (I don't speak Mandarin).
Thanks for any info!
