Here's a link to the article that Loco references in the above post: http://www.smtnet.com/library/files/upload/DevelopingaReliable.pdf The table seems to be taking a simplistic approach. J-STD-020C, Table 4-2 lists nine catagories of MSL classific

Good day, J-STD-033A: 4.1.2.2 Moisture Sensitivity Levels 5-5a For moisture sensitivity Levels 5 and 5a with floor life exposure not greater than 8 hours, a minimum desiccating period of 10X the exposure time is required to dry the SMD packages en

Does anyone know of a handy dandy reference guide showing what the standard feeder tape size is for most common SMD packages? Just trying to figure out what the capacity REALLY is of all these pick and place machines I'm looking at, that state capaci

Yes, your statement is correct. J-STD-033B.1 section 5.3.3.2 SMD packages not sealed in a MBB may be placed in a dry atmosphere cabinet, maintained at not greater than 5% RH. Storage in these dry cabinets may be considered equivalent to storage in a

You will not see any reduction in quality. Some of the only reasons to hold off on converting to SMD packaging is Cost and availability. The cost normally runs about 30% more and the lead times are about 2 times as long for SMD. For that reason you w
