I have an MSL3 part (a relay) supplied in tape and reel. From what I am able to determine, these parts require baking at 257 degrees F for a minimum of 8 hours once the integrity of the seal is broken for over 168 hours. How are parts baked at th

According to J-STD-033 Table 4-1, the bake out time to restore the clock to zero is not only determined by the MSL level, but the package thickness as well. Section 4.2.2 states "SMD packages shipped in low temperature carriers may not be baked in t

We decided to bake components in tray package at 70 Degree prior soldering. I am looking for suggestion regarding baking time for MSL3 components: Up to 1.4mm package thickness 1.4-2 mm thickness 2-4.5 mm thickness In JEDEC-033B this temperature is n

Hi, are you dealing with Leaded or Lead Free P-BGA ? soldering by Lead or Lead Free paste ? Any way, some time, bridges can be caused by moisture entrapped in the BGA body. Make sure if is respected the correct MSL's allowed flore exposure time, ot

Is normal DI rinse cycle enough to wash away all residue after SMT assembly of high density substrate? This substrate would later be over molded to form MCM module package and I am seeing delamination in high density areas of the substrate at MSL3

Hi all, Wanted to get some input from you guys and gals, I have check the archives and found not much. I am putting together an MSD program here at the company i work for, and was wondering how other people are tracking their times in/out for compone

We used a custom label that we would put on the parts packaging. The label would indicate the MSD level, the maximun hrs of exposure allowed. Also it had fields that whoever opened up that part would write down the date and time the packaging was ope

Hi, do you know if your LEDs are moisture sensitive ? And if so what MSL level ? Surprisingly it seems that not all are, but some seem really sensitive. I imagine the differences are down to the plastics used and the LED manufacturing processes. I a

This is probably a stupid question but how come it is so hard to find moisture sensitivity levels from some manufacturers. Data sheets don't show this information.Is there any easy way of finding this out other than contacting the manufacturer or doi
